No but it's tricky (or at least the time I tried wasn't successful) and my husband is married to his Hellmann's and he's by far the biggest mayo eater. I'm not opposed to it and I've tried the avocado oil based ones, but they're VERY expensive and the taste is, well, acquired I guess. So unless there's a foolproof method I don't know about, I haven't ventured back into making my own.
