Are There Any Substitutes I Can Try?

The Key Lime Pie recipe uses ingredients that are readily available to you.

In the off chance that you may be unable to get your hands on any of the ingredients, here’s a list of ingredients that you may use as substitutes:

Graham Crackers: Oreo biscuits, digestive biscuits, Bastogne, Speculoos cookies, or any other crumbled cookies are alternatives to graham crackers.  

Key Lime:  Regular Persian limes in the same quantity as key lime work just as well in the recipe.

Condensed Milk: Cook eggs over simmering water to a point that it coagulates. You may also add corn-starch or dissolved gelatin, to the coagulated eggs instead of condensed milk.

Vegan Substitutes: Substitute the eggs in the recipe for sour cream, and a mixture of corn-starch and water.

It is also essential to use freshly squeezed lime as opposed to the bottled one and refrigerate the pie overnight to ensure that the pie has set properly before serving it.

Serving Ideas and Suggestions 

Since this recipe is a basic Key Lime Pie recipe you can tweak it a little to fit your taste.

Some of my personal favorite additions: powdered cinnamon, coconut whipped cream, fluffy meringue made using egg whites, or the cream of tartar; to augment the flavor of the pie.

Word of caution, be careful while whipping the eggs, over-whipping as this may cause the pie to be runny.

Another trick that helped me reach the desired consistency is to refrigerate the batter overnight, in order to dissipate the air from the batter.

To check the pie doneness, touch the center of the pie with your finger; if it is slightly jiggly, you’re all set because as the pie cools it will solidify further.

  1. Melt the butter in the microwave at 30 second intervals. When the butter is melted, mix in the graham crackers.
  2. Line the bottom of the springform pan with a round parchment paper. Spray the paper and the sides of the pan with nonstick cooking spray.
  3. Use a heart shaped mixing spoon or a spatula to push down the graham cracker crust along the bottom and sides of the pan. Place the crust in the pan while you mix up the key lime filling for this instant pot desserts recipe.
  4. Use a medium-size bowl and blend the egg yolks and sugar for the key lime pie. Blend on high for 3 minutes. The eggs will be light and fluffy.
