Notes
I recommend starting with ½ cup sugar, then adding more if desired. The amount of sugar you will need will depend on how sweet your apple and orange are, as well as your own personal taste. Less sugar with yield a more tart relish, while more sugar will yield a sweeter, less tart relish. I used one full cup.Choose a full-flavored apple, such as Granny Smith, Fuji, Cortland, or Honeycrisp (which is what I used).This is a flexible recipe.
