We use the juice as a flavouring in some dishes, and also add the lemons to boiled dishes. Cheap cuts of pork can have a 'old' smell about them, and we use pickled lemons to take away that smell. When adding these pickled green lemons (or limes if you prefer to call them that), to boiled dishes, it is important to only boil them for 5 minutes or so. Any longer and the lemon will break open, making the stock bitter. You don't want the lime to open, only whole limes should be used in stocks.
