Expert Tips For Making Mousse
Even though this mousse is a simple recipe with just three ingredients (sugar-free chocolate chips, egg whites and heavy cream) it's important to follow these tips for the best results.
- When melting sugar-free chocolate chips, be sure to use a double boiler or metal bowl over simmering water. The water should not touch the bottom of the bowl. A double boiler is used to prevent the chocolate from burning.
- Since this recipe calls for uncooked egg whites, be sure to purchase pasteurized eggs from the store. Uncooked egg whites are typically used in ice cream eggnog, and mayonnaise.
- Let the eggs come to room temperature before whipping according to recipe instructions. This is important step since the egg whites are more likely to reach full volume when whipped (thereby creating a lighter mousse).
- Be sure the mixing bowl and beaters are completely clean and dry before beating cream or egg whites in order to avoid issues when whipping to peaks.
- Whipped peaks should not curve or fall (slightly leaning is normal).
- Be careful to not over whip cream. If you do, it will turn grainy.
- When folding whipped cream and egg whites into chocolate mixture, it is best to use a flat spatula. To fold, simply scoop under the chocolate and then fold over the top of the whipped cream or egg whites. Continue until whipped cream and egg whites are integrated. Do not stir mixture.
