I've use mayo with a little Sriracha hot sauce for dipping French fries, but I'm going to try your idea. I love using mayo in cakes, omelettes, and it's wonderful to 'butter' the bread for a gourmet grilled cheese sammy with tomatoes and avocado.

I used to own an antique shop and had to touch-up" antique furniture. I used mayo to remove white water marks from tables and dressers. Another use, I once owned a wire-haired fox terrier. If you have ever owned one, you know they are prone to skin problems. When "Duke" skin got hot spots, I rubbed a little mayo on his skin, let it dry, then gave him a bath. It worked when all else failed.

My mom would make my sis and me sit for her mayo special hair treatments. She mixed up other ingredients and then slopped that mayo mix on the top of our heads and combed it through our hair, then wrapped our heads in plastic bags to "soak". We had to sit in the bathtub as the stuff ran down our faces, and she stood by to rub the drippy mess into our skin under the notion that it would make it soft.

It took a lot of repeated soaping to get rid the heavy, oily feel of mayo, but I reluctantly admit that it worked, we had nice, shiny hair a smooth skin for a few weeks afterward.

then broil - holds in moisture and imparts nice flavor.
