The size of a sieve’s mesh surface determines its separating power. A larger mesh weave will allow larger pieces of food to pass through, while a finer weave will catch the tiniest particles.
Running food through a sieve creates smooth liquids and light, airy dry ingredients, which make them perfect for straining soups or sauces for a lump-free finish. You can also use them to sift or mix dry ingredients together. Always place a bowl under your sieve before using, just so you don’t lose your smooth.
