Patisse Sieve Stainless Steel with Stainless Steel Mesh Ø20cm (Flour and Flour) Flour can contain bits or leftover husks and this can ruin a dough very quickly. Also, flour is a lot fluffier when it has been passed through a sieve. This sieve makes that very easy. Its large round shape allows a lot of flour to go in at once and it also doesn't take much time to have sifted flour properly. This sieve is fine mesh and is made of stainless steel.
