Just a hair too sweet for me, but the blackberries added a fun little component. If you want a fresh cocktail that's not too fruity and still full bodied, this one's for you :)
Loved this. Taking the gimlet cue a bit further used a split of lime cordial (per Morgenthaler) in lieu of simple and fresh lime juice, which gave it a slightly more grippy character. Fantastic for a hot afternoon doing nothing.
