The rose hips must be nice and ripe, but still firm. They are dried and then cleaned with a cloth, a slice is cut off at the top where the flower was, and the rose hips are then freed from all seeds using a small, appropriately sized piece of wood. For 1 pound of fruit, you cook 1 pound of sugar in 200 grams of white wine vinegar, skim it well, cook the fruit until soft, remove them with a slotted spoon, place them in jars, cook the juice into a thin syrup, and then pour it lukewarm over the fruit.
