- 3 cups fresh or frozen strawberries (thawed if frozen), mashed with a fork 750 mL
- ¾ cup granulated sugar 175 mL
- 3 tbsp cornstarch 45 mL
- ½ cup cold water 125 mL
- 3 drops red food coloring
- 2 tsp freshly squeezed lemon juice 10 mL
- In a heavy saucepan, heat strawberries and sugar over medium heat, stirring constantly, until juices are released and begin to boil.
- Remove from heat and, using a fine-mesh strainer set over a bowl, press pulp through to strain seeds from mixture. Return juice to saucepan and bring to a boil over medium heat.
- Meanwhile, in a small bowl, whisk together cornstarch and cold water to make a milky substance. Pour into boiling juice, whisking to incorporate. Cook, whisking, until no longer cloudy. Add food coloring and cook, whisking, until mixture is thickened, about 3 minutes. Remove from heat. Whisk in lemon juice.
- Transfer to a bowl and let cool. Cover and refrigerate until chilled prior to using.
