Thaw Out Raspberries - Thaw out the raspberries and strain the juice. Add water to the juice in order to get 3/4 cup of liquid.
Cook the Raspberries - In a small saucepan, add the raspberry juice/water mixture, lemon juice, sugar, and cornstarch. Cook the mixture over medium heat, whisking consistently. Once the mixture thickens and begins to bubble, remove it from the heat.
Strain the Mixture - Using a fine-mesh strainer, press the raspberries in and use a spoon to push the seedless pulp through into a bowl. Strain enough to get 1/3-1/2 cup of raspberry pulp. Disregard the raspberry seeds.
Add the Liqueur - Add the strained raspberry pulp and raspberry liqueur to the saucepan. Stir the mixture well and refrigerate it for a few hours or overnight before using it.
