Rinse the cherries under running water to remove visible dirt.
Place the cherries in a large bowl. Add enough clean water to fully cover them. Add vinegar and baking soda.
Gently mix the water with your hands so everything is well combined. Let the cherries soak for 10 to 15 minutes. Do not exceed this time, soaking too long can make them soggy or dull the flavor.
Drain the cherries and rinse thoroughly under cool running water to remove all residue and vinegar smell. Shake off excess water, then let them air-dry at room temperature for up to 1 hour. If it’s too hot, gently pat them dry using a clean kitchen towel.
Line a bowl with paper towel and place the dry cherries inside. I don't cover the bowl, but if you do, cover loosely with a lid or towel (not airtight), and store in the fridge.
