An extremely simple method: place your stock, bacon and thyme in a pan on the hob, bring to the boil and then sprinkle in your finely sliced cabbage. Mix up, put the lid on and boil furiously for 5 minutes. Turn the heat down to a simmer and continue to cook until the cabbage is a pleasure to eat. Top up the stock a little bit if you feel it’s reducing too much. Add the butter, a good glug of extra virgin olive oil, season to taste and serve immediately.
