Pro Tips

Notes
FAQs
How should I store this leftover mousse? Keep the dessert cups tightly covered with plastic wrap in the refrigerator. It stays wonderfully airy and fresh for up to two days when kept completely chilled.
Can I substitute the granulated sugar? Yes, you can swap it for powdered sugar if you want an even smoother texture. If you prefer a lower calorie option, a powdered stevia blend works flawlessly too.
What is the best way to serve this treat? I love serving it very cold straight from the fridge in elegant glass cups. A single fresh raspberry or a sprig of mint on top makes it look totally professional.
Why did my cream curdle when adding the juice? This common mistake happens if you add the acidic lemon juice before the cream has reached soft peaks. Always whip the cream partially before streaming in the tart citrus juice.
Can I freeze this fluffy dessert? I strongly suggest not freezing this mousse because the heavy cream will weep and separate when it thaws. It is best enjoyed fresh from the refrigerator to maintain its beautiful cloudy texture.
