Grape Fruit Egg
Same as Egg Phosphate only use Grape Fruit Syrup. Invigorating and most delicious.
This is a cross-reference rather than a standalone formula: it sends you to the fountain's Egg Phosphate and swaps the flavoring syrup. Understanding what it assumes explains both the drink and why it cannot be served today.
- What Egg Phosphate meantIn period fountain practice the base drink was typically a whole raw egg with flavoring syrup and a dash of acid phosphate, shaken with cracked ice, strained, and filled with carbonated water. Proportions varied from book to book. In every version the egg was raw; it was never heated at any stage.
- The raw egg is the problemA shaken, iced, uncooked whole egg is exactly the preparation most associated with Salmonella in shell eggs. Chilling and acidity do not make it safe, and drinks like this were marketed as strengthening and nourishing, which put them in front of exactly the people least able to tolerate an infection.
- Acid phosphateNot an archaic mystery: a dilute solution of phosphoric acid with calcium, magnesium and potassium salts, sold to fountains for its dry, tart bite. It is still manufactured for cocktail and soda work. A "dash" came from a dash bottle and was not a fixed quantity; modern practice generally uses something in the region of a quarter to half a teaspoon.
- Grape fruit syrupA fountain syrup, meaning grapefruit juice or extract carried in a heavy sugar syrup. Fountain syrups were markedly sweeter and less perishable than juice, so swapping in fresh juice at the same volume gives a thin, sour drink.
- Fountain measuresFountain syrup was dispensed by pump, conventionally about one ounce per stroke, into a soda glass; glass sizes varied by house. A single serving is one drink.
- If you want the flavorA grapefruit phosphate without the egg is a straightforward, well-documented fountain drink. For any egg-containing version, use a current recipe built on pasteurized eggs.
Egg drinks were a staple of the American soda fountain from the 1880s through Prohibition, sitting on the menu somewhere between refreshment and medicine; the words "invigorating" and "nourishing" appear constantly beside them, and druggists sold them to customers who would not have called themselves ill but wanted building up. The fountain was attached to a pharmacy, and its vocabulary of phosphates, bromides and beef-iron-and-wine tonics reflects that. Grapefruit is the telling detail here: commercial Florida groves expanded sharply around the turn of the twentieth century, and the fruit moved within a generation from a curiosity to a syrup a soda man was expected to stock. Its bitter edge suited the acid phosphate well, which is likely why the compiler thought the combination worth a line of its own rather than leaving it buried in the syrup list.
