Ordinarily, I hate any combination of sweet and salt. If it's sweet, let it be sweet, but if it's salty, please give me more salt. I found myself eating my words (and a yummy dish, at that) today when I went to work at Sacred Chow. They'd made this cold fruit salad thing with onions and avocado and watermelon and mango and cilantro. And there was a dressing on there which had something sour, and salt and something something. It was quite good.
Lemon. That's what it was. Either way, I'm quite pleased. However, just don't tell anyone else, because I'm supposed to dislike my beautiful salt be adulterated with sweet.
