Common questions
Can you freeze mayonnaise?
Not with good results. Emulsions and cultured creams separate when frozen.
What happens if I freeze mayonnaise anyway?
It is not a safety problem, but the texture falls apart when thawed: it separates, curdles or turns rubbery. Anything frozen by mistake is safe to cook with if it was fresh when it went in, but it will not be pleasant to eat as it was.
Why does mayonnaise split in the freezer?
Mayonnaise is an emulsion of oil in water held together by egg yolk. Ice crystals break that structure, and on thawing the oil separates out as a curdled, oily mess. No amount of whisking will reliably bring it back, so buy jars you will finish rather than freezing leftovers.
