I'm enjoying something close to the drink @Ed Hamilton suggested. I say close because while I have a couple different bottles of Ed's rums, it never would occur to me to stock 86 proof Demerara. I mean, what's the point? So I used the juice of one humongously large navel orange, pimento dram, and generous ounce and a half of Hamilton 151.
To my taste the result was far too sweet. So I topped the tumbler up with lime juice. The tartness was now just right. However the beverage was too weak. So I poured in a lot of 151. I do not pretend I measured.
Now I have something worth making again!
