When you start baking, it is advisable to first sieve the ingredients to be used properly, so that there are no lumps in it and that makes processing a lot easier. That is why a good sieve cannot be missing in your bakery. Because you use multiple ingredients, you often also need several sieves. The structure of powdered sugar is different from that of flour, so you cannot use the same sieve for these ingredients. Baking and Cooking has a large diversity of sieves that fit with the various ingredients.
In addition to sieves, Baking and Cooking also has various funnels that make mixing ingredients a lot easier.
