Don’t Let Pi Day Pass You By!

What makes a pie a pie?

Is it the crust? The circular shape? The way it’s cooked?

Most of the definitions I’ve read recently seem to agree that a pie must be baked and that it has to have a fruit or meat-and-vegetable filling of some sort, but several dictionary and encyclopedia entries sort of waffled a bit on whether a layer of pastry on the bottom, top, or both is necessary. There’s a whole cookbook’s worth of wiggle room in the words “typically” and “generally” and “usually.”

My wife whipped up a crustless quiche this morning to celebrate Pi Day, which seemed to satisfy my kids’ desire for a food properly befitting this most mathematical of days.

Our dinner plans involve taking and baking a pizza from a nearby shop, because pizza is totally a pie, right? I’ve always thought it could sort of slide into that definition, but I just learned of an argument that pizza is actually an open-faced sandwich! I’ve only recently started wrapping my head around the idea that some people consider a hot dog to be a sandwich, because it’s meat between two halves of bread. But pizza? Someone’s oven didn’t fully preheat on that idea.


If what you’re eating today is not obviously a pie, could you make an argument to justify it as one? Now that I think about it, there may be a case for French onion soup …

What We Celebrate When We Celebrate Pi Day


My wife commented to me yesterday that she thinks we celebrate well. Not necessarily in the grand Christmas-anniversaries-and-birthdays sense—or at least not strictly in that sense, because we are pretty good at that. She was talking about the ways we mark smaller occasions: the first day of summer, say, or May the Fourth, or even a Friday evening after a difficult week.

We’ve not historically done too much for Pi Day, which comes every year on March 14 (3.14, yeah?), but this year was a big one, in terms of Pi Days, given that the month, date, year, and exact time for one second could be listed out as 3/14/15 9:26:53. Twice.

I secretly ordered my wife a T-shirt featuring a drawing of a cherry pie with the symbol for pi cut into the crust, and I gave it to her that morning.

For dinner, she baked a shepherd’s pie, followed by chocolate pie for dessert. We grown-ups had Irish cream whipped cream to put on our slices, and I invented a cocktail out of apple pie moonshine, bourbon/rye (I made one of each), and Izze sparkling apple juice.

I also talked a bit about circles and circumferences with the girls, so we did more than just blindly celebrate a day without honoring its roots. I believe that we should keep the Pi in Pi Day. As tasty as pie is, math is the reason for the season.
