Ohh yesss.
Made one today. Stew, a bottle of stout (cairngorm black gold), 2 knorrs stock pots, a dash of Worcester sauce, in the slow cooker for 7 hours, cooked off some Lincolnshire sausages, chopped them up, mixed them through, then a slab of pastry on the top, put in the oven till the pastry was golden brown, served up with roast potatoes. Lovely.
