Add about ¾ of the stock. Cover and leave to simmer gently. After 15 minutes check it and stir in the rest of the stock if necessary.
Spoon the filling into the marrow. You might not be able to fit all the stuffing in. Return the stuffed marrows to the oven and cook for another 20 minutes. The extra stuffing can be served alongside the marrows or for anyone who doesn't like marrow and just wants the stuffing.
