Slice up cabbage leaves and simmer to tender with half an onion with a couple of cloves pushed in and a small bay leaf and a garlic clove. Add a stock cube. Drain (remove onion etc) and put the liquid aside.
I know, it sounds weird - but keep going!
I usually have quite a bit of liquid left - I keep it for other dishes.
Meanwhile, melt a knob of butter, a dessertspoon of plain flour (or cornflour), a good teaspoon of curry powder (I have Madras and used that). Add the liquid to make a stiff sauce. Put the cabbage in the sauce and let it infuse gently. Add a little paprika to taste, if wanted (does taste good without).
The curry sauce is a bit like you get in chip shop sauce, I think?
The cabbage tastes lovely and is tender and juicy. It goes really well with any dry or bland meat or plain meat. I have made it twice now and I think we ate more cabbage than we would have done just plainly boiled!
