Begin by hydrating the gelatin in ¼ cup of cold water. Sprinkle the gelatin evenly over the water and let it sit for about 5 minutes until it becomes soft and spongy
In a blender, combine the peeled and diced mango, fresh lemon juice, skim milk and powdered stevia or sweetener of your choice. Add the hydrated gelatin to the mixture and blend until you achieve a smooth and homogeneous texture.
Using an electric mixer or a whisk, beat the cold evaporated milk in a chilled bowl until it thickens and forms stiff peaks. This step adds a creamy and airy texture to the mousse.
In a separate bowl, beat the egg whites until stiff peaks form. Gently fold the beaten egg whites into the whipped evaporated milk, creating a light and fluffy base for the mousse.
Gradually incorporate the mango mixture into the mixture, gently folding it in with a spatula or whisk. Ensure that all the ingredients are well combined.
Divide the mango mousse mixture evenly among serving glasses or ramekins, filling them up to about three-quarters full. This allows room for the mousse to set and expand slightly. Carefully transfer the glasses to the refrigerator and allow the mango mousse to chill and set for a few hours, preferably overnight, or until it becomes firm and holds its shape.
Once the mango mousse has fully set, remove it from the refrigerator and garnish with a slice of fresh mango, a sprig of mint, or a dusting of powdered sugar if desired. The chilled mousse is now ready to be served and enjoyed as a refreshing and delightful dessert.
