Pi Day is coming on 3/14 and you better believe there’s only thing you should be cooking on that day- pie. Natch. If you’re going to be baking a pie on Pi Day, or if you’re just a mathematically oriented baker, then the I Bake Pi Apron is what you should be wearing. It’s delightfully nerdy, decorated with a formulaically sliced Pi right on it and even has a pair of pockets to store all calculators or recipes. It makes cooking in the kitchen 3.14159 times as fun.
