Baking and storing baking tools
It’s a long-held and widespread mystery why why some people’s cookies are not as round as others. It could be because some bakers prefer to make a dough ball and smash it while others cut the yummy dough with a round mold.
Kitchen tools may be expensive, though. In this picture, someone came up with this idea: making a round cookie cutter out of a Pringles can. It looks like they also keep cupcake holders inside the tube. What a fantastic pastry kit.
