What fruit, often soaked in a suspension of food coloring, is found on top of a Manchester tart?
Maraschino cherry:  In their modern form, the cherries are first preserved in a brine solution usually containing sulfur dioxide and calcium chloride to bleach the fruit, then soaked in a suspension of food coloring (common red food dye, FD&C Red 40), sugar syrup, and other components.
