I used corn-flavored water as a basis for a corn chowder that I made. I boiled some frozen corn on the cob (kinda old), cut the kernels off, put the cobs and kernels back into the water, simmered it some more, then strained it. I threw away the corn and cobs, reduced the remaining liquid, and used it as the main liquid in the chowder. I rendered bacon, sauteed onion and roasted pablano chilies in the bacon fat, added some flour, then added the corn liquid and fresh/frozen corn kernels. I finished it with cream.
