Pro tip: The best way to get that froth on a cocktail is to dry shake your egg white first, then add ice and shake.
Start this cocktail by making your favorite mulled wine. We tend to like the NY Times recipe. Add all of your ingredients to a shaker, dry shake for 15 seconds, and then add ice, and shake for another 30-seconds. Strain and pour into a coup glass. Grate a little nutmeg on top to garnish.
