Right. This is from a lovely lovely book called Roast Figs, Sugar Snow by Diana Henry, and I'm trusting she doesn't mind me reproducing it here as I am also heartily recommending the book.
Serves 6:
500g haricot beans, soaked overnight.
500g salt pork or unsmoked bacon in the piece (but we just used bacon as that's all we had!)
4 cloves garlic, finely chopped
6 tsp tomato passata
3tbsp maple syrup
3 tbsp molasses (we could only find molasses sugar, but it tasted fine)
3tbsp dry English mustard
3 tbsp cider vinegar
2 bay leaves
salt and pepper
6 cloves
2 onions, quartered
3 tbsp roughly chopped fresh flat-leaf parsley.
Drain and rinse the beans and put them in a large, heavy bottomed casserole. Add enough water to cover them by about 5cm and bring to the boil. Boil hard for 10 mins, then turn down heat to a simmer, cover and cook for about an hour, until the beans are tender but not completely soft. Check the water to ensure they don't boil dry.
Preheat oven to 140C/275F/GM1
Ciut pork or bacon into 5 cm cubes. Add to beans along with garlic, passata, maple syrup, molasses, mustard, vinegar, bay leaves and pepper (don't add salt yet as it depends on how salty the beans become because of the salt pork or bacon). Stick cloves into quartered onions and add them too. Add more water if necessary, so that the beans are covered. Replace lid, put casserole in oven and bake for 2 hours. Remove lid, stir and put the casserole back in the oven for another hour to brown and thicken. Check occasionally to check that beans aren't becoming too dry. Taste for seasoning and stir in parsley.
We had these with baked potatoes, and they were gorgeous. BabyHab hoovered them up. It is quite salty because of the bacon/pork, so I wouldn't give them to little ones frequently. I'm going to experiment on producing a less salty version.
