Clean and dice 2 cups strawberries, add 1 cup to a bowl, mash, and set aside.

In a medium saucepan, stir together the sugar and cornstarch. Add the water and 1 cup of mashed berries.

Over medium heat, bring the mixture to a boil, stirring constantly. Stir in food coloring, if desired.

Cook and stir 3 minutes or until thickened. Remove from the heat and stir in the 1 cup of diced strawberries.

Transfer to bowl and let cool for 10-15 minutes.

Serve immediately or store in an air tight jar or container for up to a week.
