Green Holland

Smoky mescal with menthe & lemony hints
1 12 oz Mezcal, Del Maguey
1 12 oz Green Crème de Menthe
34 oz Lemon juice
1 oz Heavy cream
1   Egg yolk
Shake all ingredients vigorously with ice, strain into a frozen coupe glass. Garnish with a cherry.
THE NAME: "green" is for the creme de menthe. My pal Mike G. said that the lemon juice + egg yolk reminds him of Hollandaise sauce, so that's where "holland" comes from.
