Review

This drink benefits from a long, chilling and diluting stir. The result is Martini in style, fruity yet dry.

Variations/similar cocktails

There are numerous blackthorn recipes, but they fall into two camps: one based on Irish whisky with vermouth and absinthe and the other with gin/sloe gin and vermouth. The numbering of the various Blackthorn variations starts in the 1930 Swallows edition of Boothby's World's Drinks And How To Mix Them and continues in his posthumously published 1934 edition, where he adds the Blackthorn No. 5.
Blackthorn No. 1 - sloe gin, rosso vermouth, dry vermouth, aromatic bitters, orange bitters.
Blackthorn No. 2 - sloe gin, rosso vermouth, sugar syrup, lemon juice, aromatic bitters, orange bitters.
Blackthorn No. 3 (AKA Blackthorn Irish) - Irish whiskey, dry vermouth, absinthe, Bokers bitters.
Blackthorn No. 4 - gin, Dubonnet, kirshwasser, orange bitters.
Blackthorn No. 5 - gin, sloe gin, dry vermouth, lemon juice, sugar syrup, aromatic bitters.
Blackthorn (English) - gin, sloe gin, rosso vermouth, dry vermouth, orange bitters, aromatic bitters.

Very pleasant. I only had the rather mediocre Weis Kirschwasser, but can see this angling for an extra hall a star with a nice one. Good call on the extra Dubonnet compared to Boothby.

An underrated classic, called Blackthorn No. 4 in The World's Drinks And How To Mix Them (1934). I prefer with 30ml Dubonnet and a dash of Orange Bitters. Fantastic.

Many thanks, Jason. I've renamed this cocktail to follow Boothby's convention and will take a fresh look at proportions.
