Combine the water, strawberries, sugar, and lemon juice in a large saucepan on high heat.

Bring to a boil, stirring constantly

After the mixture begins to boil, reduce the heat to low, and allow to cook for up to ten minutes, stirring occasionally. As the strawberries soften, use your spoon to break them in pieces.

Remove from heat. Using a strainer, pour liquid into a bowl ensuring to press as much juices through strainer with wooden spoon. Dispose any of the solid strawberries leftover from mixture, and return liquid to pan on low heat.

Meanwhile, whisk the cornstarch with 3 tablespoons of water in a small bowl. Pour into the simmering pan of strawberry juice.

Increase heat to high, and continue to whisk the mixture until it thickens into a glaze (approximately 3-5 minutes).

Remove glaze from heat and cool completely
