In a small bowl, mix the gelatin with 4 ounces (1/2 cup) Montmorency tart cherry juice. Combine the remaining 8 ounces (1 cup) Montmorency tart cherry juice with the corn syrup, sugar, and salt in a 3-quart stainless steel pot. Stir with a fork over medium heat until it begins to simmer. Clip a digital thermometer to the pot, increase the heat to medium-high, and simmer without stirring until the ruby syrup registers 250° (about 15 minutes altogether).

When the syrup comes to temperature, transfer the thermometer to the bowl of a stand mixer and pour in the hot syrup all at once. Cool to 212° and add the gelatin. With the whisk attachment, mix on low speed for a minute to combine, then increase to medium-high and whip until tripled in volume, about 10 minutes. Scrape into a well-greased 8” by 2” square baking pan, cover with foil, and refrigerate 2 hours.

Once firm, pry the marshmallow from the pan and place on a powdered sugar dusted cutting board. Rub powdered sugar over the marshmallow, cut into six 1 1/2” strips, then cut each into six pieces. Tumble with the remaining powdered sugar in a large bowl and store in an airtight container up to a month at room temperature.
