My sister stopped by this morning as I was preparing a skillet near filled with water to poach some eggs. See was surprised to see me add 2 tablespoons of vinegar to the water. She didn't know the vinegar makes the egg whites stay together. Vinegar can be an effective cleaner too. I use it to clean my coffee maker. One of my summer time treats is raw cucumber slices, onions, and sea scallops marinated for 24 hours in red wine vinegar, minced garlic, lemon juice, lime juice, and tobassco sauce. How do you use vinegar?
