Technique
Chill
To chill a glass is to make it cold before the drink goes in, so a cocktail served without ice stays cold longer.
In practice
Fill the glass with ice and water while you mix, then tip it out just before you strain. Keeping a few glasses in the freezer works too. It matters most for drinks served up in a coupe or cocktail glass.
