Hull the berries by removing the green cap. Place the strawberries and the sugar into a food processor or blender, and blend until smooth. Reserve ½ cup of the resulting puree.
12 ounces fresh strawberries, ½ cup sugar
In a medium-sized bowl, beat the whipping cream until stiff peaks form. Then gently fold in the strawberry puree.
1 cup heavy whipping cream
Distribute the reserved strawberry puree into two serving glasses and then top with the strawberry mousse. Garnish with fresh sliced strawberries if desired.
extra fresh strawberries for garnish
Notes
Frozen strawberries can be used instead of fresh. Let the strawberries thaw in the fridge before blending them. This will give the mousse a smoother consistency.
Store leftover mousse covered with plastic wrap for up to 4 days in the fridge.
Additional garnish ideas: extra whipped cream or a few sprigs of fresh mint.
No need to add sugar to the whipping cream - the sweetness of the puree is sufficient. The whipped cream's purpose is to make the mousse smooth and light.
Variation: Swap out the strawberries for another berry or fruit or melted chocolate to create different flavored mousses. (You can mix and match as well! For example, fold melted chocolate into one half of the whipped cream and strawberry puree in the other, then layer into the serving glass to create a Neapolitan or dark chocolate strawberry mousse.)
