I would like to complement the answer. "なじんで"　is the conjugative form of "なじむ". You can say it with Kanji character like "馴染む". Then, "なじる" means " to twit " or " to blame". You can say it with Kanji "詰る". Yes, I think it is confusing because the sounds resemble each other.

dictionary form is 馴染む なじむ 油がフライパンになじむ is oil soak into hot pan.
