Within last hour of lamb being ready is time enough to start on the rest. Boil potatoes, carrots, peas and pamphrey in salted boiling water in their own pots and turn down when ready. All will be done within half an hour. Add 1 tsp sugar to carrots and simmer if you like them sweet. For the roasties, deep fry in 180 degrees vegetable oil for 2-3 minutes then put into oven to keep warm if needed.
