Replicator ration
From Memory Alpha, the free Star Trek reference.
An energy crisis on the starship USS Voyager facilitied use of the replicator systems to be limited. The crew were issued with replicator rations to allow them at least some home comforts. They would typically use them for items which could not be made/grown/approximated onboard or procured elsewhere.
Replicator rations were sometimes used as currency. Lieutenant Tom Paris set up a gambling pool among the crew attending Chez Sandrine's.
Rations were often used for that addictive beverage: coffee. Towards the beginning of the rationing, Neelix encourages Captain Kathryn Janeway to set a good example for the crew by not using her rations for coffee. Paris also at one point considered using his remaining replicator rations to enjoy a raktajino. (VOY: "The Cloud", "Meld")
