Albert Stevens Crockett's original recipe calls for two-thirds genever to one-third sweet vermouth, but this produces an overly dry cocktail so I've upped...
This drink is splendid I made it with Bols Genever and also with Jorgen new style floral genever - it rocks regardless - I made it 2 oz Genever; 1.5 oz Barolo Chinato and 2 healthy dashes of Boker Bitters. Lemon slice and oils as well. Fabulous.
I was in Pittsburgh last month and went to the Wigle distillery. Excellent wide-ranging array of brands; was a bit stunned. Bought a bottle of their 'Dutch-Style Gin'. This has been so far the best cocktail I've made with it. Used a recent (today) purchase of Poli Gran Bassano. What a delightful combo!
