What it tastes like
The citrus acidity leads, smoke dominates the nose and it wears a foam cap.
The technique
Shaking. Anything with juice, syrup, egg white or cream gets shaken: the shaker chills the drink and adds roughly 20% water, and that water is what takes the edge off. Twelve to fifteen seconds, until the tin frosts over. Under-shaking leaves the drink harsh because it never got enough dilution.
Glass and ice
A heavy-bottomed, wide old fashioned glass. Wide enough for one large cube, which is the point: a big cube has less surface area, so the drink gets cold without getting watery.
Ingredient notes and substitutes
Mezcal
The Mexican spirit whose smoke comes from roasting the agave in a stone pit. It can stand in for tequila, but the smoke walks over everything else; starting half and half is the balanced move.
Simple syrup
One part sugar to one part water, stirred until it dissolves — no need to boil it. Keeps a month in the fridge. No syrup? Use the same amount of honey, loosened with a little water.
Fresh lime juice
Freshly squeezed lime. Bottled lime tastes cooked and flat; one lime gives about 30 ml. If you have none, half lemon and half grapefruit juice comes closest.
Ginger syrup
Ginger syrup — grated fresh ginger steeped with equal parts sugar and water, then strained. In a pinch use ginger beer, but then cut the sugar elsewhere in the recipe.
Egg white
Egg white adds texture, not flavour. Shake it first without ice (a dry shake), then again with ice. The vegan swap is chickpea water, in the same quantity.
Chocolate bitters
Cacao-nib bitters. Not sweet, and not to be confused with chocolate liqueur; it adds a dry cocoa depth to whiskey and rum drinks.
The Story
The classic sour template — spirit, citrus, sugar, egg white — applied to mezcal; smoke and cacao are a long-standing pairing in Mexican cooking, which is what the bitters nod to.
