Homesteading Family on YouTube had a video about fermented mayonnaise. They say it keeps longer in the fridge. I haven’t tried it myself, but you may want to check it out.

Great, thanks, I’ll check it out.

I think the way it’s made “shelf stable” in the grocery store is to vacuum seal it (in addition to all the chemical stabilizers – chemical crap show). Maybe you can get more out of it if you try vacuum sealing it in a glass jar? Full disclosure: I haven’t made mayo yet, so I’d love to know if you try this and it works.

Even with all the preservatives they put in store bought mayo, it still isn’t very shelf stable. Since they started using PLASTIC JARS, it doesn’t last 6 months on the shelf before it goes rancid & turns colors (yellowish color). I had bought a few jars to have on hand to make potato salad & other salads that require mayo for our family get-togethers/cookouts. I usually have to make a lot of sides in large quantities. I got one of the remaining jars out at Thanksgiving and it had turned yellowish in color. I opened it and it was rancid. Best Buy Date was May 2023. It had been kept in my big pantry that is cool & dark so go figure.
I like your idea of vacuum sealing the remaining portions in smaller canning jars. I would also add some lemon juice as suggested above. Remove the air by vacuum sealing could also help stabilize it even more. I may try that when I make homemade that I use, otherwise, for myself.
I vacuum seal A LOT of things to help keep them fresh longer. Even dry goods, beans, pasta, etc.

Yes I made this mistake in 2021. I bought a CASE of small squeeze bottles of mayo. Thinking of throwing it all out.

[Summerhat-n-Chicks]

Good idea, but I’m not sure if vacuum sealing it works. Wouldn’t it try to suck out the Mayo ? I have a hand pump to vacuum seal jars, guess it would be worth a try .

I am currently using ajar of mayo that expired last May. Still tastes fine. Hellman’s seems to go bad quickly. I think the shelf life of the foil individual packets would be shelf stable longer. Checking into this now. The price is pretty much the same

[Summerhat-n-Chicks]

I think so, too, that smaller jar sizes last longer. The individual foil packet have the additional advantage of the Mayo being kept in the dark until opened. These may be all factors in the preservation time.

It’s a very simple method, as explained in HF also. U add a tbsp of whey and then let the mayo ferment 8 hrs on counter. It doesn’t taste any different.

More lemon or vinegar would not do the job. Neither does more salt.

We just don’t eat mayo except for creamy salad dressings…deviled eggs, potato n mac salads are maybe 4x a yr happenings; sliced or deli meat sandwiches never happen; tunafish, egg salad or chicken salad is rare. We’s just broke lol Dressing isn’t needed alot last 6 months as salad fixings are out of budget.

My daughter went thru a spate of deli meat buying so then she used mayo.

So rly look at do u need mayo even? If ur eating pbjs mostly or beans n rice at lunch n it’s not picnic time either, prob just buying a small jar will more than suffice. If u can find a brand that doesn’t spoil unopened <<messing with our food>>

[Summerhat-n-Chicks]

Thanks for the tip, I’m going to try this.

We don’t eat a lot of mayo either, but we like to eat it on the occasional burger and whatever, so a little goes a long way.

I made mayo a week ago and put the leftover in the fridge. I just pulled it out and it is still fine. And I’m wondering if it lasts longer because I made it with bacon grease instead of oil. Something to consider. I still have some left, I’ll update later with how long it stays good.

[Summerhat-n-Chicks]

Bacon grease ? from lard ? How much does it solidify ?

[DoubleS]

Not from lard- I save the grease after cooking bacon. Pour it in a jar and store in the fridge. Can be kept on the counter if you have a cool kitchen.

It does firm up in the fridge, but as soon as I get it out it softens quickly while I’m mixing it. It adds a smoky flavor to the mayo, so I don’t use it every time. I made this last batch for some turkey bacon and avocado wraps, so bacon grease mayo was a good fit.

[Summerhat-n-Chicks]

Sounds interesting for sure. Another good use for left over grease.

[Summerhat-n-Chicks]

I thought about lemon juice, I might split several portions and try various things.

[Summerhat-n-Chicks]

I was a little thrown off by the extensive recipe as well, but I might try it in a simpler version just to see.
