This is the perfect challenge! When you want something “light” and “delicate” but only have one egg and no oven, the answer is a Cloud-Style Vanilla Mousse (similar to a French Crème Légère).
By using that single egg to create a base custard and then folding in some air, you get a dessert that feels like eating a sweetened breeze.
☁️ The “One-Egg Wonder” Mousse
| Ingredient | Amount | Function |
| Egg | 1 large | The yolk adds richness; the white adds “fluff” |
| Milk | 200 ml | The base for your custard |
| Sugar | 2-3 tbsp | To your preferred sweetness |
| Cornstarch | 1 tbsp | To thicken the “pot” without an oven |
| Vanilla | 1 tsp | For that classic delicate aroma |
| Greek Yogurt or Cream | 100g | To fold in for that “no-bake” volume |
🥣 The 10-Minute Method
- The Base: Separate your one egg. In a small saucepan (off the heat), whisk the egg yolk, sugar, and cornstarch together until smooth.
- The Cook: Slowly whisk in the milk. Turn the heat to medium-low and stir constantly. As soon as it thickens into a glossy pudding (about 3-5 minutes), remove from heat and stir in the vanilla.
- The Cooling: Transfer this custard to a bowl and let it cool completely. To speed this up, place the bowl in a larger bowl filled with ice water.
- The “Cloud” Factor: * Option A (Light): Whisk the egg white with a pinch of sugar until it forms stiff, snowy peaks. Fold this gently into the cold custard.
- Option B (Creamy): Fold in 100g of Greek yogurt or whipped cream instead.
- The Set: Spoon into glasses and chill in the fridge for 1 hour.
💡 A Touch of Wit
Because we are using a raw egg white to get that “no-bake” fluffiness (Option A), make sure your egg is very fresh! If you’re worried about raw whites, stick to Option B—the Greek yogurt version—which is just as delicious and adds a nice “tang” that cuts through the sugar.
Peer Correction: Don’t try to add the cold yogurt/whites while the custard is still hot! If you do, the “cloud” will melt and you’ll end up with a sweet soup rather than a mousse. Patience is the only ingredient you can’t substitute here.
🍓 Serving Suggestion
Since this is a very delicate dessert, top it with whatever fruit you have on hand—a few raspberries, a slice of kiwi, or even just a grating of dark chocolate.
