Hawaiians soak them in cold water to take out the pungency.
Shocked us east euros have never heard of it since our cooking skills peak at cutting raw onions and putting them on bread with burnt meat or tinned fish.
You're the first person other than me I've heard has this problem. I have it with garlic, too. Either is fine when fully cooked, though. I don't even have a sensitive stomach otherwise, I can eat chilis all day every day. Hbu?
That sounds rough! Glad it's better now. I'm perfectly fine with sour stuff too, except on a completely empty stomach. Not quite cooked garlic has made me throw up before though.
