As Peter Konkoly, this cocktail's creator, says, it is reminiscent of a Last Word. However, we prefer this tasty drink served on-the-rocks as an aperitif...
We do a variant of this whereby we substitute 25ml Nonino Grappa and 5ml Luxardo Cherry Sangue Morlacco for the eau-de-vie. That way, we can keep the Suze at 30ml, as specified. Nice and bold and luscious for us.
Coming back to this, we've now decided that, in place of the eau-de-vie, the split that offers the best balance is 20ml Grappa and 10ml Cherry Liqueur. A sweet spot for us.
