How long does opened doubanjiang last? It's best to finish it quickly.
As home cooks, we know a lot about doubanjiang, the spicy fermented broad bean paste that everyone loves. It's the secret sauce that gives a lot of delicious meals their special flavor. But here's a common situation: you've opened a jar of doubanjiang, and before long, you see it start to change or even go bad. So, how long can doubanjiang stay good after it's been opened?
Unopened doubanjiang is tough; it can last for a full 18 months. That's a pretty long shelf life, but I recommend that you use it up within a year. But once you open that jar, time starts to move a little faster. You have about a month or two before it starts to go bad at room temperature.
Putting your opened doubanjiang in the fridge will give you a little more time. Think of it as a neat little time capsule that keeps your paste fresh for longer. But here's my fail-safe tip: try to eat it all up as soon as you can after you open it. This way, you don't have to worry about storing it and you don't have to worry about it going bad.
In short, opened doubanjiang doesn't last as long—about one to two months at room temperature, and a little longer if you keep it cold. But to really taste its flavors, I suggest you eat it pretty soon after you open it. After all, why let a tasty ingredient sit in storage? Fresh is the best way to taste the key flavor. So go ahead and make those dishes the way you like them, and enjoy every last drop of your doubanjiang!
