Notes
    
          Sorry for the weird volumes - it's technically 7:2:1:1, and Embury says that cocktails are about 2.5 ounces. This is 2.75 pre-chill.

I curated this - a little googling pegged it as an Embury drink so I removed the bitters and changed lemon (from the OP submission) to lime and jiggled the ratio a bit to conform to the book. Thanks, Zachary
