To keep mayonnaise fresher longer, remove the cardboard liner in the lid.
By Janette from Parkersburg, WV
Editor's Note: I have never heard this. Does Janette or anyone have any ideas why this would work?
I remember hearing this once, but cannot remember if there was a reason given. Perhaps the cardboard isn't "acid-free" or "antibacterial"?
My guess is that the cardboard/paper would attract the moisture in the jar and that would encourage mold to grow on it. Pam in RI
I agree. Cardboard is a porous material and with the moisture too, it could encourage the growth of micro-organisms or mould.
It works because the cardboard holds bacteria and moisture that speed up the mildewing of the mayonaise. I always remove the cardboard from inside the top.
