roduced "Soynog", the earliest known soy-based non-dairy and vegan eggnog based on soy milk and tofu (added for thickness). It was renamed Lite Nog in 1982 and Tofu Nog in 1985.
Health and safety
Most homemade eggnog recipes have historically included raw eggs. While the alcohol added to many homemade eggnogs is a bactericide, eggnog freshly made from raw eggs that are infected with salmonella and not heated can cause food poisoning. In 1982 most of the residents and staff of a nursing home in the U.S. became ill with salmonellosis, and four died. The cause was almost certainly an eggnog made on the spur of the moment, with some cases caused in a secondary outbreak caused by food being handled later by people with contaminated hands. A later publication of the U.S. Food and Drug Administration (FDA) stated that the alcohol in eggnog is not sufficient to sterilize contaminated eggs. Using commercial pasteurized eggs or heating the milk-egg mixture sufficiently can make the drink safe; one recipe calls for heating the mixture gently, without boiling, until it thickens enough to "coat the back of a spoon."
However, aged alcoholic eggnog becomes sterilized even if made with contaminated eggs. Aging alcoholic eggnog—sometimes for as long as a year—has been said to improve its flavor significantly, and also destroys pathogens. The Rockefeller University Laboratory of Bacterial Pathogenesis and Immunology carried out an experiment in 2010 where salmonella was added to a strong eggnog which was refrigerated and stored; the beverage still had dangerous levels of salmonella a week later, but it was all gone within three weeks. A concentration of at least 20% of alcohol (about the same amounts of alcoholic spirits and milk or cream), and refrigeration are recommended for safety.
For concerns about the safety of selling products made from raw eggs and milk, the U.S. FDA has changed or altered the definition of eggnog a number of times towards artificial replacements for the large number of eggs traditionally used. FDA regulations (as of January 2015) require eggnog to contain at least 1% egg yolk solids and at least 8.25% milk solids. Some recipes for homemade eggnog call for egg yolks to be cooked with milk into a custard to avoid potential hazards from raw eggs.
TIME magazine states that individuals should be aware of the alcohol content of eggnog, from a responsible drinking perspective. CNN states that some 19th century American eggnog recipes called for significant amounts of alcohol; one recipe "calls for three dozen eggs, half a gallon of domestic brandy, and another half-pint of French brandy." The high alcohol content of "...colonial eggnog inevitably led to problems. In 19th-century Baltimore, it was a custom for young men of the town to go from house to house on New Year’s Day, toasting their hosts in eggnog along the way. The challenge: to finish one’s rounds still standing."
The most notable case of alcohol problems associated with the drink was the Eggnog Riot at the United States Military Academy in West Point, New York, on 23–25 December 1826. Alcohol possession at the academy was prohibited, along with drunkenness and intoxication, both of which could lead to expulsion. By 1826, concern had been raised that drinking was starting to get out of hand among the 260 cadets at the academy. The cadets were informed that, due to the alcohol prohibition on the site, their Christmas eggnog would be alcohol-free, prompting the decision by cadets to smuggle liquor into the academy. Gallons of whiskey were smuggled into the barracks to make eggnog for a Christmas Day party. This led to "...a drunken free-for-all. Windows, furniture, and crockery were smashed; banisters were torn from walls, fights broke out. One eggnog-addled cadet tried, but failed, to shoot his commanding officer." The incident resulted in the court-martialing of twenty cadets and one enlisted soldier. Neither the young Jefferson Davis nor Robert E. Lee, who were in attendance, was found guilty of any offences or expelled.
