Mix The Flour, Currants And Grated Suet (It Should Have The General Consistency Of Mouse Droppings) Very Lightly By Hand. Moisten With A Couple Of Tablespoons Of Cold Water, Enough To Give A Dryish Pastry Texture. Stir To Bind The Ingredients Together. The Mixture Can Be Put Into A Buttered Basin And Covered With First A Layer Of Foil, Then A Cloth (Tied On With String), But The Usual Way Is To Make A Thick Roll Shape, And Wrap It In Buttered Greaseproof (Waxed?) Paper, And Tie Into A Cloth. Boil In A Lot Of Water For Two To Three Hours On Top Of The Stove, Or All Day If Using A Crock Pot. To Serve, Slice It Into 1" Thick Chunks While Still Hot.
