I love this one; I've had it in my rotation for a while now. Almost too good to share. 
Warday's (Harry Craddock) with Tanqueray London dry gin, Martini Gran Lusso vermouth, Daron XO calvados, green Chartreuse. (I use the ratios from the Bartender's Choice app).
It's a great winter-to-spring transition drink with the mix of gin and apple brandy (I used calvados) as the base. There is something great about the interplay of the botanicals in the juniper-forward gin with the Chartreuse, and then the sweet vermouth & calvados giving it depth and warmth.
