Tripe rations have the second-highest probability of all comestibles after food rations: 14% of randomly generated comestibles will be tripe rations.
Orcish Rangers start with a stack of 4-8 tripe rations in place of the role's standard cram rations; all orcish starting characters in non-Wizard roles may also start the game with 1-2 tripe rations as one of their random food items. Any cram rations or lembas wafers will be replaced with tripe in both cases.
When eaten, tripe rations provide 200 nutrition, but non-rotten tripe also has a 1⁄2 chance of giving you nausea along with a single experience point. If you are a Caveman, an orc or a non-humanoid carnivorous monster (e.g., you became a canine through lycanthropy), you can eat it without becoming sick.
Tripe rations are a treat for carnivorous pets such as dogs and cats, and increases the pet's apport when fed to them. Throwing tripe to a hostile or peaceful cat or dog will tame it, as will other forms of meat save for corpses; carrying a tripe ration in your main inventory will make a carnivorous pet stick around closer to you.
Tripe rations are primarily useful in the early game for taming hostile domestic animals that can otherwise do serious damage, allowing you to preserve more dependable sources of nutrition. They can also be instrumental in stealing from early shops, especially when money is scarce - entering a shop that has tripe before your pet does can be useful, since even if you don't have the money to buy the tripe, it still counts for apport if you pick it up and drop it.
Allowing your pet to eat tripe that you've recently handled raises apport, making the pet more likely to pick up items - keeping tripe in your inventory also entices carnivorous pets to keep close by, making pet management slightly easier. As tame cats and dogs will attempt to devour a tripe ration on sight, try to grab any tripe you see lying around before your pet can get to it, if only so you can raise that pet's apport.
Non-orcish characters can use tripe a source of confusion for reading scrolls, similar to eggs. The experience point gained from eating a tripe ration can also be used to regain a recently drained experience level, especially for pacifist conduct.
Tripe rations have been present in the game since hack121, a port of Jay Fenlason's Hack.
When starting races were introduced in NetHack 3.3.0, orcish player characters except for Wizards could start the game with tripe among their random extra food items. There was intended to be code for an orcish character's initial inventory that additionally gave them tripe rations in place of cram rations and lembas wafers, which is properly implemented in NetHack 3.6.2.
Tripe is a type of edible food made from the lining of the stomachs of various farm animals such as cattle, pigs and sheep, with the mucosal lining removed. Beef tripe is typically the most common type, made from a cow's stomach; other suitable animals include deer, antelope, goat, ox, and giraffes.
"Dressed tripe" or "washed tripe" is prepared by cleaning the stomachs and trimming the fat off before boiling and bleaching, which turns it a white color; this color is more commonly associated with the tripe seen in market stalls and butchers' shops. Dressed tripe was a popular, nutritious and cheap dish for the British working classes from Victorian times until the latter half of the 20th century, but has since come to be regarded as a pet food - this is the basis for its portrayal in NetHack. Dressed tripe remains a popular dish elsewhere in many parts of continental Europe, such as Portugal, Spain, France, and Italy.
- Yak - dog food!
- You ate a non-rotten tripe ration and are not an orc, gaining 1 experience point and having a 1⁄2 chance to become nauseous for 1d14 (more) turns, unless you are a Caveman.
- That tripe ration was surprisingly good!
- You ate tripe as a carnivorous non-humanoid.
- Mmm, tripe... not bad!
- As above, while an orc.
- Tastes great! Less filling!
- As above while also hallucinating.
If you start from scratch, cooking tripe is a long-drawn-out affair. Fresh whole tripe calls for a minimum of 12 hours of cooking, some time-honored recipes demanding as much as 24. To prepare fresh tripe, trim if necessary. Wash it thoroughly, soaking overnight, and blanch, for 1/2 hour in salted water. Wash well again, drain and cut for cooking. When cooked, the texture of tripe should be like that of soft gristle. More often, alas, because the heat has not been kept low enough, it has the consistency of wet shoe leather.
