Not being a big fan of mezcal, we approached this cocktail with reservations. Found it very flavourful and wonderful before dinner. You can taste the smoky of the mezcal, but is not the overpowering flavour of the cocktail which is the rye.
I found even the small proportion of mezcal overpowered the whisky. Will try a smoky Scotch next time.
Update: reducing the mezcal to 10ml and slightly over-pouring the rest gave a better balance.
Fantastic drink, ambosia! I enjoyed this one very much using the mighty Sazerac Rye. (I skipped the syrup and reduced the Ango to a single dash, which suits my 'senior' palate.)
A little tip to help others follow Chris' link below as you can't copy and paste. In the URL at the top of this page, replace "19655" with the number of Chris' recipe "16410" and then hit return. A quick shortcut to get to another cocktail page you know the number of.
