What word other than hot can I use to make the distinction between hot as in temperature and hot as in very spicy food?
Especially in connection with food, the word hot is very ambiguous (well, unless it's chili-spiced ice cream, I suppose).
Many other languages have a distinction and use separate words. What about English?
Clarification: I know that I can use the word spicy, I'm more interested in avoiding the ambiguity when using the word hot (meaning temperature). Perhaps that was unclear.
