Pretty good - I cut Campari to 1/2 oz and upped blood orange to a full 1 oz. based on previous comments. Still needed something, so I floated 3/4 oz. Taylor's 10 yr Tawny Port on top. That did the trick! — ★★★★
Have to try it. Source calls for only 1/4 ounce campari.
Lime pushes out the more delicate flavors of the blood orange, and the Campari and Triple Sec don't change that. I'd forego the salt rim in the future and perhaps up the blood orange and forego the Campari. — ★★
