Wash the tomatoes, dab dry and cut into cubes. Cut dates a little smaller
Put tomatoes and dates in a pot and bring to the boil. Stir in jam sugar, salt, honey and vinegar. Let everything simmer for 6-8 minutes at high heat while stirring
Pour the jam into 5 clean jars with twist-off lids, close them immediately and place them on the lid for about 5 minutes. Turn over again and let it cool down
