Strainer: Types, Materials, Uses, Buying Guide & Care

Introduction

A strainer is a kitchen tool designed to separate solid particles from liquids or separate foods according to size.

It usually works by passing food or liquid through:

  • Wire mesh

  • Fine mesh

  • Perforated metal

  • Slots or openings

while retaining particles that are too large to pass through.

Strainers are commonly used for:

  • Straining tea

  • Draining small quantities of food

  • Straining stocks and broths

  • Removing seeds or pulp from liquids

  • Rinsing rice, lentils or small ingredients

  • Straining sauces

  • Removing particles from liquids

  • Sifting certain dry ingredients, depending on design

The basic principle is:

Food or liquid mixture → Strainer → Smaller material/liquid passes through → Larger particles remain

The term strainer covers a broad range of kitchen tools. A tea strainer, fine-mesh strainer, pasta strainer and sink strainer all perform different tasks, so the correct type depends on the intended use.

What Is a Strainer?

A strainer is a utensil containing openings that allow certain materials to pass through while retaining larger particles.

The filtering surface may consist of:

  • Fine woven wire mesh

  • Coarse mesh

  • Perforated sheet

  • Slotted openings

For example:

Brewed tea + tea leaves → Strainer → Tea passes through → Leaves remain

or:

Stock + cooked solids → Strainer → Liquid passes through → Larger solids remain

The size of the openings determines what the strainer can separate.

This means a strainer designed for tea may not be suitable for pasta, while a coarse pasta strainer may not remove small tea leaves.

How Does a Strainer Work?

A strainer uses physical size separation.

The openings in the filtering surface act as a barrier.

Materials smaller than the openings can pass through, while larger particles are retained.

Its effectiveness depends on:

  • Opening size

  • Mesh fineness

  • Shape

  • Surface area

  • Amount of food being strained

  • Thickness or viscosity of the liquid

Simple example

Tea with leaves

↓

Fine strainer

↓

Liquid tea passes through

↓

Tea leaves remain

A finer mesh captures smaller particles but usually allows liquid to pass more slowly.

A coarser mesh drains faster but allows smaller particles through.

Main Parts of a Strainer

1. Filtering Surface

This is the most important part.

It may be made from:

  • Fine wire mesh

  • Coarse wire mesh

  • Perforated metal

  • Molded perforations

The opening size determines which particles are retained.

2. Rim or Frame

The rim supports the filtering surface.

It helps:

  • Maintain shape

  • Strengthen the strainer

  • Support it over bowls or vessels

The rim should be smooth and securely constructed.

3. Handle

Many strainers have one long handle.

The handle provides:

  • Grip

  • Control

  • Distance from hot liquid

Some designs may use:

  • Metal handles

  • Insulated grips

  • Molded handles

  • Loop handles

4. Resting Hook or Support Loop

Many handheld strainers have a small support opposite the handle.

This allows the strainer to rest across:

  • Cups

  • Bowls

  • Pots

  • Containers

The support must fit securely to avoid tipping.

5. Mesh Basket or Bowl

The filtering section may be:

  • Shallow

  • Deep

  • Flat

  • Basket-shaped

A deeper basket generally holds more food.

6. Handle Joint

The handle may be:

  • Welded

  • Riveted

  • Formed as part of the frame

  • Mechanically attached

This joint should be strong enough for the intended load.

Key Features of a Strainer

Mesh or Perforated Surface

This enables the separation process.

Different opening sizes are suitable for different foods.

Controlled Filtration

Compared with many large-hole colanders, a fine strainer can capture smaller particles.

Handle for Easy Control

A long handle allows the user to:

  • Hold the strainer over a vessel

  • Pour liquid through it

  • Lift food

  • Keep some distance from heat

Multiple Sizes

Strainers range from:

  • Small tea strainers

to:

  • Large kitchen strainers

Lightweight Construction

Many handheld strainers are designed to be easy to:

  • Hold

  • Pour through

  • Store

Hanging Loop

Some strainers include a loop for hanging storage.

Benefits of Using a Strainer

1. Separates Solids From Liquids

This is its primary function.

Examples include:

  • Tea leaves from tea

  • Herbs from broth

  • Seeds from liquids

  • Cooked solids from stock

2. Available in Different Mesh Sizes

Different mesh sizes allow a strainer to handle different tasks.

For example:

  • Fine mesh → smaller particles

  • Coarse mesh → faster drainage and larger foods

3. Useful for Small Quantities

Handheld strainers are convenient when a full-size colander would be unnecessarily large.

4. Useful for Rinsing Small Ingredients

Fine-mesh strainers may be suitable for rinsing:

  • Rice

  • Lentils

  • Quinoa

  • Small grains

provided the openings are smaller than the food.

5. Helps Produce Smoother Liquids

Fine strainers can remove:

  • Seeds

  • Lumps

  • Fibrous particles

  • Larger solids

from suitable sauces and liquids.

6. Easy to Store

Many strainers:

  • Nest inside bowls

  • Hang from hooks

  • Occupy relatively little space

Drawbacks and Limitations

Fine Mesh Can Clog

Small particles can become trapped in fine mesh.

