Every year on March 14th, teachers, scientists, and those who just love math and numbers celebrate Pi Day, a special day that pays tribute to the mathematical constant Pi… otherwise known as the number 3.14 (plus a bunch of other digits that are really hard to memorize). We love any holiday where we can celebrate with pie, and we are sharing our favorite Vegan Raspberry Lemon Tart recipe to enjoy today or any day of the year!
