This isn't a Key lime pie in the truest sense - I made it with Persian limes, the ones most commonly found in the average grocery store. I have never tried a real Key lime but, it seems that you don't really need it to make a nice lime pie.
The recipe comes from Wanda's Pie in the Sky and is very easy to make. It is the first pie I've made that uses uncooked egg yolks. I wasn't sure how it would turn out, but it was great. It didn't taste eggy and the filling firmed up nicely and was sliceable. The filling was sweet-tart and the coconut in the crust complemented the lime, making it taste more tropical. Overall, I was happy witht the results and would not hesitate to make it again.
