The absolute worst food that I have ever tasted was a berry fruit leather which looks like the fruit roll-ups that are in stores now. We were visiting Vermont when I was a child and went into an antique store and they had Vermont's famous, traditional maple sugar candy and I wanted that, but I was given this red, flat, rolled up leather. It was awful. It was tough, gritty and had an off, sour taste and I must admit that I spit it out and refused to eat more. It was so bad that the memory of it has stayed with me throughout my life.
