Just about once a month Emma and I get together and decide on a baking project. She and I went through pastry school together and have pretty similar tastes and skills (although she's a much more precise baker than I am), so baking the same thing in a month means we get to compare notes about the techniques, recipes, and results. Maybe it's a nerdy baker thing we do, but I can't emphasize how important that partnership is in making me a better baker.
