We being less cachaça than Scotch drinkers, I made the ratio 4:2 instead of the called-for 5:1. Suited us fine. But I WILL try the original recipe next time. And thanks; would never have come up with this on my own!

Simon, you have outdone yourself--I see 18 cocktails I want to try immediately!
Will summon patience and method, and enjoy the fruits of your labor. Thank you.
