We used this recipe from Allrecipes.com:
16 ounces fresh strawberries, hulled and large berries cut in half
2 tablespoons balsamic vinegar
1/4 cup white sugar
1/4 teaspoon freshly ground black pepper, or to taste
Place strawberries in a bowl. Drizzle vinegar over strawberries, and sprinkle with sugar. Stir gently to combine. Cover, and let sit at room temperature for at least 1 hour but not more than 4 hours. Just before serving, grind pepper over berries.
It was super easy! Also a relatively healthy dessert if you don't have it with vanilla ice cream, but in my mind, that's like having bubble tea without the tapioca. Unacceptable.
