Several New York sightings of ice cream sandwiches — and several days of hot humid weather — reminded me of a vendor I once came across in Lumphini Park, in Bangkok. He offered a choice of flavors for his khanom pang ai tiim, which in its more elaborate renditions is sometimes translated as "sundae in a bun." All I know of this flavor is that it was flecked with green and popular with the Thai-speaking customers ahead of me. The seven small scoops sat high on the bread because they rested on a seam of sticky rice. Grand total: 10 baht, or about 28 cents at the time.
