81.—Soda Biscuits.
12½ lbs. of flour, 1 oz. of salt, 6 ozs. of lard, 1 oz. of acid, 1½ oz. of soda, 2 quarts of water. Mix as for Machine Biscuits, break the dough smooth and clear, let it lay for about half an hour, then roll out in large sheets nearly the thickness of three penny pieces, cut out with an oval spring cutter five inches in length and three inches in breadth. The dough must be well made and of a good stiffness. When cut out lay them on top of each other in sixes on carrying boards. Have the oven of a good sound heat and well cleaned out, have a running peel that will hold six biscuits, and run them on the sole of the oven.
