Frozen raspberry mousse (adapted from Bon Appetit)
2 1/2 cups frozen raspberries, mostly thawed
1 cup powdered sugar
1 tbsp kirschwasser
1 1/2 cups heavy whipping cream
1/3 cup sour cream
Place raspberries, sugar, and kirschwasser in a blender and blend until very smooth. In a large bowl, whip heavy cream with an electric mixer until it holds stiff peaks. Add sour cream and beat just to combine. Gently fold in raspberry puree. Don't worry if you don't get it all the way blended. The little white ribbons are pretty. Eat some now if you want. Pour the rest into parfait glasses (I used a combination of wineglasses and teacups) and freeze. I used 6 glasses and put a hearty 6-oz helping in each glass. Let it thaw in the fridge for a couple hours or on the counter for 20-30 minutes before eating.
