Our Test Kitchen created this refreshing mini pie with a homemade crumb crust and a pudding-like lime filling. If you can’t find key lime juice, regular lime juice works just fine.

"I made it as is, then tasted it and it lacked that amazing lime lavor of other recipes. I upped the key lime juice to 3 tbsp. and it still lacked that lime flavor of other recipes. I am leary of adding too much juice so maybe when it's not going on the thanksgiving table I will play around with the recipe some more. I really liked that this recipe doesn't call for any milk product, as we are lactose intolerant."

"Very easy straightforward instructions, nice flavor but I did increase the juice and zest because we like very tart desserts."
