Every week, we scour the Instagram universe to bring you the best food porn fit for a Sunday feast. Yesterday was Pi Day, or 3.14. On this most holy of math-food hybrids, the stars and numerical sequences aligned to give us the most awesome of desserts like toasted meringue pie; some gorgeous lattice numbers from Four & Twenty Blackbirds; insanely flakey crusted cherry pie from Petee’s Pie Company; black bottom oatmeal pie best served à la mode; and French apple “pie” from cookbook extraordinaire David Leibovitz that’s kind of like a pie, but baked in a cake pan and swathed in confectioners sugar icing. If you didn’t get to celebrate yesterday, that’s okay—just do so, today, tomorrow, and the next day. Pie forgives.

Also of note this week: We’ve launched a new hashtag for next-level food pics: #FEASTAGRAM. From here on out, tag your best food photos with the hashtag and we’ll feature our favorites in future Food Porn round-ups each week on the site, as well as here on IG. As Confucious said, “In order to build with fam, you must ‘gram with fam.” Let’s start a movement together.
