How to Make Lemon Curd for a Tangy Keto Lemon Cheesecake Mousse
To give your cheesecake mousse that extra zing, homemade lemon curd is key. In a small saucepan, whisk together fresh lemon juice, egg yolks, sweetener, and a bit of lemon zest over medium heat. Stir constantly until the mixture thickens, then remove from heat and fold in butter for richness. Let it chill before folding into your mousse mixture.
This step ensures your cheesecake lemon mousse benefits from both smooth cream cheese and bright, silky lemon curd. The result is a low carb lemon cheesecake mousse with depth and complexity in every bite.
How to Whip Cream Cheese & Whip Cream for Fluffy Keto Cheesecake Mousse
Achieving the perfect texture for your keto cheesecake mousse requires proper whipping techniques:
- Beat the Cream Cheese: Use an electric mixer to whip your softened cream cheese until light and fluffy—this prevents lumps in the final mousse.
- Whip the Cream Separately: Chill your whip cream bowl and beaters, then whip the whip cream to soft peaks. Overbeating will turn it grainy.
- Fold Gently: Combine the whipped cream cheese and whip cream with your lemon curd and lemon juice and zest using a spatula. This gentle folding keeps the airy texture of a true mousse dessert.
By following these steps, you ensure your keto lemon mousse is fluffy, light, and delightfully smooth.
How Long Should You Chill Your Keto Lemon Mousse?
Chilling is crucial for the mousse to set properly. After assembling your cheesecake mousse, transfer it to serving dishes or a large dish and cover. Refrigerate for at least 4 hours, though overnight chilling yields the best results. This resting time allows the flavors—fresh punch of lemon flavor and creamy keto cheesecake to meld and intensify.
If you’re in a hurry, pop it into the freezer for about 2 hours, checking frequently. But for a perfectly silky keto lemon cheesecake mousse, patience is rewarded with a dessert that holds firm yet melts in your mouth.
