A warming winter stew. Warning! this is a stew...this means the slower it is cooked, the yummier! Nicola is a good yellow fleshed potatoe, or ask your grocer for one that has good flavour and will stay together when cooked. Chop the potatoe, pumpkin and sweet potatoe into chunks the same size, and the parsnip and carrot the same size, a little smaller.
