The acidity of the lime juice causes the protein in the egg yolks and the condensed milk to coil up and bond together. If this was done with normal milk, it would simply curdle. The add sugar separates the protein strands preventing them from bonding too tightly and becoming curdled. Keeping this in view, what happens if you overcook key lime pie?
When a key lime pie is overcooked, it loses its creamy texture and turns spongy. Remember to only cook the pie for 15 minutes.
Also, how do you set key lime pie? Let the crust cool for at least 10 minutes before adding the filling. This will give it some time to firm up and it will hold together much better. If you don't have any key limes, regular lime or lemon juice will work fine! In order to properly set up, this pie needs to chill in the refrigerator for at least 6 hours.
People also ask, what do you do if your key lime pie doesn't set?
Even with the protein coagulation firming up the filling with the addition of lime juice, a key lime pie often still doesn't hold up when sliced. A quick bake at 325°F (163°C) completely remedies that problem. The proteins will set up just enough to give you clean edges with every slice.
How do I thicken my key lime pie filling?
Using a wire whisk, combine condensed milk and non-dairy whipped topping. Slowly add in the juice, mixing while you add it in. The juice will cause a chemical reaction to take place and the mixture will thicken. You want to whip it to a thick consistency but not over mix, because that will break the chemical reaction.
