Place cranberries, orange juice, water, and orange zest in a medium saucepan. Bring to a boil over medium-high heat.

Off the heat, use an immersion blender, potato masher, or standard blender to process until mostly smooth, ensuring a fine puree for optimal texture.

Pass the hot mixture through a fine-mesh sieve set over a heatproof bowl, pressing firmly with a spatula or wooden spoon until only seeds and pulp remain. Discard solids.

Return strained puree to the saucepan. Add sugar and stir over medium-high heat until completely dissolved. Bring to a full boil, stirring frequently, and continue cooking until the mixture registers 101.5–103°C (215–217°F).

Pour the hot sauce into sterilized canning jars, leaving 6 mm headspace. Wipe rims clean, secure lids, and tighten rings to fingertip tightness.
07 -
Either cool jars to room temperature and refrigerate, or submerge in a boiling water canner and process for 15 minutes. After processing, let jars sit in the hot water for 5 minutes, then transfer to a rack or towel to cool undisturbed overnight. Once cool, label and store in a cool, dark place.
