N2O Ramos Gin Fizz

Ingredients

Method

Combine all the ingredients (except the seltzer) in an iSi whipper; don’t add any ice. Seal and shake for 20 seconds. Open, add five 1-inch ice cubes, then seal tightly once again. Charge with an N2O cartridge, then shake for 10 seconds. Release the first burst of pressure into a cocktail shaker or other vessel, then turn the canister all the way upside down and dispense the cocktail into a large glass. Let settle for about 1 minute. Carefully add the cold seltzer, pouring it down a spoon to ensure that it goes directly to the bottom of the glass and lifts the foamy cocktail above the rim of the glass. No garnish. This technique can be applied to any cocktail containing proteins that will bond around air when agitated (eggs and cream, for example) to make a frothy drink.
