The Sidecar in Spirits & Cocktails Posted April 17, 2014 I don't make many sidecars, but taking the BarSmarts course and browsing through Essential Cocktails by DeGroff, I thought I'd make a classic tonight. I noticed that both Regan and Bartender's Choice both have the same ratio for a Sidecar (3:2:1) so I thought I'd give it a go 1.5 oz Ferrand 18401 oz Cointreau (seems a bit insane!).5 oz lemon Sugared rim, being a traditionalist and all... To my surprise, sugared rim aside, it is not a particularly sweet drink. I guess Cointreau is not nearly as sweet as simple syrup, and there is a distinct tart, even bitter quality from the lemon. Overall pretty good, though I think a 8:3:3 ratio might give it the kick that this lacks.Also worth remembering Cointreau is 40% abv so you may also find the bitterness emphasised by that in some way, though more likely it's the bitter orange peel. Usually I'll cut down on the Cointreau a little and compensate for sweetness with a small dash of gomme. Works doubly well if there's some orange blossom water in the syrup.
