What's the greatest extent (as in the most amount of time) to which you've eaten something past its expiration date with the food still being enjoyable?
I just used up a bag of dried dates that were a couple years past the date on the bag. They weren't noticeably different from when new. (They went into something baked so also seemed less of a big deal.)
I'm thinking about this and not sure but have made fruit syrups for cocktails, recipes said they last a week in the fridge, but still tasted great after a year. I always just use those until they are gone, but all I had were lost in the hurricane as we had no refrigeration for a week.
In 2011 I was in an unfamiliar kitchen and had some porridge in the morning. I put some ground cinnamon on it that was in the cupboard and noticed that it was particularly good cinnamon, much more flavoursome than I was used to. I looked at the bottle again and it was the same brand I always use myself at home so I didn't see why it should be so much better but I noticed that the although pretty similar the labelling seemed subtly different than I was used to. I looked at the expiry, it expired in 1986 and the label was different because they'd updated the design since. I don't know why the 25 hear old cinnamon seemed to taste so extra good, I would have thought that if it wasn't somehow rotten and sloiled it'd at least have lost basically all its potency but somehow it was super nice. I even had extra after this discovery.
Yeh it was Masterfoods ground cinnamon if I recall. It really defies intuition because things like nice aromatic spices should get progressively weaker flavoured over time. I feel compelled to say this may have been a freak occurrence and it's probably unwise to seek out 25 year old spice.
Assuming it's cultured buttermilk, you can keep it going by adding milk when it's almost gone, then leaving it on the counter overnight. It's like yogurt but more robust, less fussy.
I've eaten pasta from a sealed, unopened bag that was 4 years past the date. The only difference I noticed was a few pieces breaking apart after cooking and it maybe cooked a tad faster.
Unless stored in some unusual way, the nut oils would almost certainly have been rancid. Not very healthy for you, but wouldn't give you food poisoning. Salt can hide the taste of rancid oils.
Actual food? Probably yogurt at like one or two months. It had been sealed up until then.
I've had table syrup that was at least 4 years past the expiration (it actually still had the aunt Jemima on the bottle is how old it was).
A few days ago I finished some baking powder and my partner brought a big bottle home and I was like "oh it's okay that stuff doesn't expire!" Then I looked at the previous container I had and found out it had, in fact, expired in 2017. Don't think it affected my baking though.
I mostly just eat stuff without looking at the dates unless it smells bad or is moldy.
There's some mayonnaise in the fridge a couple years old I'll use on sandwiches. After family holiday get togethers there's always leftover ham or turkey, that's about the only time I'll use mayonnaise. Every year I'll pull it out, look at the expiration date and make a choice. Go get a new jar that will only get a third used or live life on the edge and slather on the old stuff. I call it refrigerator roulette
Some brands of mayo actually say on the jar that you don't need to refrigerate them. In the fridge, I'd probably keep that 2 or 3 times longer then the jar claims it should last.
I think a lot of people are confusing the “best by” or “sell by” etc. dates on foods (in the USA anyway) with an “expiration” date. The only foods in the US that actually have expiration dates are infant formula. NO foods expire exactly on some arbitrary date stamped on the packaging. The dates are listed to give consumers an idea of when they should think about consuming the product, many with a large amount of useable time after the date printed.
Don’t believe me? Here is the USDA’s FSIS explanation of their own regulations.
I don't press my luck with expired foods. It's on me if I don't eat something and I've had so long of a time to eat that food by. Like canned foods that go all the way out an entire year or even two. I just don't want to ever experience botulism or food poisoning of any kind.
I rarely press my luck either, though mostly because the fact I know how to use what I buy and buy what I use makes it so I'm not used to finding something that's past an expiration date. It used to be (and this is still slightly the case) I had to be "urged" to be afraid of it by people who were amazed I'd happily take anything regardless of a date.
