I am one of those people. An entire burrito can be ruined for me with just a few pieces throughout. I always feel so bad when someone gives me food with cilantro.
That sucks. I just made some enchiladas with diced cilantro stem last night (more flavor in the stem). Don't feel bad, I'm sure they don't mind when they realise it tastes bad to you. Now I'm just sad you don't get to enjoy the true taste of cilantro.
Yeah, it's used in a lot of different cultures' foods. Like it you eat Indian or Vietnamese food, theres a decent chance it could be there, not just Mexican, which is what I think a lot of people think of when cilantro is used in cooking.
