When I eat spicy food, I only taste burning.?!
So wtf?
Answers:
Start off with milder spicy food and work your way up. You have to crawl before you can walk
Well if you mean Tobasco sauce, then I'm with you. Tobasco sauce just tastes like smoke and totally artificial.
Try chopping a jalapeno pepper and mixing it in a large pot of soup. You will taste spice and not just burn. Or order Tom Yum soup at a Thai restaurant or eat kimchi in a Korean restaurant.
ease of the hot stuff and start bit by bit until you reach your comfort spice level until then keep a fire exstnguisher handy by the sound of it
Eat milder food and gradually build up a tolerance.
