Pour in a saucepan one pint of cold water and half a pound of granulated sugar ; place it on a hot stove. Dilute an ounce of corn-starch in a cup with a gill of cold water, and when the water in the saucepan is boiling, add it to it, stirring well for two minutes with the pastry-whip. Take off from the fire, then add immediately half a gill of kirsch, and mix again for one minute ; strain through a fine sieve into a sauce-bowl, and serve very hot with the pudding.
