These accessories are compatible with the Universal Plus mixing machine and are designed for medium to heavy cookie dough, even if you add heavy infuses such as fruits, nuts and candies. Then you can change the hook to beat the butter. If you need to make large batches of cookies (more than 15 dozen) you just have to change the hook before adding the flour. These accessories are the perfect combination, when you are using only scrape the bowl while you are mixing the ingredients so that it is not necessary to use a spatula. These palettes can be washed in the dishwasher.
