I've had my kitchen aid mini mixer for a few years now, but I seldom use the dough hook because I never make bread at home. I have used the hook a total of 5 times max, today I used it to attempt to make Brioche Bread, and after removing the hook I noticed that it was chipped. My machine and hook are not placed too low or high. I still can't believe this happened after rarely using this piece of equipment. I am very disappointed.
