Item: Day old fresh croissants
Prep: individually sealed in ziplock backs with as much excess air sucked out as we could get without squishing them.
Results: Excellent! defrosted pretty much like fresh. Possibly slightly stale/crispy on some parts, but once warmed in the microwaved as I did, or if you toasted it, the texture and taste was perfect. I am only going on how it felt, so it might not have had any bad spots at all. The Costco croissants on sale was an excellent by, but even at full price ($9.50) I will certainly buy them again to have on hand for breakfasts and lunches.
