This is a great recipe I found on Allrecipes.com by Ann Richardson. One of the easiest and best key lime pies I've ever made! Since I live in Costa Rica, key limes or sour cream aren't easy to come by. I substitute Natilla (a type of creme fraiche) for the sour cream and Mandarinas (a very sour mandarin-type orange) for the limes. I don't know if it's the heat and humidity here, but I have to bake it for 10-12 minutes to get the pinhole bubbles. But I've left the recipe as Ann wrote it, in case that's what it takes in more moderate weather... Sometimes, I'll add a topping made with natilla, a bit of mandarina juice, and powdered sugar. It is quite tasty! Prep time includes time to zest and juice the limes. Thanks, Ann!!!

I've had this recipe saved to make for a long time, but admit I found & esp liked a no-cook recipe so much that my "trial plan" didn't happen. The no-cook recipe used Cool Whip (hard to find here & now no longer imported). KL pie is a DH fave, so this was made as a trial for a game nite w/friends who also favour KL pie. I made the recipe as written except for using pre-cooked tartlet shells & adding green food colouring. The recipe made 15 tartlets & the lime flavour was excellent. Besides the cook method, the other diff was that the no-cook version was mousse in texture (as you'd expect) & this was cheesecake in texture. As this was a 1st try, I'm unsure if my judgment of cook time may have been a factor. This is an easy-fix, I'm grateful for this option & DH is happy too. :-)

I think this was my favorite Easter dessert this year! I only had a 10" crust on hand, so I was wondering if I needed to double the filling at first because key lime pies are usually pretty thin, but I'm glad I waited to see. I found that when I measured out 3 cups of condensed milk, it was a larger amount than it would have been had I just converted the cups to ounces and used the equivalent amount from the can (approx. 2 1/3 cans of milk versus approx 1 2/3 cans of milk). Not sure which method the recipe creator intended, but the way I made it worked perfectly for my larger crust. I had to bake it for about 12 minutes before the bubbles appeared. I topped it with some cut fresh strawberries for color. The pie turned out very creamy and rich, so smaller slices were satisfying. Delicious and super-simple to make, so I'll be keeping this recipe on hand for future key lime pie cravings. Thanks for posting! Made for PAC Spring 2012
