How Maraschino Cherries Are Made

In case you were wondering.

The first step in this rather involved process is to preserve the cherries by soaking them in a brine mixture that consists of water, sulfer dioxide (as a preservative), and calcium chloride (to enhance firmness). This process will also result in drawing out most of the color and sugar from the cherries. The cherries will remain in this mixture for about five weeks.

In the next step, the yellowish-white cherries are soaked for about five days in a heated liquid sugar mixture to re-introduce just the right amount of sweetness. After that is achieved, artificial coloring is added, as well as artificial flavor.
