I'm trying to remember how Mom did it. I think she did the salt thing first. I don't mean a brine, I mean bleeding them for a few hours (probably overnight), then rinsed and squeezed them. Then your favorite Italian style salad dressing. I can't remember the brand she bought, but it was something that was only available out west at the time. Whatever you like will do the trick. Hmmmm. I'd forgotten about the pure onion salad. For those who don't know, bleeding onions, cucumbers, and other vegetables is just putting them in a bowl layered with lots of salt, then a plate or bowl, weighted (a large can of tomatoes or something that size will do). Then every few hours you squeeze and drain the liquid. After an over-nighter, you taste. If it tastes good, fine, you're ready to dress. If it is too salty, rinse and squeeze again before dressing. It's sort of like making kimchee!
