My concern about the fat in mayo is because I've lost 30 kg over the last 2 years and still have about 15 more to go to be in my healthy weight range . . . I love mayonnaise and thought it would be just too tempting. I would like to eat it with a spoon if I had my druthers! Anyway, the rest of the family have voted for homemade mayo, so I guess I will just have to try and exercise moderation!
