Wash the currants and remove the stalk using a fork; Drain in a colander.
Put the fruits in a saucepan and mash a little. Add the preserving sugar, vanilla sugar, lemon + salt and bring to the boil.
Press the mass through a sieve, bring to the boil briefly and cook on a low level while stirring for about 2-3 minutes, then pour directly into glasses.
(Attention: boil the jars beforehand and close them immediately after filling)
Turn the closed jars upside down for approx. 5 minutes, then turn them over and let them cool down (the lid must pull in so that it can be kept longer)
Tip: instead of pressing the currants through a sieve, you can of course boil them in a juicer if you have one. It`s a little easier and the yield is a little more.
I`ve got 8 glasses, but that depends on the size of the glasses.
