So about 2 weeks ago I opened up a can of coconut milk but didn't use the whole can. I poured the remainder of the coconut milk in a glass jar, sealed it tightly and put it in my refrigerator. Online sources state it will last about 7-10 days, but I am hoping it lasts longer. It still looks and smells fine. What's the longest any of you have kept canned coconut milk after opening? How do I know if it's gone bad? Thanks in advance.
