Recipe

Make a Key Lime Pie From Scratch with Just 5 Ingredients

By Jocelyn Hsu at University of California – Berkeley

My family loves Key lime pie; it's one of the only pies they'll happily purchase. They love the combination of sour and sweet, along with the tasty graham cracker crust. So when they challenged me to make a Key lime pie over winter break, I obliged. 

They loved it. My dad particularly appreciated how sour the pie was. I made two more Key lime pies over break, and I think it's safe to say that I've perfected the recipe. I'm pretty sure they won't be buying Key lime pie again.
