SEPARATE egg yolk from egg whites. Place egg whites aside, and add yolk to shaker tin. Add all other ingredients to shaker tin, and SHAKE with ice. Strain...
Why separate the white from the yolk? My sister does this. Seems to work just as well if egg is beaten until frothy and the put in the rest of ingredients for a wet and dry shake. Not criticizing, just genuinely curious, sis doesn’t know she’s just following old family recipe
