2 Tablespoons of Robinson's barley flour.
1 Tablespoon of sugar.
1 Saltspoon of salt.
1 Cup of water (boiling).
1/2 Cup of rich milk.
Whites of three eggs.
Mix the flour, sugar, and salt in a saucepan with a little cold water. When smooth and free from lumps pour in the boiling water, slowly stirring meanwhile to keep it smooth; then set it on the fire to simmer for ten minutes, continuing the stirring until it is thick. To prevent burning, draw the pan to the side of the stove, unless the fire is very slow, for barley is a grain which sticks and burns easily. At the end of the ten minutes put in the milk, and strain all into a clean saucepan, through a coarse strainer, to make the consistency even. Beat the whites of the eggs until light but not stiff, and stir, not beat, them into the pudding, making it thoroughly smooth before returning it to the fire. Cook for five minutes, stirring and folding the pudding lightly until the egg is coagulated. Then pour it into a china pudding-dish. Serve cold with sweet cream. This is good for one who is just beginning to eat solid food.
