In a pot, bring the water to a light simmer. Add the cinnamon stick, cloves, sugar, and orange vinegar. Add a small pinch of salt. Add the quince and let it simmer over low heat for about 15 to 20 minutes or until the quince pieces are tender to your liking. I prefer mine to retain a little bite. Let the compote cool down to room temperature before serving or enjoy while still hot.
