Key Lime Pie

Ingredients

24 Graham crackers (halves), crushed
2 T sugar
1/4 lb salted butter

4 t lime zest
4 egg yolks
14 oz condensed milk (1 1/2 Canadian cans)
1/2 cup fresh lime juice (3-4 limes)

Directions

1) Combine Graham crackers and sugar. Slowly mix in butter until the mixture just holds together - 1/4 cup is probably a bit more than you need. Press into a pie plate, using the bottom of a large measuring cup for a flat bottom. Bake at 350' for 10 minutes. Let cool.
2) Whisk egg yolks and zest until frothy and light green (about 2 minutes).
3) Mix in condensed milk, then lime juice.
4) Pour mixture into crust and bake for 12 minutes. Let cool - the longer the better.
