Highland Morning

For some reason there's a lot of grapefruit juice and scotch drinks. I'm betting this is because grapefruit juice became popular with canning in the early twentieth century. But you'll want to squeeze it fresh because it is less bitter than canned juice. I'm also betting that people who drank scotch the night before needed to re-intoxicate in the morning with a dose of juice in their scotch.

• 1 oz. scotch
• 3/4 oz. Cointreau
• 3 oz. grapefruit juice

Combine all ingredients with ice in a chilled Old Fashioned glass.
