In a saucepan, combine strawberries, sugar, and lemon juice. Stir over medium heat.
In a small bowl, mix cornstarch and water until smooth. Add to the strawberry mixture.
Bring to a simmer and cook for about 10 minutes, stirring frequently, until the sauce thickens.
Remove from heat and let it cool. The sauce will thicken further as it cools.
Serve as desired or store in the refrigerator.
Notes
Use ripe strawberries for the best flavor.
• Mash the strawberries according to your preference for texture.
• Adjust the sugar based on the sweetness of the strawberries.
• Stir constantly while cooking to avoid burning.
• Let the sauce cool before serving to thicken.
