The ripe cherries are picked and immediately put on the drying patio in the sun to dry. The skin and pulp remain attached. The skin shrinks, locking the fruit sugars in. The cherry raisins up and drys hard around the seeds. The fruity flavors penetrate the porous seeds within. The mass, when hard and dry, is milled (like white rice) to remove the hardened pulp and skin.
The taste produced is sort of like blueberries or strawberries. A mix of sweet and sour fruit. The acidity is softer and mellower.
