Halve the red cabbage, remove the damaged leaves. Cut into the finest strips with a slicer or a food processor. Put in a sieve and rinse briefly with warm water.
Heat the clarified butter in a roaster, add the onions and apple wedges and sauté until light yellow while stirring. Add the sugar and let it caramelize for about half a minute, stirring again and again. Put the red cabbage together with the lemon juice in the roasting pan and cook for 5 minutes, stirring, until it collapses a little. Add the vinegar, water, red wine, bay leaves, salt and the currant jelly and mix.
Place the roaster with the lid in the oven preheated to 150 ° C and cook for 45 minutes. Then take it out, mix the cornstarch with a little water and bind the red cabbage with it. Season with cinnamon, pepper and cloves and let simmer for another half a minute.
It is best to prepare red cabbage the day before; the more often you heat it up, the better it tastes. It is also ideal for freezing.
