It's Tết again and I'm about to buy this traditional Vietnamese delicacy. However, since I'm currently trying out a Joylent-only diet, I'll only be able to eat it after a couple of days.
So my questions are:
How long can I safely store Bánh chưng in the fridge?
Can I preserve it somehow? I've heard that some people boil or freeze it.
Edit: I was able to find some information on Wikipedia, which says the following:
After unwrapping, bánh chưng can stay good for several days while a wrapped one can be kept for two weeks.
Unfortunately, the source is not available online, so I cannot verify its reliability and context. This also contradicts some posts on online forums, where people said it can last even several months! Given the composition and moistness of Bánh chưng, I seriously doubt it.
Edit 2: My second piece of bánh chưng is now safely waiting in the freezer. I'll edit the question again when I eat it with details about its composition and taste after unfreezing it.
Edit 3: It was pretty much as expected - a bit of a freezer burn, but otherwise it was very close to its original form.
