I like coffee. I like Star Trek.
I’ve had a mild interest in the raktajino, a Klingon coffee drink commonly consumed in DS9. I’ve looked up a few fan theories and fan recipes. I haven’t seen any references to a canonical recipe, so I get that there’s a bit of fun and personal preference involved.
The only thing I don’t understand is why raktajino is commonly claimed to be made with liquor. On the one hand, I understand why Klingons might want a stiff additive to their caffeine. However, the context in which characters on DS9 drink it does not suggest the presence of intoxicants. I recall at least a few occasions in which bridge officers, while on duty, drink a raktajino. Surely even synthol is not OK when you’re on shift for Starfleet.
I’ve seen people suggest adding alcohol, but I think the idea is to simulate that Klingon coffee would have a sharpness or bite to it, rather than assuming that raktajino on the show would actually have alcohol. I played around with some recipes for fun and I actually mixed a few together and found something pretty delicious. I mix Turkish coffee, a small amount of whipped milk, cayenne pepper, cinnamon, and a little honey.
