If I had seen this family recipe written out before trying this, I never could have imagined how tasty it is. I encourage you to make this before deciding you won't like it. It's simple enough, so why not?
Someday I'm going to try pureeing the ingredients to make it a smooth dressing. I wonder how that would turn out. I'll add a comment onto this post when I do.
Creamy onion dressing (makes 4 servings)
1/4 yellow onion, finely chopped
1/4 cup red wine vinegar
1/4 cup evaporated milk
2 tablespoons canola oil
generous sprinkling of salt
Whisk ingredients together and toss with salad.
