Puree or mash 1 cup of the strawberries and strain through a fine mesh strainer. (See notes at end of recipe).
Slice the remaining 1 cup of strawberries, saving 4 with stems to garnish the glasses if desired.
Pour 1 TBSP of the juice into the bottom of a champagne glass.
Add a few strawberry slices to the glass.
Fill glass with sparkling wine. Stir lightly to combine.
Garnish with a whole strawberry.
The simplicity of this recipe is dependent on the season and ripeness of your fresh strawberries. If you do not have strawberries at the peak of ripeness: puree the strawberries with 1 TBSP of sugar and a squeeze of lemon juice before straining.
