We have taken the frangelico down a little bit, and then used a dry oloroso instead of the fino. It keeps the nuttiness, but makes it rounder and slightly less sharp. We used Knightor’s dry vermouth. Next time we’ll try with a palo cortado. I think this is a bit underrated.
Agreed, less liqueur and dry oloroso sherry are delicious. I've amended the recipe accordingly. I also tried with palo cortado but nutty notes were more pronounced and overall cocktail better with oloroso. Many thanks, Nick.
