Why do you really have to think about the mixing bowl as an important part when buying a food processor? The material and content and two important reasons. For the material you have a choice of materials such as glass, plastic and metal. When your mixture bowl is made of plastic or glass, you can easily see if your ingredients are well mixed. With a metal bowl of stainless steel, however, you have an advantage when beating protein and cream. This is easy free of grease. In addition, metal is a robust material that is very suitable for heavy work.
The content of your mixing bowl is something to keep in mind when you regularly correct ingredients that increase in volume. For example, think of protein, this expands considerably during the beating. For a nice airy foam you also need enough space. Do you regularly make meringue and pizza dough for the whole family? Then go for the greatest content! If you are more of baking cookies, a slightly smaller mixing bowl is sufficient.
