SRS, when I said we would pick out the raw red onion we thought it would be just a few pieces of onion rings. We didn't think it would be half of the salad. If he was allergic he wouldn't be able to eat the salad if the raw onion had touched it but picking them out is ok for him.

Mrrzy, oh yum! Cilantro aka coriander. My favourite Thai dish is green chicken curry. It wouldn't be the same without the cilantro.

Cilantro is definitely love-it-or-hate-it/can-or-can't-eat-it food but I'm not sure why. It might be a DNA thing.

I like watching the real-life hospital Emergency medical shows and people with peanut allergies can be in life threatening situations. One patient ordered fish cakes from a take away shop, had an allergic reaction, went into anaphylactic shock and found out at the hospital that she is also allergic to pine nuts which were in the fish cakes but not declared on the menu. I assume it is somehow related to peanut allergy. That would limit the use of pine nuts in yummy basil & parmesan pesto sauce.
