After playing around with a few different concoctions, I went with Thad and Eric's suggestion of the El Dorado 3 year, but with Erik A's stir-in-cold, simple syrup recipe and ratio. I think it's the best drink I've ever made at home. I can't believe how balanced it is - the cane flavor of the rum with the sweet and sour. Amazing. My wife was blown away. This is a Daiquiri? I'll be making these all weekend, rest assured.
I've learned about how citrus and sugar work together, about different types of rum, and how to make a Daiquiri that works for my household. I'm pumped. Sticking to one drink really works.
