Wash and clean the strawberries. Then quarter the strawberries and put them together with the raspberries in a high saucepan and slowly bring everything to a boil. Slit open the two vanilla pods and scrape out the vanilla pulp. Put the pulp in the pot and grind the mixture with the hand blender.
Add the preserving sugar and vanilla sugar to the mixture and bring everything to a boil over medium heat. Let the mass boil for a total of about 2 minutes.
At the same time, rinse the jam jars and lids with hot water and dry the lids. Pour 175 g of hot jam into each jar, screw on the twist-off lid and let it cool down.
