For the 30th anniversary of Pi Day, Google went there. It made a Pi-themed Google Doodle out of, yep you guess it, pie ingredients. Hilarious.

Pi Day is celebrated every year on March 14—or 3.14—as an homage to the mathematical constant, which is equal to 3.14159.

This year Google decided to mark the 30th occurrence of this event with a nod to "the number's delicious sounding name." The Doodle represents Pi's mathematical formula—the ratio between a circle's circumference to its diameter—in pie form.

Pi Day was first recognised 30 years ago back in 1988 by physicist Larry Shaw, according to Google. And, those wishing to mark to the occasion often do so by enjoying a slice of their favourite pie.

Of course, the pie featured in the Doodle isn't any old pie. Google got Dominique Ansel—the chap who invented the Cronut—to make the Pi pie.

Oh, and if your mouth is positively salivating at this bit of nerdery, Google's got you covered. Ansel shared the recipe for the Pi pie.
