Love the Tom Collins? Try its frothy, bubbly cousin, the Gin Fizz. The secret to creating the perfect creaminess and froth is to shake, shake, shake—and then shake some more.
Add the first four ingredients to a shaker and dry-shake (without ice) for about 10 seconds.
Add 3 or 4 ice cubes and shake very well.
Double-strain into a chilled fizz glass and top with club soda.
