Every district in Chiang Mai has an open-air market, a place to barter for food, veggies, fruit, flowers, and a whole bunch of other stuff. I work in the Nong Hoy district, so 2 or 3 times a week I go to the Nong Hoy market during lunch. It's a sprawling-covered-roof-without-walls-sort-of-building with all sorts of small stalls underneath selling a bit of everything.
One of the things I buy a lot of at the market is fresh fruit. Oh boy, we love fresh, tropical fruit. Ann blends a couple different kinds of fruit together with fruit juice and ice and wow! we got a fruit smoothie like you wouldn't believe. I had banana/pineapple/dragonfruit yesterday. I typically buy most of my fruit from the same lady every time. I'd like to tell you that it's my keen eye that selected this seller among the others, but the truth is that I buy from her because some of my Thai friends, who first took me to the market, bought from her. I just copy them. :-) This lady does have the widest selection, though I usually get my bananas from a different lady.
So, do you think you know your fruits? Take a look at this picture, which shows all the fruit she sells. How many of them can you name? Leave your guesses in the comments, and I'll moderate the answers.
