Notes I make a double batch, and it about fits a quart Mason jar. This way I can keep it sealed. This has a flavor similar to a Pennsylvania Dutch sweet and sour salad dressing, and we're going to try it on salads next. But the real memory is all those years, when Grandma would make us a bag full of turkey sandwiches, for our trip back home, slathered with this delicious sauce. Enjoy!
