If using mutton, put the meat into a bowl with the lemon juice or vinegar, 3 tablespoons of the olive oil and a pinch of salt. Leave overnight in the fridge, then rinse under running water, pat dry, and cut into chunks. This is just to take some of the gamey-ness from the meat.
Make slits in the meat and insert some of the parsley and garlic into each slit. Have the flour ready on a plate. Season the mutton or lamb with salt and dust with flour.
Heat the remaining olive oil and the garlic oil in a large pan, then put in the meat and brown over a medium heat. When the lamb is well browned, add the onion and cook for a few minutes until translucent. Add the white wine and bubble up until the alcohol has evaporated, then add the stock. As soon as this boils, add the broad beans and cook for about 1-1½ hours, adding a little water (or more stock, if you have any left) from time to time as needed, until the meat is tender and the sauce has thickened. Drizzle with a little extra virgin olive oil.
