For the strawberry-cherry fruit spread, wash the jars thoroughly with hot water. Pit the cherries and put them in a pot with the chopped strawberries and heat, add sweetener and stir well.
Finely puree the fruit with a hand blender. Whom pieces in the jam do not bother, can also just mash the fruit.
Then mix 1 heaped tsp (equivalent to 4 g) agar agar with cold water and let it swell. After 2 minutes, mix it into the hot fruit pulp.
Bring the mixture to a boil and simmer for 3-5 minutes, stirring constantly. Then fill the fruit mass into the prepared glasses.
