1 Tablespoon cornstarch, 3 Tablespoons warm water, 1 Tablespoon lemon juice
Combine strawberries and sugar: In a medium saucepan, add the hulled and sliced strawberries along with the 1/4 cup of granulated sugar. Stir to combine.
1 pound strawberries, 1/4 cup 50g granulated sugar
Cook the strawberries: Place the saucepan over medium heat and cook, stirring occasionally, until the strawberries begin to release their juices and soften, about 5-7 minutes.
Thicken the mixture: Stir the cornstarch mixture again as it tends to settle and Add the mixture to the strawberries. Stir continuously until the mixture thickens, about 2-3 minutes.
Cool the mixture: Remove the saucepan from the heat and let the mixture cool. The strawberry mixture is now ready to be used in your desired recipe, such as a topping for pancakes, waffles, or a filling for desserts.
