As befits a seasonal restaurant, Fish & Game in Hudson, New York, publishes a quarterly newsletter that highlights the ingredients, the people and the ideas that influence the cooking and drinking that goes on in within its walls. The just-issued fall newsletter features a look at the F&G farm in nearby Claverack, a profile of the baker whose bread baskets are often a highlight of any meal there, and some tanatalizing recipes, including this earthy mezcal-based cocktail, which makes for a tasty tipple in any season.
