Fee BrothersLime Bitters

The perfect foil to any rum drink if you're finding it too sweet. Neat or mixed, a drop or a dash will make for a whole different take. I haven't tried other brands of lime bitters so can't compare but I've no complaints so far. No idea why rum and lime pair so well but they've been partners for centuries for good reason. I was a little worried that using lime bitters, instead of just expressing a bit of lime zest/oils, would taste a bit artificial but used in moderation you get the lime zest taste and a balancing bit of bitterness to harmonise things too. It's win win.
