In the interest of full disclosure, here's a recipe Aunt Vena sent this week. It has a little less mustard that I typically use and has just a touch of vinegar. Tried it today and I must say, I like it.....a lot.
Grandma's coleslaw was also different than Mama's. Grandma grated a little carrot and her dressing was some kind of sugar/vinegar combination.
Mama was not a fan of the sweet-and-sour kind of taste. Grandma was. Wonder if the difference is due to where ancestors came from: Coopers from Germany. Haydens/Dunns: not Germany :-)
