Macaroni and cheese

This is good comfort food. I made this recipe for macaroni and cheese, which has a nice panko crust. I thought it might be too crust heavy, but it turned out not to be. The tang of the mustard and pepper flakes was perfect. We used an assortment of cheeses we had to use up, about 2 cups cheddar, 1½ cup gouda, and some parmesan which went into the topping. The sauce seemed watery before baking, but ended up perfect.
