What are the Carbs in Lemons?

The lemon curd used in this lemon mousse recipe uses 1/2 cup lemon juice to make an entire batch. For 1/2 cup lemon juice, there are 10 net carbs.

This recipe only uses 2/3 cup for the entire recipe which means each serving of mousse only has around 3 net carbs.

Curious About Lemon Nutrition Facts?

Not only are lemons a great way to add tangy flavor to your recipes, they are very rich in vitamin C. In addition, they’re a decent source of potassium and vitamin B6.

According to this article found on Healthline, “Drinking lemon water may decrease stress, enhance immune function, help prevent anemia, reduce your risk of kidney stones, and protect against several diseases. “

How to Get the Perfect Lemon Flavor

I used 2/3 cup of the lemon curd in this recipe and I feel that it has a great balance of sweetness and tartness. But if you prefer less tart, use 1/2 cup of the curd. If you like more lemon flavor, use 3/4 cup instead. 

If you’re not sure, start with 1/2 cup of the curd, mix everything together and taste the mousse to see how you like it. That way you can add more curd, if the lemon flavor isn’t strong enough for you.

Tips for Making the Best No Bake Cheesecake Style Lemon Mousse

Mixing up the Mousse

Be sure not to over mix your heavy cream or you will end up making butter!  Making butter is honestly just that easy, in fact I have made butter several times using my food processor.  But for this mousse, you simply want whipped cream, not butter.

For mixing, I find my hand mixer works perfectly.  Alternatively, you can use your stand mixer instead or even whisk by hand.

Substitutions for Low Carb Lemon Mousse

If you don’t have Swerve Confectioners, you can use powdered erythritol instead.  If you happen to have Swerve Granular on hand, you can powder it yourself using a coffee/spice grinder.

If you’re not a big fan of cream cheese or if you want to reduce the carbs, you can substitute the cream cheese with Mascarpone cheese. Mascarpone has the same consistency as cream cheese, but is incredibly low in carbs and has a milder flavor.

I actually use it in so many of my recipes, sweet and savory, including fat bombs, mousse, cupcake frosting and I even use it to thicken gravy and sauce!  It’s one of my very favorite ingredients, because it is so versatile!

Different Ways to Serve Keto Cheesecake Mousse

You can serve up this mousse any way you like and it will be perfect. I served in martini glasses, because I think it gives an elegant touch. I also garnished with some freshly grated lemon zest and a slice of lemon.

These also make great low carb mini desserts for a party!  You can serve your guests this mousse in little shot glasses.  You can easily pipe them out using the tip of your choice and garnish with a fresh berry, sprig of mint, or lemon zest and a lemon slice.

Can You Use These as Fat Bombs?

Absolutely!  You can also prepare smaller portions to use as fat bombs and freeze in small containers.  Once the mousse fully sets, you can scoop out little balls using a cookie scooper and freeze them for later.  If you do this, you can get at least 15 or more servings and that will give you around 15g of fat and just over 1 carb each, not to shabby!
