Like a subtly fortified white wine. Attractively delicate flavours with beautiful balance. Dry, spicy, underpinned by sweetness. Characteristically of its creator, despite being a modern invention it has the feel of a classic. Highly recommended, especially for white wine and Calvados fans.
Instead of 3/4 oz Lillet Blanc try using 1/2 oz each of Lillet Blanc and Tempus Fugit Kina L'Aero d'Or. Excellent! (I also used Santa Fe Spirits Apple Brandy, but availability may be limited in some areas.)
