This three-ingredient version of a Midori Sour combines sweet Midori liqueur with lime juice and egg whites. It's a delicious and refreshing summertime sip (and also perfect for St. Paddy's Day!)
Start out by making your lime peel garnish. Use a vegetable peeler to peel a whole lime in a spiral, keeping the peel unbroken the whole way.
Use a sharp knife to cut off the edges of the lime spiral to make a clean edge.
Set the garnish aside and add lime juice, egg whites and Midori to a cocktail shaker.
Add ice to the shaker and shake for 15-20 hard shakes. This will dilute and chill the drink.
Strain the ice out of the liquid, discard the ice and then do a dry shake (without ice). This will develop the foam from the egg whites. You can shake without ice until the foam is formed, or you can use an electronic milk frother for a few seconds.
Pour the foamy liquid through a fine mesh strainer and into your serving glass.
Add the garnish to the glass and serve immediately. You can optionally squeeze a piece of lime peel over top of the glass to get a nice boost of lime aroma.
