Lime Mousse Ingredients

Believe it or not, you only need four simple ingredients to make this mousse recipe.

• Cream Cheese: This is what gives your mousse a little thickness and slight tang. You don’t need much, but it really brings things together.
• Sweetened Condensed Milk: The key ingredient to help tone down the tartness of the lime juice. It also is where the sweetness comes in to play.
• Key Lime Juice: Squeezing key limes to get enough juice can be quite the task, but is well worth it. However, you can also use bottled juice. This is most likely located in the baking aisle of your grocer.
• Heavy Cream: To get the light and fluffy texture, we’re whipping cream to stiff peaks. This is going to add air into the mousse providing that classic texture.
• Phyllo Dough Cups: Optional, but oh-so adorable. This is our favorite way to serve this recipe. They make for the perfect bites sized mousse dessert.

What Is The Difference Between Limes And Key Limes?

First off, you will notice that regular limes, also known as Persians, are much larger than their Key Lime cousins. Besides the difference in size, what are the other main differences between the two? We dived into comparing and found that key limes have a more bold floral aroma, tend to be a little more yellow vs green, and pack a tart punch. That bold flavor is exactly what you need in this lime mousse recipe.

That being said, you can always substitute regular limes if you aren’t able to find Key Limes in your store. You will still get a wonderful citrus flavor. It will just be slightly less bold.

Best Key Lime Mousse Recipe

Like the ingredient list, there aren’t many steps in this recipe. It’s as simple as measure, mix, and eat.

1. PREP: Read through the recipe carefully and pre measure the ingredients. Whip the cream until stiff peaks form and set aside.
2. MIX: Combine the cream cheese, sweetened milk, and lime juice in a bowl. Beat with a whisk, or hand mixer, until fully combined. Fold in the whipped cream.
3. ENJOY: Serve immediately or chill until ready to serve.

This recipe is such a light and fun flavor. While we decided to serve as bite sized favorites, you could easily serve this mousse in a dish with a spoon.

Helpful Tools

• Hand Mixer: While this definitely can be mixed by hand, a hand mixer (affiliate) will make it come together quickly and lump free.

• Airtight Container: Saving the mousse for later? Be sure to invest in a quality airtight container (affiliate) to help keep it fresh longer.
