Glossy strawberry filling with fresh berries, sugar, lemon and cornstarch; ideal for cakes, cupcakes, and pastries.

# What You’ll Need:

→ Fruit

01 - 2 cups fresh strawberries, hulled and diced

→ Sweeteners & Thickeners

02 - 1/3 cup granulated sugar
03 - 1 tablespoon lemon juice
04 - 2 tablespoons cornstarch
05 - 1/4 cup water

# Directions:

01 - In a medium saucepan, add diced strawberries, granulated sugar, and lemon juice. Gently stir to ensure strawberries are evenly coated.
