Sauté the onions in the oil for 15 min until soft. Fold in the sugar and caramelize with the onions. Season vigorously with pepper, salt, cumin and thyme.
Add the fruit vinegar. Pour in wine and clear soup and simmer for 10 minutes.
Stir the soaked gelatine into the onion vegetables until it melts. Season if necessary.
Place onion mixture in ramekins, cool and refrigerate for about 1 1/2 hours.
Turn out the onion jelly and cut into pieces.
Serve with light roasts (e.g. roast pork, roast veal).
Our tip: Use sweet red wine for a sweet note and rather dry wine for flavorful, spicy dishes.
