Main Difference
The main difference between Colander and Sieve is that the Colander is a bowl-shaped kitchen utensil with holes in it used for draining food and Sieve is a tool for breaking or separation of solid materials
Colander
A colander (or cullender) is a kitchen utensil used to strain foods such as pasta or rice or to rinse vegetables. The perforated nature of the colander allows liquid to drain through while retaining the solids inside. It is sometimes also called a pasta strainer or kitchen sieve.
Conventionally, colanders are made of a light metal, such as aluminium or thinly rolled stainless steel. Colanders are also made of plastic, silicone, ceramic, and enamelware.The word colander comes from the Latin colum meaning sieve.
Sieve
A sieve, or sifter, is a device for separating wanted elements from unwanted material or for characterizing the particle size distribution of a sample, typically using a woven screen such as a mesh or net or metal. The word “sift” derives from “sieve”. In cooking, a sifter is used to separate and break up clumps in dry ingredients such as flour, as well as to aerate and combine them. A strainer is a form of sieve used to separate solids from liquid.
