Sparkling Strawberry-Ginger Lemonade

Place strawberries in a large glass measuring cup; mash with a muddler or wooden spoon until very juicy. Transfer the mixture to a fine-mesh strainer set over a bowl; press firmly to express as much juice as possible. (Save the solids for another use.)

Combine the strawberry juice, lemonade and ginger beer in a large pitcher. Serve over ice in tall glasses. Garnish with sliced and/or whole berries and mint sprigs, if desired.
