Fred's Mushroom Sauce. My mother used it a lot and it was delicious, much better than the nasty-tasting canned mushroom gravies of today.
TastyKakes made with real butter and with a shelf-live of maybe a day rather than eons. So much better tasting! I'd gladly pay three times more + shipping to get them these days.
Will Twinkies soon be a "taste of the past" to future generations? (OK by me.)
