1 Tablespoon of arrowroot.
1 Saltspoon of salt.
1 Scant teaspoon of sugar.
1 Cup of hot water.
1 Cup of milk.
"Wet the arrowroot with the sugar and salt in two tablespoons of cold water, then pour on the hot water, stirring constantly. Boil it for twenty minutes, then add the milk and bring just to the boiling-point. Strain it, and immediately serve.
Arrowroot is almost pure starch. Its grains burst at 140° Fahr.; therefore, if boiling water be poured upon it, it will form into lumps which will have to be strained out, and thus a part of the material will be lost; hence the necessity of wetting it in cold water to reduce the temperature so that it may be stirred smooth before the lumps form.
Milk is changed by long boiling, and loses some of its agreeable taste; it is better, therefore, not to put the milk into the gruel until after the flour has been thoroughly cooked in the water, thus preserving its natural flavor.
Arrowroot gruel may be flavored with cinnamon by boiling a half square inch of cinnamon bark in the water with which the gruel is made. Nutmeg, lemon juice or peel, and sherry wine may also be used; but the sherry should be avoided unless the gruel is to be served cold.
