Ingredient Steps 4 Video Recipe
- Isabella grapes
1 kg
- granulated sugar
1 kg
- agar agar thickener
10 g
- water
3 tbsp
- Wash grape brushes thoroughly.
- Carefully separate all the berries from the stalks, discarding the rotten and mashed, and put them in the dishes in which the jam will be prepared.
- Pour all the sugar in the container with berries according to the recipe and immediately put on medium heat for cooking.
- Stir sugar for even distribution over the berries and continue stirring until juice begins to stand out. During this boiling time, the dense peel of the grape berries will have time to soften well and “give” the pectin syrup.
- After the juice is allocated, and the syrup boils, it is necessary to reduce the heat to a minimum and cook the berries for another 10-15 minutes.
- With this method of cooking, the jam is quite liquid. To thicken it, you can use a natural thickener of plant origin agar-agar. Take 10 g of agar-agar (1 standard package), pour it into a separate small bowl, fill with three tablespoons of water and leave to dissolve and swell.
- To get rid of the seeds, the berries cooked with sugar in a hot state are wiped through a metal colander with a small cell or a sieve. If the sieve is small in diameter, then the procedure is performed in several portions. As a result, grape bones and peel remain at the bottom of the sieve.
- Grinded grapes are again sent to the container for cooking. At this stage, finished agar agar is added to it. In order for the thickener to dissolve well, you can pour a little mashed grapes into the dishes with it and mix thoroughly, and then pour it into a pan with berries. Put the dishes on medium heat and cook for 5 minutes, during which the thickener will completely dissolve.
- Pour hot grape jam into sterilized jars and cover with lids for storage.
