It’s almost time to commemorate one of the most beloved and mysterious numbers in mathematics.

You know - Pi! The ratio of a circle's circumference to its diameter is approximately 3.14. So on March 14 - or 3/14 - math fans and dessert lovers unite to celebrate Pi Day.

In honor of the holiday, we invite you to show off your best pie, or tell us about the tastiest one you've ever had. Sweet, savory, crunchy, creamy - we want them all. Include original photos and recipes, and we'll celebrate the beloved dessert March 14 on Eatocracy.
