I forgot to separate my eggs before making the key lime pie. Will the whites really ruin it? Do I have to start over?

However, for a traditional, uncooked Key Lime pie, it would almost certainly be too much liquid.

Thanks. I just went ahead and baked it. I couldn't bear the thought of squeezing another bag of key limes! The texture is slightly different, but it tastes fine.

Depends on the recipe, I think. There are recipes that use whole eggs on just the yolks. Here's one: http://www.foodnetwork.com/recipes/emeril-lagasse/key-lime-pie-recipe.html
