Travelers passing through the small town of Saraburi, about 100 km north of Bangkok, may have noticed the almost absurd abundance of a particular snack. Resembling a small round pocket of dough similar to an Indian samosa or a Mexican empanada, the dish is sold in countless shops in the town and is known in Thai as kalee pap. If this doesn’t ring a bell, it may help if I reveal that kalee pap is the Thai pronunciation of the English words “curry puff”, and is a snack with obscure origins that has become wholly associated with this otherwise unremarkable town.
