When to shake
Shake when the drink includes citrus, egg, cream, or anything you want fully emulsified. Air and ice do the work — you get chill, dilution, and texture in one motion.

Core method · Shake hard · 10–15 seconds
Chill, dilute, and integrate citrus, egg, dairy, or any cloudy mix.
The big idea
A hard shake chill-dilutes and aerates in one motion — use it whenever citrus, egg, or dairy needs full integration and a lighter texture.
Shake cloudy or acidic builds; stop when the tin is painfully cold (~10–15 seconds).
Pack with ice — sparse ice melts too fast and warms the drink.
Fine-strain drinks served up to catch chips and pulp.
Air from shaking emulsifies egg and brightens citrus; that texture is intentional.
Spirit-only classics usually prefer a stir for clarity and denser mouthfeel.

Pack the tin
Ice to the brim — sparse ice melts and warms.
Shake hard
10–15 seconds, loud rattle, until the tin hurts.
Strain promptly
Fine-strain if it's served up.
Fill the tin with ice, seal hard, and shake vigorously for about 10–15 seconds. Aim for a loud, even rattle — not a gentle rock.
Strain promptly. If the recipe is served up, fine-strain to catch chips and pulp.
In the glass
Read the drill, then make the drink once focusing on that cue — repetition beats another paragraph.

Rum
Shake until the tin hurts. Make one at ~8 seconds and one at ~15 — taste warmth versus water, then lock in the painfully-cold cue.

Whiskey
Citrus plus optional egg. If you add white, dry-shake first; the wet shake is what chills. Foam should sit, not scum.

Tequila
Hard shake, fine-strain if it’s up. If it tastes dull, check the lime before the tequila.

Gin
Raspberry and egg want a vigorous shake. Thin pink liquid means the foam stage was rushed.
