I'll have to take your word for that. I don't even care much for mac and cheese made from scratch. Too soft. Too gooey. Too heavy.
I never don't feel like making it myself. The lowest I'll stoop is making ranch from yogurt, mayo, and Hidden Valley mix. Other than that, there's no commercial salad dressing in my house.
I prefer making ranch from scratch, but that's actual work. Also, it depends on having buttermilk in the house; buttermilk is not a stock item, since I'm from the North. I buy some when I feel like making ranch or creamy garlic.
The only dressing to which I add sugar (just a pinch) is sherry vinaigrette. For some reason, sherry vinegar is more powerful than other vinegars.
I have a rotation of half a dozen or so vinegars (plus lemons and limes) and a couple of oils that combine to form a pleasing variety of salad dressings. I have a salad for dinner (usually with some lean protein on top) nearly every night.
My husband allows only Heinz in the house. Since I don't use ketchup (except as a base for barbecue sauce), I buy what he likes.
