Frozen cranberry and blackcurrant jelly

1. We take cranberries and currants out of the freezer, defrost. Now we need to make berry puree from them, for this we beat them with a blender into a homogeneous mass.
2. Put the berry puree in a saucepan and pour 800 ml of water, after it boils, cook for another 5 minutes.
3. Filter through a fine sieve or gauze, folded in 2-3 layers. Add sugar to your liking and cook the syrup.
4. In a glass of cold water, we dilute the starch and pour it into the syrup, mix it quickly so that there are no lumps. It is not necessary to cook for a very long time, as it began to thicken, we remove the pan from the fire, when the drink cools down, it will become even thicker. To prevent a film from forming on the surface, you can sprinkle sugar on top and cool it under a closed lid. Jelly can be consumed both hot and cold.
