Grape and Walnut Jam

⏱️ Prep: 40 min🍳 Cook: 150 min

Ingredients

Separate and wash the grape berries. Place them in a deep vessel, sprinkle with the sugar and pour over 1 tea cup of water and the vinegar. Set the fruit to boil, stirring the jam and skimming off the released seeds (if any) with a slotted spoon.
When a drop of the syrup, dropped onto a dry porcelain saucer, holds its shape without spreading, add the cinnamon, the cloves and the nuts. Boil the jam for about another ten minutes, then pour it, still hot, into warmed jars.
Close and store in a dark, airy place.
