In a mixing glass, add the sweet vermouth and bourbon, fill with ice, stir lightly, and strain into an Irish Coffee glass. Pour the bitters-flavored cheese cream over the back of a barspoon to float over the cocktail. The cheese cream should easily pour over the spoon and fill the entire surface area of the glass. Sprinkle pink salt across the top.
Bitters-Flavored Cheese Foam
For one serving, make the bitters-flavored cheese foam in a small bowl by adding the cheese foam and bitters and then whisking together.
Cheese Foam
In a bowl add 1/4 cup of the heavy whipping cream to the mascarpone cheese and smash together with a wide rubber spatula until all solids are incorporated into a cream without lumps. Add the rest of the cream and the condensed milk and incorporate. Whip to a consistency that is still easily pourable. If it gets too thick to easily pour, add a bit of cream or milk to thin it out. Will keep in the refrigerator for 3 days.
