One quart of flour, one table-spoonful of butter, a teaspoonful of
salt, rub these into the flour and turn it on to the moulding board;
turn into it a small tumbler of ice-water; knead the water in little
by little. Then pound it with the rolling pin fifteen minutes, roll as
thin as possible, and cut out as you do cookies; round cutters are the
best for crackers; mark with a jagging iron, and bake ten minutes.
