What each ingredient does

Maple syrup: Provides the main sweetness and the maple flavor.
Egg yolks: Thicken the mixture as they heat and add richness and body.
Heavy cream: Whipped to trap air, giving the mousse its light, airy texture.

The step that matters

Cook the yolk mixture until thickened. Egg yolk proteins set gently around 65 to 70°C, which thickens the custard. If it gets too hot or cooks too fast, the yolks scramble and turn grainy, so a double boiler and steady stirring help keep it smooth.
