A straining tool is a device used to separate solids from liquids. A SIEVE is one type of straining tool, which is a mesh-like device with small holes that allow liquid to pass through while trapping solid particles. Sieves are commonly used in cooking and baking to separate ingredients, such as flour or sugar, from other ingredients. They can also be used to strain liquids, such as broth or juice, to remove any unwanted particles.
