Try Darina Allen's traditional Irish bacon, cabbage and parsley sauce

Traditionally, the cabbage was always cooked in the bacon water. People could only hang one pot over the fire at a time, so when the bacon was almost cooked, they added the cabbage for the last half hour or 45 minutes of cooking.
The bacon water gives a salty, unforgettable flavour, which many people, including me, still hanker for. You will need to order the loin well in advance, especially with rind on.
