3/4 oz Blandy's 5 Year Sercial Madeira (*)
3/4 oz Grapefruit Juice
1/2 oz Luxardo Maraschino Liqueur
3-4 Mint Leaves
Shake with ice and strain into a cocktail glass. Float a lightly spanked small mint leaf.
(*) Another dry style like Verdelho would work here, but sweeter styles like Bual and Malmsey would shift the balance.
