Margarita
Tequila, lime and orange liqueur, with salt on half the rim
The classic tequila sour: blanco tequila, fresh lime juice and Cointreau with a touch of agave, shaken and served with salt on half the rim.
Country
3 drinks are tied to United Kingdom. The label on each says how: where it began, what the country is known for, what people drink there, or where the origin is disputed.
Associations are editorial judgements. The evidence link shows the source used.
Not an origin claim. Difford's credits London bartenders in the mid 1990s, Dick Bradsell in particular, with reviving the stirred, fruit free Old Fashioned before that style returned to American bars. The relation records the revival, which rests on Difford's own account rather than on a primary document.

Difford's points to a British ancestor: the 1937 Cafe Royal Cocktail Book by Tarling prints a Picador with the same tequila, Cointreau and lime proportions as today's Margarita. No one claims the drink was invented in Britain, only that its formula was in print there before the name existed. Listed as contested to show the print record, with low confidence on any British origin.

The first printed recipe, in Robert Vermeire's London book of May 1922, says the Sidecar was first introduced in London by MacGarry, and Harry MacElhone's 1922 ABC of Cocktails credits Pat MacGarry of Buck's Club. Difford's reads the record as a London creation around 1919 to 1922 that Paris made famous. Two capitals, two bartenders who worked together, one unresolved claim.
