Final answer:
In cooking, breading is sifted after every batch to ensure an even coating on the food being breaded.
Step-by-step explanation:
In cooking, sifting is the process of passing dry ingredients, such as flour or breadcrumbs, through a fine mesh to remove any lumps and aerate them. The purpose of sifting breading is to ensure an even coating on the food being breaded, such as chicken or fish. Regarding how often to sift the breading, the general practice is to sift the breading after every batch. This ensures that any clumps or impurities are removed before breading the next batch of food.
