Spotted Dick

Instructions:

Put the flour and salt in a bowl. Add the suet, currants, sugar, lemon and orange zest. Pour in 150ml milk and mix to a firm but moist dough, adding the extra milk if necessary. Shape into a fat roll about 20cm long. Place on a large rectangle of baking parchment. Wrap loosely to allow for the pudding to rise and tie the ends with string like a Christmas cracker. Place a steamer over a large pan of boiling water, add the pudding to the steamer, cover and steam for 1 1/2 hours. Top up the pan with water from time to time. Remove from the steamer and allow to cool slightly before unwrapping. Serve sliced with custard.
