I’ve made it plenty of times without the jam, still tastes great, just a little more tart. You don’t have to thaw the frozen berries. This recipe makes a thin sauce, but if you would like it thicker and gooey, combine a teaspoon of cornstarch to a teaspoon of cold water in a separate small bowl. Then add this to the recipe and cook until bubbly. I’ve also tried using frozen strawberries- just as good.
Raspberry Sauce
1 (12 oz.) bag of frozen raspberries
½ cup sugar
1 teaspoon vanilla
2 teaspoons cornstarch mixed in 1 teaspoon cold water
In a small saucepan over medium heat, bring frozen berries to a slight simmer, DO NOT MIX (keep the fruit together as much as possible). Strain out seeds with a fine mesh sieve. Return sauce back to stove and add sugar and vanilla, simmer for a minute until dissolved. Add cornstarch mixture, simmer for one minute until thickened. Remove from heat and allow to cool. Store in refrigerator.
