This salt air margarita is topped with a later of salty foam that provides just the right amount of saltiness with each tangy grapefruit margarita sip.
Cut the grapefruit in half and squeeze the juice into a large bowl. Strain out any pulp and seeds.
Make the salt foam: Combine all ingredients and blend with an immersion blender until foam forms and volume is about doubled. Allow the foam to sit for about 2 minutes, and then carefully scoop out the foam and spoon over margarita.
Combine all ingredients in a cocktail mixer with ice. Shake, and serve immediately with salt foam on top.
