Transfer to a clean jar. In our experience, the sauce stores well at the coldest part of the refrigerator (e.g., in the way back) for a good 2-3 months. And, of course, always dip into it with a clean spoon/chopsticks to preserve it. If there’s any foul smell or the sound of gas escaping when you crack it open, discard it. But we’re betting it doesn’t last past the 2-week mark!
