A lot of the vintage tequila cocktails I have been able to scrap together are actually from the Trader Vic’s 1972 revised bartending guide. In fact he has this cocktail in there twice. It’s first referenced as the El Diablo, then the EXACT same recipe is on the next page as the Mexican El Diablo. They are line for line, word for word, ounce for ounce the same. The only difference is one has a straw and the other does not. Not sure if that really counts as a different cocktail but maybe he was trying to pad up his tequila section like me. He must have struggled to find tequila recipes too; There are not that many.
I’m not really one to talk though, all this writing is really hard. Collectively I think I have written about 100 pages worth of single spaced 12 point font information and history for this app, and I know I have a bunch of grammar and syntax errors. So if you find any of those errors… oops, I try to fix them as I find them. I also try to update my histories if I find out any new info.
