Shake, Shake, Shake.

This article from Food & Wine provides a professional guide to cocktail shakers. It discusses two types of shakers: the Boston shaker and the cobbler shaker. The Boston shaker consists of two tins that create a seal, while the cobbler shaker includes a cup for ingredients, a cover with a built-in strainer, and a cap. The article also explains the purpose of shaking a cocktail and provides three shaking techniques: the tin-on-tin shake, the short shake, and the hard shake. The information is sourced from The Maison Premiere Almanac. [Extracted from the article]
