Slow cook black beans

500g dried black beans
2 large onions, chopped
2 tbsp olive oil
1 tbsp cumin seeds
6 garlic cloves, chopped
1 tbsp lemon juice

Soak the beans overnight. Drain, put in a pan and add enough water to cover. Boil and bubble hard for 10 minutes, then reduce the heat and cook for about 1 and a quarter hours (they might need more water).

Fry the onions in the oil for 10 minutes, add the cumin and garlic and cook for another 2 minutes. Set aside.

Stir the onions into the beans once they're cooked, add the lemon juice and seasoning.

Serve with yoghurt/sour cream/chopped chillies/coriander/whatever else takes your fancy.

*Warning - contains lots of beans and may have after effects*
