In scanning my liquor shelves, I conjured up an Scotch abstraction of the Bijou taken in the Caustic Negroni direction. Since Scotch goes well with amari like Sfumato in the Preceptor and Cardamaro in the Great King Street, Green Chartreuse and orange bitters would round out the combination nicely. Moreover, Bijou means jewel, so I dubbed this one the Romancing the Stone after the 1984 romantic adventure comedy.
