Crafting recipes come from Bukkit.recipeIterator(), which is authoritative
for this exact version. Player questions are Portuguese and Material names
are English, so the subject of the question is searched on the pt wiki and
prop=langlinks&lllang=en gives the English title, which uppercases onto the
enum constant.
Matching material names against the question directly does not work.
Measured over twenty realistic pt-BR questions it resolved 1 of 20, and that
one ("tridente" containing "trident") by coincidence rather than
translation. Through langlinks the same twenty resolve 17 of 20.
Brewing is not exposed by Bukkit at all: there is no brewing Recipe type,
PotionBrewer has no getter or iterator, and vanilla brewing is hardcoded in
PotionBrewing rather than registered as a recipe. Potions therefore come
from a hand-written pt-BR table. This is what actually answers the
fire-resistance question that motivated the feature; recipeIterator() alone
never could have.
Ingredients are read through getChoiceMap/getChoiceList. The deprecated
getIngredientMap/getIngredientList collapse a choice to one arbitrary stack,
printing "oak planks" where the recipe accepts any plank.
The design doc claimed recipeIterator() closed the potion case. It did not;
corrected to record what is true.
