Like Little Jack Horner, we at ScienceBlogs are not above sitting in a corner and sticking our thumbs into pies. Which is why we're not allowed to have pies in the office. Plums are all fine and dandy, but what else we could pull out of these amazing creations? Domestigoth gets creative with the Citric Acid in your Eye Pi, incorporating a chocolate crumble crust, delicious citrus custard, and some semi-sweet double bonds. Yes, that's right, chemistry. In a Pi Day pie. It smarts so good.
