Healthy Substitutions

Just like many of our other recipes, we show you how to make simple modifications to your ingredients to make a huge impact on their nutritional values. Key Lime Pie is a refreshing custard pie but it doesn’t have to be a decadent one.

How to Make It

We use simple substitutions to make this pie where you won’t miss a thing! Looking for labels that say “dairy free” or ” low fat” or “zero sugar” is an easy thing to do these days and we utilize that here. Fat free is not a good option as it is usually carb filled, so low fats are better!

Tips and Tricks

Why is the cook time so quick?

The acidity of the lime juice does all of the work here. You only need to get the pie semi set and while it cools for 45 to 60 minutes, it continues to cook and set up.

Can I do this with Lemon?

Yes, for a lemon pie, the method is the same. Just substitute lemon juice and zest and get the same result.

How do I make the Unhealthy version?

That is simple, use whole eggs, full fat sweetened condensed milk and regular cool whip for the pie. The crust can be done with regular sugar and graham crackers. You will not be able to tell the difference!