Examples include:

  • Flour

  • Pulp

  • Tea particles

  • Starch

  • Seeds

Fine Mesh Drains More Slowly

Smaller openings restrict flow compared with larger perforations.

Wire Mesh Can Be Damaged

Thin mesh may:

  • Bend

  • Tear

  • Separate from its frame

if handled roughly.

Not Every Strainer Handles Heavy Food

A lightweight tea strainer is not designed to hold:

  • Large quantities of pasta

  • Heavy vegetables

  • Large batches of food

Difficult-to-Reach Areas Can Trap Food

Residue may accumulate around:

  • Rim

  • Mesh-frame joint

  • Handle attachment

Metal Can Become Hot

A metal strainer exposed to:

  • Boiling liquid

  • Steam

  • Hot cookware

may become hot.

Types and Variations of Strainers

1. Fine-Mesh Strainer

Uses tightly woven mesh.

Common uses

  • Stocks

  • Sauces

  • Tea

  • Small grains

  • Removing small particles

Benefits

  • Captures relatively fine particles

Common applications include removing:

  • Dumplings

  • Noodles

  • Blanched vegetables

  • Fried foods

The tool’s exact suitability depends on its material and construction.

8. Sink Strainer

A sink strainer is different from a handheld food strainer.

It sits over or inside a sink drain and helps prevent larger food scraps from entering the drainage system.

It should not be confused with a utensil used directly for food preparation.

9. Clip-On Strainer

Attaches to the edge of a:

  • Pot

  • Saucepan

and allows liquid to be poured away while food remains inside.

Benefits

  • Compact

  • Reduces need for a separate large colander

Limitations

  • Must fit the vessel securely

  • Not suitable for every pot

  • Material must tolerate the intended temperature

Strainer Materials

Stainless Steel

However, regional terminology varies.

Strainer vs Sieve

The two can look very similar.

Strainer

Primarily used to:

  • Separate solids from liquids

  • Drain food

  • Filter liquids

Sieve

Primarily used to:

  • Separate particles by size

  • Sift dry ingredients

  • Break up lumps in flour or powdered ingredients

A fine-mesh tool may perform both functions depending on its construction.

Strainer vs Skimmer

Strainer

Liquid passes through the filtering surface while particles remain.

Skimmer

Usually has a:

  • Flat or shallow perforated head

  • Long handle

and is used to remove material from the surface of a liquid.

Common uses include removing:

  • Foam

  • Scum

  • Floating food

Strainer vs Spider Strainer

Fine-Mesh Strainer

Best suited to:

  • Filtering

  • Small particles

  • Sauces

  • Stocks

Spider Strainer

Best suited to:

  • Lifting larger foods from liquid

  • Noodles

  • Dumplings

  • Fried foods

A spider is generally not intended for fine filtration.

Common Uses of a Strainer

Straining Tea

A tea strainer separates brewed tea from loose leaves.

Choose mesh fine enough to retain the type of tea being used.

Straining Stock or Broth

A strainer can remove:

  • Bones

  • Herbs

  • Vegetable pieces

  • Other solids

from liquid stock.

For very clear stock, progressively finer filtration may be required.

Straining Sauces

Fine mesh can help remove:

  • Seeds

  • Fibres

  • Lumps

from suitable sauces.

Rinsing Rice and Grains

A fine-mesh strainer may be used to rinse grains if the mesh openings are smaller than the grains.

Draining Small Portions

A medium or coarse strainer may drain:

  • Small pasta portions

  • Vegetables

  • Cooked ingredients

provided it has sufficient capacity and strength.

Sifting Dry Ingredients

Some fine-mesh strainers can be used for small amounts of:

  • Flour

  • Cocoa

  • Powdered sugar

However, a dedicated sieve may be better for larger quantities.

Buying Guide: How to Choose a Strainer

1. Decide the Main Use

For tea, choose:

  • Small size

  • Fine mesh

  • Easy-clean design

For stock and sauces, choose:

  • Fine mesh

  • Strong frame

  • Comfortable long handle

For rice and grains, choose:

  • Mesh smaller than the grains

  • Sufficient depth

For pasta or vegetables, choose:

  • Larger capacity

  • Coarser openings

  • Strong construction

2. Choose the Correct Mesh Size

Fine Mesh

Best for:

  • Tea

  • Small particles

  • Fine grains

  • Sauces

Medium Mesh

Useful for:

  • General-purpose straining

  • Some grains

  • Small foods

Coarse Mesh

Useful for:

  • Faster draining

  • Larger food pieces

There is no single mesh size suitable for every kitchen task.

3. Check Mesh Strength

Look for mesh that is:

  • Even

  • Securely attached

  • Free from tears

  • Free from sharp wires

A damaged mesh can allow food through or create sharp points.

4. Check the Handle

A good handle should provide:

  • Comfortable grip

  • Adequate length

  • Secure attachment

For hot liquids, a longer handle can provide greater distance from steam, though it does not eliminate burn risk.

