The use of mittens during cooking has numerous advantages. Many also function as trivets and keep you from slipping when handling hot objects. You must, however, consider the level of protection they offer. Some mitten styles offer less protection than others. For instance, smaller mittens could not offer the same level of protection as larger ones. In such circumstances, you must get larger, thicker versions.
The oven mitts from All-Clad can be washed in the dishwasher. Don’t overwash them, though, since they can shrink or lose their waterproof qualities. Try cleaning them by hand if you’re unsure.
