Imagine Hana and Jeanne in aprons, trying to bake something as simple as Brownies. It's feasible.

Until a brownie-batter fight starts and chocolate gets flung everywhere.

The brownies would probably come out right. If Jeanne did most of the work. Then later Hana would try it on her own and either burn the guild down or accidentally kill the first person brave enough to try her brownies. Depending on if she remembers how long to keep them in the oven. x3
