What are those red and green things in fruitcake?

Some are cherries, others are red-dyed pineapple, and all the green pieces are also dyed pine-apple, according to John Crawford, vice president of the famous Collin Street Bakery in Corsicana, Texas.Pecans are the largest single ingredient in Collin Street fruit-cakes, followed by batter, honey, raisins, pineapple, cherries, "and a minimal amount of sugar," Crawford said. "They'll keep well for 60 to 90 days refrigerated."
