my question is, is this okay to do - will it preserve it well? the longest i've kept the can like that was for a week.
what are some better methods to preserving opened red bean cans?
i buy the japanese brand, so even if they have directions to preserving it, i can't understand it.

here's an idea of the can that i am talking about. it's not 'paste',
because in it there are beans in its original form
help is much appreciated
