Moscow Mule
Vodka, lime and ginger beer. A deliberate 1940s marketing invention that turned out to be a genuinely good drink.
Mojito
Rum, lime, mint and soda — built in the glass, and ruined more often by over-muddling than by anything else.
Paloma
Mexico’s actual favourite tequila drink. Grapefruit, lime, salt — lighter and more drinkable than a margarita.
