Oftentimes members (or investigators) try to honor missionaries by feeding them special foods -- many of them delicacies in the local cuisine. For example, we like to feed the missionaries grilled Pacific Northwest salmon.
I would guess that most missionaries have at least one story of special or surprising foods. I know I had my fair share of exotic dishes that I didn't recognize (and perhaps it was better that I didn't). My favorite story, however, is of the green sister missionary in France who was served duck embryo soup. Luckily her companion was able to help her with the duck embryo part and she lived to tell the tale.
Kinda makes whole chicken soup pale in comparison!
