Fresh Strawberry Sauce

1 pint fresh strawberries, hulled

¼ cup white sugar, or more to taste

2 tablespoons water

½ teaspoon balsamic vinegar

2 tablespoons water

1 teaspoon cornstarch

Combine strawberries, sugar, 2 tablespoons water, and balsamic vinegar in a saucepan and bring to simmer over medium heat.

Reduce heat to medium-low, cover, and simmer for 15 minutes.

Whisk 2 tablespoons water and cornstarch in a small bowl.

Whisk cornstarch mixture into strawberry mixture. Cook, stirring constantly, until mixture thickens, 1 to 2 minutes. Remove from heat.

Transfer mixture to a blender and puree until smooth.
