Carol, I used to have a recipe for broiled salmon, with a Dill Sauce topping consisting of mayo mixed with whipped egg whites and lots of dill...
You put the topping on the salmon at the end and then put it back under the broiler for a few minutes, til browned...
It was fantastic, even people who hate salmon raved about it!
It was like a Merangue/Dill topping for the fish...
I wish I could find that recipe again!
alas, it was on a a piece of paper that I have long since lost! (my, "rhymes with itch", of an ex probably took it!)
Long before the days of PC's and paperless...
