Strainer: Definition and Cooking Information

A strainer, commonly found in almost every kitchen, is an essential culinary tool designed to separate and remove solids from liquids or to sift finer particles from coarser ones. It typically consists of a metal or plastic mesh held within a frame. The sizes and shapes of strainers can vary, ranging from large, bowl-like colanders to fine, handheld mesh sieves. Strainers are indispensable in a range of cooking and baking tasks, such as draining cooked pasta, washing fruits and vegetables, and sifting dry ingredients like flour and powdered sugar. Their primary function is to allow the passage of liquid while retaining solid matter, effectively separating the two components for various culinary purposes.

Types of Strainers and Their Uses

Strainers come in an array of types, each suited for specific tasks in the kitchen.


Colanders are perhaps the most recognized type of strainer. They are large, bowl-shaped, and feature numerous perforations. Ideal for draining pasta, rinsing vegetables, or even washing larger fruits, colanders are a staple in many kitchens.

Fine Mesh Strainers

Fine mesh strainers have a tightly woven mesh making them perfect for tasks requiring precision, such as sifting flour, straining custards, and rinsing small grains like rice or quinoa.

Specialty Strainers

There are also specialty strainers, such as tea strainers, chinois (a conical fine mesh strainer), and skimmers (with larger, spaced holes for removing foam or large particles from liquids).

Choosing the Right Strainer

The selection of a strainer should be based on the intended use.

Size and Shape

The size should correlate with its use; larger colanders are suited for draining pasta, while smaller mesh strainers are for sifting dry ingredients. The shape also matters: conical strainers are excellent for sauces, while flat-bottomed ones are better for larger quantities of food.

Material and Durability

Stainless steel strainers are durable and rust-resistant, making them a long-lasting choice. Plastic strainers are lightweight and often less expensive but may not withstand high temperatures as well as metal ones.

Proper Usage of Strainers

Effective use of a strainer can significantly impact your cooking process.

Draining and Rinsing

When draining boiling pasta or vegetables, ensure the colander is firmly positioned in the sink to avoid accidents. For rinsing, distribute water evenly over the produce to prevent bruising.

Sifting and Dusting

For sifting dry ingredients, gently tap the side of the strainer to aid the sifting process. Strainers can also be used for dusting desserts with powdered sugar or cocoa powder.

Care and Maintenance

Maintaining your strainers is crucial for their longevity.

Cleaning Techniques

Most strainers, especially fine mesh ones, should be cleaned immediately after use to prevent residue from hardening. A soft brush can be used to dislodge particles.

Storage Solutions

Store strainers in a dry place to prevent rust and deterioration. Nesting different sizes can save space, but ensure they are completely dry to avoid mold growth.

Versatility in Recipes

Strainers are not just for basic kitchen tasks but also play a significant role in gourmet cooking and baking.

Stocks and Soups

Using a strainer for stocks and soups ensures a smooth, particle-free base. A fine mesh strainer is ideal for achieving a clear broth.

Baking Applications

In baking, sifting dry ingredients through a strainer can prevent clumps in the batter and improve the texture of cakes and pastries.

Safety and Precautions

When using strainers, particularly with hot liquids or foods, safety should be a priority.

Heat Safety

Always use oven mitts or a cloth when handling a strainer with hot contents to prevent burns.


Ensure the strainer is stable and secure over a bowl or sink to prevent spills and accidents.

Innovative Uses of Strainers

Strainers can be used creatively beyond their traditional roles.

Yogurt and Cheese Making

A fine mesh strainer lined with cheesecloth can be used for making Greek yogurt or soft cheeses by straining out the whey.

Infusions and Flavorings

Using a strainer to remove herbs and spices after infusing oils or syrups allows for a clean, flavor-packed product without residual particles.

Eco-friendly and Sustainable Options

With a growing interest in sustainable kitchen tools, there are eco-friendly strainers available.

Bamboo and Silicone Strainers

Bamboo strainers are biodegradable and offer a sustainable alternative. Silicone strainers, while synthetic, are durable and often considered a more eco-friendly option than plastic due to their longevity.


In conclusion, the strainer is an incredibly versatile and essential tool in the kitchen. Its various types and sizes make it suitable for a multitude of culinary tasks, from the simplest to the most complex. Proper selection, usage, and care of your strainer not only ensure optimal performance but also contribute to the overall efficiency and enjoyment of your cooking experience. Whether you’re a professional chef or a home cook, understanding the functionality and potential of the humble strainer can significantly elevate your culinary creations.
