I have a old book, Irvin S. Cobb's, Own Recipe Book, published just for "drink recipes" in 1937...
This old book has been around, on the front cover there is a stamp..."Toohey's Liquor Store, 209 N Union St., Phone 3522 Lic. L. 4422"
This is from that book:
Yet consider how starkly elemental were the beginnings of this fine art: The earliest chronicled American potation was called Flip. The formula required that there be a stirred into a pitcher of strong home-brewed, or amateur beer enough crude molasses to sweeten the beer and give it something to fight with. To the above conglomeration, for harmony's sake, was added rum in the proportion of one full jorum of the rum for each drinker, thus conferring general authority on the whole. And after that, as a dainty final stroke, the mess was heated by plunging into it a red-hot poker. And then---believe it or not, dearly beloveds,---and then our sturdy brass-lined forbears actually drank it...
They drank it for breakfast!
The rest of the forenoon being spent in songs and folk-dancing.
This old book has alot of "old time" recipes in it Mint Julep...is the most discussed and debated recipe. There are several...and they firmly state that fresh "mint" is used...Not peppermint
