⭐ Why You’ll Love This Recipe
I tend to use egg whites like crazy, so I’m always looking for ways to use up the leftover yolks. That’s where this Yuzu Chocolate Mousse recipe comes in! Made with Valrhona’s Yuzu Chocolate, this bright and creamy chocolate mousse has a vibrant citrus twist. It’s the creamiest and dreamiest mousse I’ve ever tasted!
French chocolate mousse is traditionally made by mixing flavor into whipped egg whites, yielding a light and airy texture. I went against tradition in this recipe and folded whipped cream into melted yuzu chocolate and whipped egg yolks at the end to give each bite a fluffy, creamy, and dreamy texture!
❓What is yuzu?
Yuzu is an incredibly fragrant citrus fruit mainly farmed in Japan, Korea, and China. Like lemon and lime, yuzu is very aromatic but also packs a sour punch. I like replacing lemon juice with yuzu juice in my recipes (like these yuzu raspberry macarons) when I have it on hand because it adds a pleasant and unique tartness.
Get to know the ingredients needed to make this classic French dessert:
- Yuzu Chocolate - Using yuzu chocolate instead of milk or dark chocolate adds a bright citrus flavor to this classic French dessert. If you can’t find yuzu chocolate, feel free to use another kind of high-quality baking chocolate instead (not chocolate chips).
- Butter - Use quality unsalted butter here.
- Egg yolks - The trick is using older (NOT expired), room temperature egg yolks. The yolks are heated in a double boiler to ensure they’re safe to eat.
- Sugar - Granulated sugar adds sweetness and helps the whipped yolks develop stiff peaks.
- Heavy cream - To make whipped cream, which is folded into the mousse at the end.
- Lemon zest - This gives each spoonful a burst of vibrant flavor.
📖 Step by Step Instructions
Step 1: Melt the chocolate and butter. Combine the yuzu chocolate and butter in a heatproof bowl and place it on top of a pot of simmering water. Stir until the chocolate and butter are melted. Set the bowl aside, but leave the water simmering.
Step 2: Whisk egg yolks and sugar. Whisk the egg yolks and sugar together in another heatproof bowl on top of the simmering water. Continuously whisk until the mixture becomes opaque and stiff.
Step 3: Stir mixtures together. Add the chocolate-butter mixture to the bowl with the egg-sugar mixture and stir to combine. Let it cool to room temperature.
Step 4: Combine with whipped cream. Beat the cream until soft peaks form. Next, whisk a ¼ of the whipped cream into the mousse. Gently fold in the rest until fully incorporated.
Step 5: Chill to set. Transfer the mousse into ramekins and refrigerate until the mousse has set.
Step 6: Garnish and serve. Garnish each portion with a dollop of whipped cream and lemon zest, then enjoy!
👩🏻🍳 Expert Tips
- Enhance the flavor - Add a ¼ teaspoon of vanilla extract to intensify the indulgent flavors.
- Don’t skip the chill - As tempting as it may be to dig in right away, mousse always needs to chill and set in the fridge for at least 1 hour before serving. Otherwise, it will have a loose, pudding-like texture.
