If anyone is interested, I can provide full exact recipe but in a nutshell:
Lamb shoulder cut into chunks (not too generous per person) browned and removed to a casserole/baking dish.
Then add chopped onions and garlic, fry for a minute then add about a teaspoon each of cumin and coriander, then a bit of flour, which once absorbed pour in (slowly) one cup cup stock and a tin chopped tomatoes and half a cup wine (which I'd added together). When boiling, add a tablespoon of honey, a tablespoon of tomatoe paste, a stick of cinnamon and a couple of bay leaves.
Pour over the lamb with one small chopped and peeled butternut, cover and put in oven at 160 for 75 minutes. Then open, stir and put in a tin of drained chickpeas and cook again for 30 minutes.
Oh my word. Meat was tender. Sauce was sticky and delicious. And definitely felt that the 380g of meat could easily have done three people rather.
[the butternut almost disappears, so if you prefer chunks I guess you could put it in with the chickpeas and cook for a bit longer]
