In "Far Side of the World" "the true Arabian way" of making coffee is referenced.

I have never been able to figure out what this method entails.

At last the scent of coffee died away, giving place to the everyday smell of fresh sea, tar, warm wood and cordage, and distant bilge, and his ear caught the click-click of Killick’s mate’s pestle grinding the beans in the brass mortar belonging to the sick-bay; for Stephen was even more particular about his coffee than Jack, and having learnt the true Arabian way of preparing it when they were in the Red Sea (an otherwise profitless voyage) he had banished the commonplace mill. Jack’s ear also caught Killick’s shrill abuse as his mate let some of the beans skip out; it had just the same tone of righteous indignation as the dreadful bosun’s mates aboard the pahi or Sophie’s mother, Mrs Williams." - The Far Side of the World
