Lemon Mousse Tips

Can you make lemon mousse without eggs?

Traditional lemon mousse needs eggs to achieve the light, creamy texture. Although they aren't mousse, lemon marmalade or lemon jam can be whisked until thinned out, then folded into whipped cream for a tasty lemon dessert if eggs aren’t available. This vegan chocolate mousse is also a great option.

What can you serve with lemon mousse?

To complement the creamy texture, a thin, crisp cookie pairs beautifully with lemon mousse.

How long will lemon mousse last?

Simple lemon mousse lasts up to 3 days in the refrigerator. It might begin to separate after that. A tightly covered container is the best option for storing. Check out this article on how to store every type of leftover food
