Ingredients

  • grated rind of 2 lemons
  • 5 Tbsp. fresh lemon juice
  • 1 Tbsp. lemon extract
  • 1 whole egg
  • 2 eggs, separated
  • 1/2 cup sugar
  • 1 Tbsp. cornstarch
  • 1 Tbsp. cornstarch

Instructions

  1. Combine lemon rind, lemon juice, lemon extract, egg yolks, whole egg, 1/2 cup sugar, and cornstarch in a double boiler.
  2. Cook over hot water, stirring constantly until thickened (about 6 to 8 minutes).
  3. Remove from heat and transfer the mixture to a bowl to cool.
  4. Ensure the mixture is completely cold before proceeding to the next step.

Tips & Substitutions

For a lighter texture, consider folding in whipped egg whites after cooling the lemon mixture. If you don't have lemon extract, you can substitute with an equal amount of vanilla extract for a different flavor profile. Make sure to use fresh lemons for the best taste, as bottled juice may not yield the same brightness. This mousse is a refreshing finish to rich meals or pairs beautifully with Best Ever Pound Cake.

Serving Suggestions

Serve the lemon mousse in individual cups or bowls, garnished with fresh berries or a dollop of whipped cream for added richness. A sprinkle of crushed graham crackers or shortbread cookies on top can add a lovely crunch. This mousse pairs wonderfully with refreshing beverages like iced tea or lemonade, making it perfect for warm weather gatherings.

Storage & Reheating

Store leftover lemon mousse in an airtight container in the refrigerator for up to 3 days. To maintain its airy texture, avoid covering it tightly, which might cause condensation. It’s best enjoyed chilled, so serve it straight from the fridge. Avoid freezing, as the texture may change when thawed.

Frequently Asked Questions

Can I use bottled lemon juice instead of fresh?

While bottled lemon juice can be used in a pinch, fresh lemon juice yields a brighter, more vibrant flavor that is essential for a good lemon mousse. If you must use bottled juice, opt for a high-quality brand that doesn't contain preservatives.

How can I make this recipe dairy-free?

To make this lemon mousse dairy-free, you can substitute the egg yolks and whole egg with a commercial egg replacer or a combination of silken tofu and lemon juice. This will help achieve a creamy texture without using dairy products.

What can I do if my mousse doesn't thicken?

If your lemon mousse hasn't thickened after cooking, it may need more heat or time. Return it to the double boiler and cook a bit longer, stirring constantly. If it still doesn’t thicken, consider adding a bit more cornstarch mixed with cold water to help achieve the desired consistency.
