In a blender, combine the strawberries, lemon juice, vinegar, and mint leaves in batches. Cover and process until blended. I think it tastes great right away, but refrigerating for a while probably lets the flavors meld. Garnish with addition strawberries, mint leaves, or a drizzle of some really good balsamic vinegar. A fruit infused balsamic such as raspberry or strawberry, is very nice to use.
What a choice...
