The clever big snack companies (Lays, Pringles, etc.) have done a spectacular job catering to local tastes. The above pictures shows two pretty normal looking bags of potato chips--until you take a closer look at the small picture and read the Thai. For people who live hundreds of miles inland from the sea, it's remarkable that all seafood ranks high on their list of "most desirable flavors." It's even more remarkable (to me) that many of the creatures we think of as saltwater, ocean-going creatures are also found in fresh water ponds hundreds of miles inland such as shrimp, crab, clams and mussels.
Last night I dropped by the local bakery which has the normal looking stuff--cookies, brownies, cakes-- along with a number of Thai oddities. I bought what looked like a normal sweet bun filled with something (I expected Bavarian cream of course). When I got home and cut it open (I've long learned not to bite first) out poured warm, translucent mayonnaise and shredded pork, which has the consistency of very coarse cotton candy.
Mayonnaise and pork from a bakery? Yup. A cold cooked hot dog wiener buried in what looks like a Danish pastry is pretty popular too. So be careful when you buy that Danish to go with your morning coffee. You may end up looking for the ketchup for dipping your Danish hot dog.
