‘This coffee has been heated up. Boiled,’ he said, looking at his purplish brew. Killick’s face assumed a mean, pinched expression, and the thought ‘If people lay in their cots till all hours while others is toiling and moiling, they gets what they deserve’ very nearly found expression; but in fact the coffee had been boiled, a crime not far short of hanging at this time of the Captain’s day, and Killick contented himself with a disobliging sniff and the words, ‘There’s another pot coming up.’ - Desolation Island
Philip’s steward might be as discreet as a cat, but Jack would have given all his discretion and pretty ways for a pot of Killick’s coffee. He had not had a decent cup since the Java. The Americans had been kind, polite, hospitable, and their sailors thorough seamen, but they had the strangest notion of coffee: a thin, thin brew – a man might drink himself into a dropsy before the stuff raised his spirits even half a degree. Strange people." - The Fortune of War
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
