"An ice cream laboratory guide by W. W. Fisk and H. B. Ellenberger" is a scientific laboratory manual from the early 20th century. It introduces the principles and practice of ice cream manufacture, aiming to teach consistent quality through standardized methods, controlled processing, and systematic evaluation. The book outlines essential equipment and safety, then moves through step‑by‑step laboratory exercises that cover standardizing mixes (using Pearson’s rectangular method), testing fat by modified Babcock
procedures, and managing salt–ice temperatures. It classifies products—plain/Philadelphia (vanilla, chocolate, fruit, nut, bisque), cooked/French (parfaits, custards, puddings), sherbets and ices (water and milk sherbets, punches, lacto), and mousse—providing working formulas and directions. It explains stabilizers (gelatin, powders, gum tragacanth) and their preparation; details freezing technique, measuring and improving “swell,” and proper hardening (salt‑ice and cold‑room methods); and shows how to make bricks and moulded novelties. Advanced experiments test how fat level, binders, milk solids‑not‑fat, pasteurization, emulsification, homogenization, cream aging, mix temperature, and freezing time affect texture, overrun, and flavor. Quality control includes score cards for judging, bacterial counts, and gelatin testing, with final assignments for plant visits and student‑devised receipts.
