Difference Between Sieve and Strainer

Key Differences

A sieve is designed to separate fine particles from a mixture, commonly used in baking to aerate flour. On the other hand, a strainer is more robust, typically used to drain water from pasta or wash vegetables, where the particle size is not as critical.
Sieves often come in the form of a mesh made from metal or cloth, making them ideal for filtering finer substances like flour or powdered sugar. Whereas strainers can be made from metal or plastic and have larger holes, suitable for separating larger particles or solids from liquids.
In terms of handling liquids, a sieve is preferred for tasks requiring precision, such as making a smooth sauce or custard by removing lumps. Conversely, a strainer is better suited for quickly separating liquids from solids in foods like boiled vegetables or canned beans without needing fine filtration.
Sieves can also be used in the laboratory setting for particle size analysis, highlighting their ability to filter very fine materials. Strainers, however, are seldom used in such precise applications, emphasizing their role in everyday kitchen tasks rather than in specialized environments.
The construction of sieves often includes a frame that holds the mesh tightly in place, ensuring consistent filtration. Strainers, on the other hand, might have a more open design with a handle and a resting edge, designed for ease of use over pots and bowls.

Sieve

A sieve, fine mesh strainer, or sift, is a device for separating wanted elements from unwanted material or for characterizing the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet material. The word "sift" derives from "sieve".

Common Curiosities

Can you use a strainer to sift flour?

While possible, a strainer might not be as effective as a sieve for sifting flour because of its coarser mesh.

Can a sieve be used as a strainer?

Yes, a sieve can sometimes be used as a strainer for finer filtration needs, but it might be less efficient for quickly draining large volumes of liquid.

Is a strainer or sieve better for pasta?

A strainer is generally better for pasta due to its larger holes, allowing for quick drainage of water.

What should I use to rinse quinoa, a sieve or a strainer?

A fine-mesh sieve is preferable for rinsing quinoa, as its small grains may pass through the holes of a coarser strainer.

What is the main difference between a sieve and a strainer?

The main difference lies in their mesh size; sieves have a finer mesh for filtering fine particles, while strainers have coarser meshes for separating solids from liquids.

Can a plastic strainer handle hot liquids?

Plastic strainers can handle hot liquids but are less resistant to heat compared to metal strainers.

Do materials of sieves and strainers affect their use?

Yes, materials can affect durability and suitability for specific tasks, with metal being more durable and suitable for hot ingredients.

How do I choose between a sieve and a strainer?

Consider the task's requirements, such as the size of particles you need to filter or the volume of liquid to drain.

How should I clean a sieve or strainer?

Both should be cleaned immediately after use with warm, soapy water to prevent residue buildup.

Is there a difference in the handle design between sieves and strainers?

Strainers often have handles designed for resting on pots, while sieves might not have handles designed for this purpose.

Are there specialized sieves and strainers for specific tasks?

Yes, there are specialized designs, such as tea strainers or flour sieves, tailored for specific tasks.

Can I use a strainer for tea?

Yes, but finer teas might require a sieve for more effective filtration.

Do sieves come in different mesh sizes?

Yes, sieves come in a range of mesh sizes for different degrees of filtration.

How do I maintain a sieve or strainer?

Regular cleaning and avoiding exposure to extreme conditions will help maintain their condition.
