I had sweet mayonnaise for the first time in Tokyo a few years ago and have since found it mixed into salads (mostly sweet corn or fruit salads) in Singapore and China. The first couple of times I tried it, I was really pertty icked out by the stuff. (Really, why ruin good fruit with this glop?) But recently, after working through a tube of it that I bought by accident, I found that it's grown on me a bit.
What's the story behind this strange condiment? Is it a Japanese creation? (The brand I see most often is Kewpie.) When did it come onto the market and when did it become popular? Where is it eaten in the world? And how do you like to eat it?
For anyone who's never tried it, it tastes a mix between "regular" mayonnaise (i.e. Hellman's) and sweet, whipped cream.
