I use the recipe in the Larousse bible.
It is just red wine vinegar, peppercorns and bay leaves plus the cabbage.
Boil the wine vinegar, let it cool completely, then pack the cabbage into sterilised jars, layering with a couple of peppercorns and a bay leaf every inch, then pour over the cooled vinegar.
Having been unable to resist opening the first jar after only a week I can vouch for it being very nice. Not as vinegary as some, tho perhaps still vinegary for others. I love it esp with lamb stew <yum>
