Made a pair for my better half and I. Perfectly highlight the grapefruit side of the Campari with a solid backbone from the Pierre Ferrand 1840. Unfortunately, I'm almost out of it. For two and adjusted to the size of my glasses:

• 3oz Pierre Ferrand 1840 cognac
• 1 1/2oz Campari
• 1 1/2oz Lemon juice
• 1/2oz Rich syrup 2:1

Combine all the ingredients in a mixing glass with ice and stir until chilled. Strain in a cocktail glass, express the oils a lemon over it zest and garnish.
