This question already has an answer here:
Some food contains capsaicin which is a substance that comes from chili or pepper and gives food its burning taste. In english you call this type of taste "hot". In German (my native language) we say "scharf" which literally is "sharp" in english (sharp like a knife).
I am suffering form a capsaicin intolerance. To me even low amounts of chili or pepper make my mouth feel like burning in hellfire. Sweat flows out of every pore of my skin even when I taste food that contains very small amounts of this substance that others won't notice.
So in a restaurant I want to order food that contains no capsaicin. In German I can say "Bitte nicht scharf!" But in english this is "Please not hot!"
Last year I spent 2 month in London and very often I got food that was cold and tasted like burning fire (they gave me the normal spiced food but didn't heat it). To make clear what I want I can say in German "Bitte nicht scharf, aber heiß!". How do you say that in english? "Please not hot, but hot!"?
This question is different form How to say that food is hot (temperature) without the listener thinking that I mean "spicy"? because the answers to the other Question doesn't help me to order food that contains no capsaicin.
The other question hat its focus on the aspect of temperature in the word "hot". This is not my focus. My focus is the amount of capsaicin in the food that is expressed by talking about "hot food", and how to avoid getting served such food.
Obviously I didn't make it clear enough: I love spicy food. I love mustard, horseradish, onions, garlic, wasabi, ginger and so on. I hate food that tastes boring and bland. And I hate cold food that usually is served warm. I just want no capsaicin in my food. Capsaicin is in Chili, Cayenne pepper, Piri piri, Tabasco pepper, Jalapeño and many other fruits from plants of the genus "Capsicum". Also Hungarian paprica (used for Goulash) and Peperoncini (you often find them on pizzas) contain capsaicin, not really much, but too much for me.
There is no capsaicin in horseradish, wasabi, onions, garlic, and most other spices. I have no problem with those spices. I like to eat food that is spiced with them.
