First Annual Haynes Lab Pie Bake-Off, Summer 2010

Inspired by Ben's amazing pies, group members challenged eachother to a pie bake-off. The rules were simple: (1) must be a sweet pie, (2) must be full-sized, and (3) must have a homemade crust. Four "celebrity" judges chose the winners: Melissa's peach pie, Anushua's mango pie, and Kyle's strawberry pie.

We had a wide variety of pies entered.

After judging, these were declared our 3rd place (strawberry) and 1st place (peach) pies.
