For the Filling
In a small saucepan, combine the raspberries, sugar and lemon juice. Use a spoon or potato masher to break the raspberries down and release their juices then use an immersion blender to puree.
If you'd like a seedless filling, strain the mixture in a fine sieve and return to saucepan.
Heat mixture over medium high heat until it reaches a low boil.
In a small bowl or cup, combine the water and cornstarch. Add to raspberry mixture and stir quickly to thoroughly combine. Continue to heat the mixture at a low bowl; mixture should thicken and begin to look glossy. Cook 2 minutes longer, stirring constantly to avoid scorching on the bottom. Cool completely.
