Hot Fernet Flip

Combine Fernet Branca, Allspice Dram, gin, honey syrup, and egg yolk in a shaker.

Shake vigorously without ice until the mixture is well combined and frothy.

Slowly whisk in hot water, stirring continuously to maintain the froth.

Carefully pour the mixture into the center of a heat-resistant glass to avoid residue on the sides.

Garnish with a dusting of freshly ground nutmeg.
