My take on Imbibe’s recipe

Combine in a boston shaker with ice:

• 1.5 oz. bourbon (in this case, Basil Hayden’s)
• 0.5 oz. homemade lavender syrup
• 0.5 oz. fresh squeezed lemon juice

Strain into a collins glass filled with ice. Using the back of a spoon, pour 0.5 oz. of Cynar on top for the float.
