Heat 2 tablespoons of the olive oil in a wok or similar large pan. Add the 4 whole garlic cloves and the slice of bread and fry over a medium heat for 2 minutes, turning once, until golden. Lift out and leave to drain and cool.

Cut pork into quite large chunks. Season well then dust them in the flour. Add another 2 tablespoons of olive oil to the pan and add the chunks of pork to seal and only lightly colour. Remove to a plate and set aside.

Add the remaining oil to the pan with the onion, chopped garlic, pimenton dulce, thyme and bay leaves and cook gently for 10 minutes until onions are soft and sweet but not browned. Add the wine and stock and bring to the boil, rubbing the base of the pan to release any bits and pieces.

Return the pork to the pan, lower the heat and season well. Cover and simmer gently for 1.5 hours or until the meat is meltingly tender.

Spoon about 16 tablespoons of the sauce into a food processor and add the fried bread, fried garlic cloves, almonds and parsley leaves. Blend to a smooth paste (this is called a picada in Spain). Stir the picada back into the pan, taste and adjust for seasoning, cover then cook for a further 5 minutes which will allow the sauce to thicken.

You could serve the pork and sauce with potatoes or rice.
