True Pi Day Pie

I made a couple pies for Joshua's math club that focused on pi last week. So here is my favorite one...buttermilk with part of the number pi written on it. I also made a pink lemonade pie which was supposed to be a key lime pie but I didn't have lime juice so I used lemon juice then added pink food coloring to make Tirzah happy! I think I'll make it again, it was delicious!
