Vietnamese food for beginners: Mon cuon (Rice rolls)
Saturday, April 03, 2010 (GMT+7)
Rice rolls are produced everywhere in Vietnam, with the most well-known being goi cuon, but those that are made in Hanoi have their special characteristics.
The wrappings of banh cuon are as thin as a sheet of paper, appearing as edible alabaster, soft yet offering something to the teeth. Ingredients may include grilled pork, fried bean curd, or vegetables. If you’re really lucky, they’ll add a drop of coleopterous essence (a highly aromatic secretion from the gland of a type of beetle).
