We used to pack brown sugar right on top of the espresso before pulling a double shot and running it into about an oz of half and half. Delicious and easy to drink immediately.
Afaik this is how to make a Cuban espresso. I was taught to mix the sugar with the first few drops inside the moka pot, but I'm sure it would do the same thing mixed in a glass
Assuming that's an Italian style dark roast that would need sugar anyway, I'll allow it. It's certainly nice to look at. If that's a nice light roast single origin then you're a monster and should go straight to jail.
