Fry the bacon until crisp and then set aside. Finally fry the onion, cloves, garlic and chilli until soft. Return the sausages, black pudding and bacon to the pan and add the beans, treacle, paprika, ketchup, mustard and vinegar. Stir well and simmer for 20 minutes.
Meanwhile, fry the new potatoes in the butter with the chilli and paprika, then add the lemon juice.
Spoon the potato slices over the top of the sausage and bean mix. Bake in the oven for 20 minutes, finishing under the grill for a crispy topping if necessary.
