In Cape Verde, this kind of corn is easy to find: dry yellow or white corn kernels. Years ago people had to pound it themselves to remove the shell; nowadays you can buy it at the store without any pounding necessary. It's definitely not the same as sweet corn.
This corn is used to make cachupa, a stew that's often considered the "national dish".
How can I find this in the northeast U.S.? What's it called? Or, if it's truly difficult to find here, what would be a good substitute?
When it's imported into Cape Verde, it usually comes from Brazil. Yoki is the brand I've seen most often, but their site doesn't list it. Sinhá does list it, as for "canjica" (according to Wikipedia, that's canjica a.k.a. mugunzá, not canjica a.k.a. curau.)
Wikipedia's article for cachupa says it's made with hominy, but I think someone was confused... hominy seems to be strictly from Central and North America, from what I've researched. There's "hominy" at my local store, but it's in a can, reinforcing my idea that this is not the same thing.
