The best cocktail kit should include all of the basic equipment, such as a solid metal cocktail shaker, a single and double jigger, a long mixing spoon or bar spoon, a Hawthorne cocktail strainer, a muddling tool and tongs. These tools should have a good weight and shouldn’t feel flimsy. If you are planning on taking it over to friends, then look out for one in an easily transportable bag or box.
