Wash and drain the cranberries, and place in a nonreactive saucepan. Add water, sugar, orange zest, and sea salt. Bring to a boil, then reduce heat so that mix simmers gently. Cook about 10 minutes, stirring occasionally, until most of the cranberries have burst. I like to leave a few whole berries remaining. When the sauce has thickened and everything smells amazing, remove from heat and let cool a bit. Remove the tea bag or cheesecloth bundle and squeeze out any remaining liquid. Discard spices.
