How to make
The blackcurrant is cleaned and washed. Put it in a baking pan and pour the sugar. Leave it for a day in the refrigerator, or outside.
The next day, take it out and leave it for another hour. Then bake it in the oven at 150-160°C, until the desired thickness is obtained.
Add the citric acid and after five minutes take it out and fill jars with a screw on lid and turn the hot jars upside down. They should be left like that for a night.
The jam is not sterilized.
The blackcurrant jam is ready.
