I buy this type of corn on the cob steamed from a Lee's Sandwiches near my house. It's also sold at the Chinese and Korean grocery stores, presteamed and frozen.
My mom, who grew up in Vietnam, said that she hasn't seen this variety that often since her childhood. It has a wonderfully chewy, sticky texture when you bite into each kernel. Also, they aren't as sweet as regular corn.
I've seen them both yellow, or yellow with some brown kernels. They are always plump and shiny.
Have you ever had sticky corn? What are your thoughts on it?
