Recipe: Formula for Making Gallons of Breakfast Cocoa

  •  ½ a pound of Walter Baker & Co.’s Cocoa,
  •  1 ½ gallons of water, hot,
  •  1 ½ gallons of milk, hot.

This should not be allowed to boil. Either make it in a large double-boiler, or a large Saucepan or kettle over water. Mix the cocoa with enough cold water to make a paste, and be sure it is free from lumps. Heat together the milk and water, and pour in the cocoa; then cook at least an hour, stirring occasionally.
