Whey
Put one pint of skimmed milk into a clean saucepan and heat to a temperature of 100° F. (lukewarm). To this milk add 2 teaspoonfuls of liquid rennet, essence of pepsin, or 2 junket tablets, stir until well mixed, and allow to stand at room temperature (70° F.) until firmly jellied. Break up with a fork until it is finely divided, strain through thicknesses of cheesecloth; return the fluid part to the stove and raise to a temperature of 150° F. to destroy the rennet left in the whey. The whey is then cooled before it is added to the milk or cream.
Barley Water
| 3% decoction starch[43] |
| 4 rounded tsp. barley flour |
| 1 pt. water |
Mix a small amount of the water with the barley flour and put the rest of the water into a clean saucepan and allow to heat; when boiling add thin barley mixture, stir thoroughly, and allow to boil 20 minutes; remove from stove, measure, and replace with hot water that which was lost through evaporation to make up the original pint; strain through two thicknesses of cheesecloth.
Oat Water
| 4 rounded tsp. oat flour |
| 1 pt. water |
Mix and proceed as in making barley water.
