Equipment
Method
- Combine strawberries, sugar, and lemon juice in a saucepan. Cook over medium heat until fruit breaks down.
- Stir frequently as mixture bubbles. Mash slightly for smoother texture if desired.
- Mix cornstarch with water separately, then add to pan. Stir until thick and glossy.
- Simmer until jam reaches desired thickness. It should coat the spoon without running.
- Cool completely before using. Filling thickens further as it rests.
Notes
For thicker jam, cook longer or add more cornstarch. For softer consistency, reduce thickener. Chill before assembling to prevent slipping layers. Add vanilla or spices for variation. Store refrigerated up to one week or freeze for longer storage.
