ehBeth, nice story -- and good to keep in mind.
I stand corrected on the mayo ingredients. It was a long time ago that I looked... As far as quantity, I use maybe one of the smallest-size jars in a year (unless I'm making food for a crowd) so I think health-wise, I'm OK
And, depending on the pickiness of the crowd, I'd probly buy mayo for that because most people prefer it.
