Just made this with Amaro Montenegro. I did consider adding black walnut bitters, which with the maraschino might add a chocolate/cherry/ cola vibe that could be interesting. Definitely a drink to muck around with!

Having always used shop-bought cocktail onions for this (fabulous) drink, I'm going to pickle my own - nice little cocktail onions (NOT great big pickling ones) are with your greengrocer right now in the UK. I'm going to use a mix of white wine and rice wine vinegars, with sliced ginger. Some recipes suggest adding chilli, but that ain't
happening. Maybe a little added sugar. I'll let you know how it goes.

Very nice - if you love a Sour, you'll love this.
As an aside, I've not bothered with dry shaking in the past, but thought I'd give it a try. I use a three-part shaker (probably because I'm a philistine), and dry shaking (actually reverse dry shaking) is thus a bit of a palaver. If you're in the same boat, do yourself a favour and try a dry shake rather than a reverse dry shake (check out the Diffords instructional) - it'll make life much easier.

Amazing that this wonderful drink hasn't generated a single comment. I'm currently enjoying a highball comprising 60ml bottled-in-bond Mellow Corn straight corn whiskey, 75ml soda and a twist of lemon. Partner is having a brandy highball. C'mon, show this classic some respect!
