Puffed skin shelf life

[KennethT]

I'm having a party and one of the bites being served incorporates puffed duck skin. The problem is that I don't want to puff the skin pieces at the last minute since I'd rather not have a pot of 400 degree oil around when there are tons of people drinking and milling about, possibly milling about in my kitchen. So, I'd like to puff them in advance (maybe that afternoon) and keep them...

The question is - how long will they stay brittle and crunchy? I have airtight containers, and a foodsaver canister, and many many packets of dessicant if that helps...

Should be doable - chicharrones are puffed up to a day in advance with no loss of texture, and they're not normally stored airtight by any means. If you can keep your duck chicharrones airtight with dessicants, they'll probably be perfect when it comes time to serve them.
