Recipe as remembered.
Meant to be prepared in a 17 oz (485 ml) cup.
Add the cocoa into the cup, sugar on top. Pour hot water till approx 2/3 of the cup is filled. Stir rigidly until all the parts have dissolved. Add rum and port. Add milk on top, and stir gently. Let it sit for a moment and then take a nice sip 🙂
We used Ron Matusalem Gran Reserva (15 years) and Taylor's Tawny Port.
Name derives from “Zombie Chocolate Apocalypse”, because you won't feel the impact until you're done with drinking half of the second cup.