5. Check the Rim

The rim should:

  • Support the mesh

  • Remain rigid

  • Have smooth edges

6. Check Bowl Depth

A shallow strainer works well for:

  • Tea

  • Small quantities

A deeper strainer can hold:

  • More food

  • Larger batches

7. Consider Resting Supports

If you want to place the strainer over:

  • Bowl

  • Pot

  • Cup

check whether it has:

  • Support hook

  • Opposite loop

  • Stable rim

8. Check Cleaning Access

Inspect:

  • Mesh-frame seam

  • Handle joint

  • Rim

  • Support hooks

These areas can trap food.

9. Choose the Right Material

Consider:

  • Food temperature

  • Type of food

  • Cleaning method

  • Durability

Food-contact materials should be suitable for their intended use. FDA notes that food-contact substances include materials associated with cookware and food-preparation surfaces. (U.S. Food and Drug Administration)

10. Verify Material Claims

Do not assume:

  • SS304

  • SS316

  • 18/8

  • BPA-free

  • Food grade

  • Dishwasher-safe

  • Heat-resistant

without reliable product specifications.

Care and Maintenance Tips

  • Wash before first use.

  • Rinse promptly after straining sticky or starchy foods.

  • Do not allow food to dry inside fine mesh.

  • Use a soft brush to clear trapped particles.

  • Clean both sides of the mesh.

  • Pay attention to the mesh-to-rim joint.

  • Clean around handle attachments.

  • Rinse detergent thoroughly.

  • Dry completely before storage.

  • Avoid crushing fine-mesh strainers under heavy cookware.

  • Do not use sharp tools to force particles from mesh.

  • Inspect periodically for broken wires.

  • Replace a strainer if mesh becomes badly torn or develops hazardous sharp edges.

  • Follow manufacturer instructions for dishwasher use.

How to Clean a Strainer

Step 1 — Rinse Immediately

After use, rinse the strainer before residue dries.

This is particularly useful after:

  • Tea

  • Flour

  • Starch

  • Sauce

  • Pulp

Step 2 — Wash Both Sides

Apply suitable dishwashing detergent and clean:

  • Inside surface

  • Outside surface

Food can become trapped from either direction.

Step 3 — Brush the Mesh Gently

Use a suitable soft brush to remove trapped particles.

Brush carefully to avoid:

  • Stretching

  • Tearing

  • Distorting

fine mesh.

Step 4 — Clean the Rim

Pay attention to the area where the mesh meets the frame.

Residue can accumulate in this seam.

Step 5 — Clean the Handle Joint

Wash around:

  • Welds

  • Rivets

  • Attachment points

where accessible.

Step 6 — Rinse Thoroughly

Remove all:

  • Detergent

  • Food residue

Step 7 — Dry Completely

Allow the strainer to drain and dry before storage.

Common Mistakes

  • Using coarse mesh when fine filtration is required.

  • Using very fine mesh for large heavy foods.

  • Overloading a small strainer.

  • Pouring boiling liquid too quickly.

  • Holding the face directly above rising steam.

  • Allowing tea or food residue to dry in mesh.

  • Scraping fine mesh with sharp metal tools.

  • Crushing a fine strainer under heavy cookware.

  • Ignoring broken or protruding mesh wires.

  • Assuming every strainer is suitable for frying.

  • Assuming every plastic strainer can handle boiling liquid.

  • Assuming every stainless steel strainer is SS304.

  • Calling stainless steel completely rust-proof.

  • Using a tea strainer as a heavy-duty food strainer.

  • Confusing a strainer with a colander.

  • Confusing a strainer with a sieve.

  • Assuming “food grade” without documentation.

  • Ignoring residue around the rim.

  • Storing the strainer while dirty or damp.

  • Using a damaged handle or loose joint.

Safety Information

1. Be Careful With Hot Liquids

Straining:

  • Boiling water

  • Hot tea

  • Stock

  • Soup

can expose the user to burns.

Use a stable setup and pour carefully.

Keep hands and face away from rising steam.

2. Do Not Overload the Strainer

A small or lightweight strainer can:

  • Tip

  • Bend

  • Slip

if overloaded.

Match the strainer’s size and construction to the quantity of food.

3. Inspect Fine Mesh for Damage

Broken wire mesh can create:

  • Sharp edges

  • Loose wire fragments

  • Gaps that allow food through

Stop using badly damaged strainers.

4. Use Temperature-Appropriate Materials

Do not expose plastic, silicone or composite strainers to high temperatures unless the product is designed for those conditions.

Material suitability depends on the exact formulation and intended use.

5. Use Appropriate Food-Contact Materials

A kitchen strainer directly contacts food and beverages.

FDA defines food-contact substances broadly to include substances associated with cookware, food-preparation surfaces, processing and storage. The suitability of food-contact components depends on their intended conditions of use. (U.S. Food and Drug Administration)

6. Stainless Steel Is Corrosion-Resistant, Not Invulnerable

Stainless steel obtains its corrosion resistance from a chromium-rich passive surface film. However, corrosion can still occur under certain conditions, including some chloride-rich or aggressive environments. (worldstainless)

For routine care:

  • Clean after use.

  • Rinse thoroughly.

  • Avoid prolonged unnecessary exposure to aggressive residues.

  • Dry properly.
