Heat the white wine until it simmers.
Weigh 700g of sugar and take 2 tablespoons of it, which you should mix with a sachet of Vitpris. Set aside the rest of the sugar for later.
Add this mixture to the wine and bring to a boil, cooking for one minute.
Add the remaining sugar and boil again, then cook for 3 minutes.
At the end of cooking, use a skimmer to remove any surface impurities.
Use a ladle to spread the jelly into jars up to the rim, then seal them.
The jelly will be ready after a few days and can be served with foie gras, cheeses or terrines.
