It becomes much easier when you realize the answers are alphabetical - maybe mix them around to make it more challenging? Also, is it cocoa or cacao? Cocao is a strange mix of the two.
Salchicha is "sausage" or "hotdog/weiner", not "bratwurst"- too specific. Also, galleta is more commonly refering to a cookie or cracker. Aguardiente should accept "fire-water", at least, since it is rarely thought of as a brandy, and powdered milk is the more common name for "leche en polvo". Thank you, fun quiz!
The tree it comes from is the cacao and it is the way it is written in most languages ( sometimes with k's instead of c's, )
