Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.
Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits. You can find more out about Pi Day at the official Pi Day site.
Old Fashioned Apple Pie Recipe
3/4 cup light brown sugar
1/4 cup all-purpose flour
3/4 teaspoon ground cinnamon, plus more for sprinkling
Freshly ground nutmeg, to taste
7 medium apples, peeled and thinly sliced (golden delicious apples work well)
1 lemon, zested and juiced
2 pre-made pie crusts
1 egg, lightly beaten
Place a rack in the center of the over and preheat oven to 450 degrees F.
Mix together the brown sugar, flour, cinnamon, and nutmeg in a small bowl. In another bowl, sprinkle apples with the juice of 1 lemon and toss. Stir in the sugar mixture to evenly coat the apples.
Take pie crusts out of the refrigerator and let stand and room temperature for 15 minutes. Use 1 round of dough line a 9-inch pie pan. Mound the apple and sugar mixture into the pie pan lined with dough.
Using a knife, cut an even number of strips from the remaining dough. Transfer every other strip to the pie top and weave in the lattice by folding every other strip back onto itself and laying another strip perpendicularly. Fold the strips back across and repeat until completed.
Finally, brush the top of the pie with egg wash and sprinkle with cinnamon and sugar. Trim the overhanging dough and crimp edges. Bake pie for 45 minutes. Let rest 20 minutes before slicing.
