  • Delicious with Flor de Caña 4 yr, 2:1:0.75, rich simple (per Pietro Collina)
  • With Havana Club 3 year, this (2:1:0.5) is one is among the very best cocktails. A classic for a reason.

  • Starting point: 2 oz rum:3/4 oz lime:1/4-1/2 oz simple. Darker rums go well with demerara or turbinado simple.

This version was originally posed by bschneier. It has been adopted as a Quickstart Classic Cocktail.

According to The Gentleman's Companion vol. 2 by Charles H. Baker Jr. (1939)
"Doctors still thought that a lot of yellow jacket malaria cases came from drinking water and swamp mists. The couldn't turn off the swamp water mists but they knew that diluted alcohol was a disinfectant agent against germs. So they put a little rum in their boiled drinking water. This tasted pretty bad so some bright citizen squeezed a lime into the thing, and added a little sugar to modify the acid. Ice made from distilled water took the topical heat off the thing. The 2 originators were my friends Harry E. Stout, now domiciled in Englewood, NJ and a mining engineer associate Mr. Jennings Cox. Time: Summer of 1898. Place: Daiquiri, a village near Santiago and the Bacardi plant, Cuba. Hence the name "Daiquiri."

Morgenthaler says the best recipe (which he got from Diffords) is: 2 1/2 oz aged rum, 3/4 oz fresh lime juice, 1/2 oz simple syrup

I've tried many variations on quantities and either aged, light or dark rum. It really just falls into what your personal preferences are. I like the aged and light rum variations with same ratios but at 2oz, 3/4oz and 1/2 oz. Another example is that Robert Hess calls for this ratio but inverts the simple syrup to 3/4oz and lime to 1/2oz. Whether Difford's is the best recipe, again, is a matter of taste. Cheers.

I have been loving this lately as 2 oz Probitas, 1 oz 1:1 cold process simple, 3/4 lime, which is basically Sasha Petraske spec. Thanks,  Zachary

Zachary. You mean 1 oz lime to 3/4 oz simple, right? Because that's the Petraske spec and the same they use at Attaboy etc today. 

Yeah, sorry - I don't have my book and had it flipped in my head. Thanks,  Zachary
