From what I remember you're right, the rest of the ingredients go in the shaker before step 4. I think there's been an automated standardisation to most of the recipes and some of them have got a bit muddled.
Very easy to make and tastes excellent. Nice to have a 3-ingredient Belle de Brillet cocktail too. Made it with homebrew dry cider and one bottle making four of these was very handy!
This is the best cocktail I've found for Black Tears so far. Brings out the chocolate and coffee notes, and has a great balance between fruit and spice. Do think it needs a good vermouth - Strucchi rosso works perfectly.
