Mousse is a great dessert because it satisfies a sweet tooth without being too heavy after dinner. Last year, I made a couple different key lime pies.
Both pies were good, but I don’t always feel like making a pie crust. I thought about just whipping up some of the filling and pouring it into a pie plate.
Since it has been a while since my last blog post, I decided to try a new recipe. I created a key lime mousse recipe using the chocolate mousse recipe as a guide.
This time, I wasn’t sure if using juice in place of cocoa was going to thin out the mousse, so I added three tablespoons of ground lecithin granules to help thicken it.
I know that lecithin is often used as a substitute for egg yolks and yolks are used to help thick things like pudding so I gave it a try. The mousse came out light and airy with a great key lime flavor.
I don’t really think the lecithin granules are necessary in this key lime mousse recipe. Just whipping up the cream with a little dissolved gelatin is a better way to thicken.
I’ll likely omit the lecithin next time since it’s a specialty type ingredient. It’s best to keep recipes to simple every day ingredients if possible.
So, I’ve marked the lecithin as optional in this low carb key lime mousse recipe. Leaving it out will result in a smoother product.

Made this for Easter. It was so good! I left out the lecithin. Thank you. I so enjoy your recipes.
Lisa MarcAurele says
Lecithin isn’t needed and I should just remove it from the recipe as it’s a specialty ingredient that isn’t easy to find.
Emily Kemp says
Sounds so yummy, great idea to use key lime pie flavours in a mousse!

Curious about what size is a single serving? half cup?
Lisa says
I put them in 1 cup serving dishes and they filled them about 3/4 full.
Jeanette says
This looks so yummy! Where do I find lecithin granules and do I grind them myself, or buy them that way.
