I don't make mayonnaise, although I have in the past. Simply don't use enough to make it worth my while. I buy a good whole-egg mayonnaise at the supermarket and do with that.
I remember my mother's condensed-milk mayonnaise, made according to the recipe on the label of the tin. As soon as the weather got warm in springtime, she'd start making it, and it was a regular pantry item all through the hot weather until the end of summer. All the other mums made the same mayonnaise, so that's what all the kids I grew up with thought mayonnaise was.
Except the family with the French grandma, who made real mayonnaise at Christmas time. I used to spend Christmas-day evenings with them, being friendly with their daughters, and I have to admit that I thought their mayonnaise was strange and not nearly as nice as Ma's condensed-milk version. What you're used to sets the standard, I guess.
A few years back, I tracked down the recipe from the label, and made a batch of condensed-milk mayonnaise, to see if I still thought it tasted good. I didn't. It tasted awfully sweet and sickly to my adult taste-buds.
