Review

This delicious cocktail is sadly often overlooked in favour of the bourbon-based Whiskey Sour.

Depending on the peatiness of the whisky, bitters aren't strictly necessary in a Scotch Sour. However, as David A. Embury says in his 1948 The Fine Art of Mixing Drinks, "Two dashes of Angostura to each drink constitute a pleasing addition to this drink. Lime juice may be used in place of lemon, but, to most tastes, lemon combines more pleasingly with whisky than does lime. Scotch or Irish may be used in place of rye or bourbon, but the smoky taste of Scotch does not combine pleasingly with citrus juices."

While I'm usually in full agreement with Embury, I vehemently disagree with his opinion regarding the pairing of peaty Scotch and citrus. And for evidence to back my argument, I call The Penicillin Cocktail. As for bitters in this sour, I prefer the complex, liquorice-led notes of Boker's Bitters to Angostura Aromatic Bitters.

We serve this, and all of our Sours, in a Coupe glass...nothing kills a Sour more quickly than dilution. And we include in the garnish a dash of Peychaud's Bitters...tasty and pretty.

Agreed - looks better in a coupe to boot.

To my taste, excellent, even with a very basic whisky. A good way to make people that don't like whisky enjoy it.

Should the `How to make` section include fine-straining given the egg?

The foam from the egg will pass through the fine strainer, but the strainer will catch any curdled egg, and the chalaza and ensure the foam has a light texture.

I think this is my favourite sour. Everything is perfectly balanced with the taste of the Scotch Whisky in the spotlight.
Not sure why, but this did turn out to more foam than the other sours we have mixed.
Definitely a perfect cocktail for any time and any season.

Mine produced more foam with less egg white than my normal whiskey sour. I also agree with other comments (and Simons) that with a Smokey whiskey there is no need for bitters. Finally, with aged liquors (rum, whiskey, brandy, etc) I prefer Peychaud bitters ver anga stour a.

Really good. Proud of myself for being able to get the foam this time as well! Used Chivas Regal 12 Year Old!

Made it with our cheaper William Lawson's. While it had a strange tang at the start, the egg white still renders it as a luxuriant drink with a nice sour balance.

No bitters at all?

Not traditionally but down to personal taste. I've added a quote from Embury recommending 3 dashes of Angostura.

The whisky sour (with bourbon) has three dashes of Angostura bitters in its recipe. However, David Embury suggests that Peychaud combines better than Angostura with scotch (in his recipe of the Bobby Burns). So, I tried adding three dashes of Peychaud in a Scotch Sour. You should try it too, in my opinion... ;-)
This cocktail is also great without any bitters.

I made the same formula with Bourbon. It was tasty
