How to make Lemon Mousse Pie.

Tips for making the best mousse pie.
This recipe includes a pie crust that should be made ahead of time.
The pie crust will need to be frozen in order to set (this is a no-bake recipe).
More helpful tips for you.
- This is a lemon pie that needs lemon juice to get the flavor. You can easily make this into a lime pie by substituting lime juice.
- I am providing you with a pie crust recipe. Feel free to use your own recipe for pie crust or a premade low or no sugar one.
- Whipping the ingredients is essential to getting that perfect 'mousse'. I suggest that you use a stand mixer outfitted with a whisk attachment if possible.
How to store mousse pie.
Lemon mousse pie should be stored with a tented covering and refrigerated. To make a tented cover, place a few toothpicks into the topping around the surface of the pie. Then, loosely drape plastic wrap or aluminum foil over the toothpicks. When properly stored and refrigerated, lemon mousse pie should keep for up to a few days.

Great taste! Will definitely make again. Please clarify the amount of heavy whipping cream to be used. I did have trouble with it โnot settingโ

Good to hear that you enjoyed this recipe. Working with heavy whipping cream can be tricky. You need to use heavy whipping cream that is cold. It also can help to use a cold bowl and beaters/whisk. Some people like to start the whipping slowly and then increase the speed to medium. Lastly, to get the texture needed in this recipe, it is best to not whip more than four minutes as over-whipping will cause the the peaks to become lumpy. Hope this helps! ๐
Please let me know if you make this again!
