Wash and chop the fruit. Scrape out the vanilla pod and mix with the fruit. Puree everything in a blender or with a hand blender. Mix with the remaining ingredients and bring to the boil, stirring constantly. Let simmer for about 6 minutes.
You can fill a small bowl with about 1 teaspoon of jam in between, swirl it back and forth if the jam is still too runny and continue cooking. If the jam stays rigid, it`s done.
Immediately pour the finished jam into the prepared jars and close. Turn the glasses upside down for 15 minutes and let them cool down.
If you want a fruit spread with pieces, you mix all the ingredients and let them steep for 3 hours. Proceed as described above.
