I've had several cocktail shakers pass through my kitchen, but I finally found the one I'm holding onto. OXO sent me this shaker last year to try out, and it's been barely put away since. Why? It's truly leakproof (unlike one of my previous shakers), and double-walled, so you can shake until your cocktail is well and truly chilled - without freezing your hand off. (So this is the right shaker for making that Ramos Gin Fizz you've been meaning to try.) When the cocktail is shaken, press the button on top and pour; unless the button is pressed it's airtight. The shaker is generously sized; I make double and even triple batches in it when serving a group. It has a removable gasket that's dishwasher-friendly, too. Great performance; easy cleanup. It's doesn't have the cred of the old-fashioned Boston shaker, but for this cook with small hands and a tendency to spill things, this gets the job done better than anything else.
