Richard Stallman’s rider 4

Or, You need to know what I dislike

avocado, eggplant, usually
(there are occasional exceptions)
hot pepper, olives, liver
(even in trace quantities)

stomach and intestine, other organ meats
cooked tuna, oysters, egg yolk
if the taste is noticeable,
except when boiled completely hard

many strong cheeses, especially those
with green fungus, desserts
that contain fruit or liqueur flavors
sour fruits, such as grapefruit

and many oranges, beer, coffee
though weak coffee flavor can be good
in desserts, the taste of alcohol
so I don’t drink anything stronger than wine
