Oh man, I tried brining chicken once and it was a total disaster. Ended up with meat so salty it could have seasoned a whole pot of soup. The texture got weirdly spongy too, like a kitchen experiment gone wrong. Haven't had the courage to try it again since.
Yeah that spongy texture happens if you brine too long. I do a quick 30 minute brine and it just makes the chicken juicy without going overboard on salt. What ratio were you using?
