  1. I tried this recipe today…TWICE…and both times it failed. There is either something missing or an incorrect measurement. When I made the filling and did not boil it, it did not thicken so when I tried to pour it into the crust it was too liquidy. I tried to pour it back into the saucepan and the crust went with it. So I went back to the store and tried again. The second time it still would not thicken even after a long time of cooking (not boiling) so I added more gelatin, thinking there wasn’t enough, then I cooked it even longer. It never did thicken enough to pour into the crust and then it turned brown from the sugar being cooked too long. So I wasted 6 cups of sugar, 6 limes and 2 cans of condensed milk, a box of gelatin and one crust…quite the expensive little venture! I also called my tenant, who happens to be a manager at an Outback Steakhouse, and she even said that the first couple of times the chef’s tried to make it that it turned out terrible! Plus 3 cups of sugar seems like an exhorbitant amount. Could it possibly be 1/2 cup of water, or more gelatin…or ???? Whatever…I’m a pretty good cook but this recipe sure doesn’t work. I have a much easier one; 1/2 cup Key Lime juice, 3 egg yolks and 1 can condensed milk….mix together, pour into a prepared crust & bake for 15 minutes @ 350 degrees; it’s MUCH easier and delish!

    Somebody please correct or explain this recipe better!

    Boo hoo…..I wish I had read Georgannes comments but I just wrote down the recipe and made pie. It flopped, stayed runny. My husband suggested that my messurements were off so I tried again but added an extra pack of unfavored gelatin. Less runny but now kind of rubbery on top and separeted at the bottom to a clear jelly. Tasted good but whatever, I will return to the old tried and true recipe on the side of “Nellie and Joes Key West Lime Juice” bottle….1/2 cup lime juice, 3 egg yolks, 1 can sweetened condensed milk blended together then poured into a graham cracker pie crust and baked at 350 for 15 minutes. I have made this for years and never had it fail, several have asked for the recipe. Why did I try the above you ask? I had a piece of key lime pie at the outback and it was different than mine. Hope this helps. Cheers, KC

    I think the regular recipe with egg yolks is much better, don’t know why you would do it this way/what the benefit would be?

    The real filling is very simple:
    4 1/2 cups condensed milk
    1 1/2 cups Nellie and Joe’s key lime juice.

    This is all that is really used in the filling.

    I just made a pie last week. I used
    15 keylimes-squeezed myself
    1 can sweetened cond. milk
    4 egg yolks
    about 3 tablespns lime zest.
    I would probably add a little cream cheese
    next time for texture.
