Pi Day in Philadelphia is March 14 (3.14), and in the city and surrounding areas there are plenty of mouthwatering and interesting ways to celebrate.
Double Trellis
Double Trellis is taking the tasty holiday up a notch by adding a charitable incentive to it. Locals can place their order now for either a ginger five-spice apple streusel, toasted sesame and honey, or miso-caramel brownie pie—all of which are made from scratch with recipes from the Director of Programs, Adrian Carnecchia (a Philly pastry veteran.)
Each pie costs $50, and each one sold provides 10 free meals to Philadelphians in need. As a release notes, pies can be picked up between 5 and 7 p.m. on March 14, or noon to 4 p.m. on March 15. Any pies not picked up on time will be donated to one of Double Trellis’s partner programs. For those who simply wish to donate a pie, you can do so by emailing info@doubletrellis.org with your receipt, name, and which pie you are donating (if you order multiple pies.) Orders can be picked up at the Dorrance Hamilton Culinary Center (310 S. 48th St.)
Ordering can be done through flipcause.com, and more information on Double Trellis can be found online.
Night Kitchen Bakery
This Friday, Night Kitchen Bakery will be offering slices of apple and pecan pie for only $3.14 in honor of Pi Day in Philadelphia. While there, locals can also order up some of their specialty cakes, “Best of Philly” brownies, and fan-favorite sticky buns.
