Kimchi.
I typically eat it with rice (steamed, white, slightly sticky… as nature intended). A bite of rice with a bite of kimchi at the same time. Adjust the ratio to suit your palate's tolerance.
Sometimes I add a few pieces to a bowl of soup. Spices it up a bit, but probably isn't an "authentic" way to eat it. Whatever; it's food, I eat it.
Nothing particularly scary in it - mostly cabbage type vegetable and spicy.
Same technique is used to moderate most curries. Curries may have increasingly daring ingredients.
My wife says I am insane to recommend these - jumping into the deep end, as it were. She thinks "italian sausage" is spicy and horizon broadening… and dishes like General Tso's Chicken are too.
