March 14th marks the annual observance of Pi Day (3/14, see?), but when we hear "pi," it takes us less than 3.14 seconds to conjure up an image of fresh apple pie like this rustic free-form galette. You won't believe how easy it is (as pie?) not only to whip up your own dough, but also a batch of homemade ice cream, no churning required! Once you toss this bad boy in the oven and fill your kitchen with the sweet perfume of baked apples and cinnamon, you'll be circling this day on your calendar for years to come!
