1Begin by heating your pan over medium to high heat and add some oil. Add the pork and brown all over. Remove with a slotted spoon and set aside. Add the onions and cook until translucent. Add the garlic and cook gently for a few minutes.
2Add the chorizo, potatoes and paprika. Stir well for a few minutes. Add the sherry, stock and wine and bubble for a minute.
3Return the pork to the pot and add all the other ingredients. Bring to the boil and simmer, covered, until pork is tender, about 1 hour. Remove the lid towards the end to thicken the sauce. Would also be easily adapted for a slow cooker.
