The sauce doesn’t need to be cooked?

No, you don't cook the cranberries. The salad is crisp, but chopping the cranberries means they don't need to be softened.

My "family" recipe for cranberry relish is off the back of the Ocean Spray bag! Very similar except there isn't any jello, just cranberries, sugar and an orange. I used to use a meat grinder and grind the cranberries and orange sections together, then add sugar to taste. Now, my food processor does a similar task, I just have to watch to make sure the cranberries and orange isn't turned into a paste.

So,looking at the recipe, I see that the Jello will thicken it up. Maybe that makes it easier to think of.

My similar recipe is called cranberry 'relish' not salad...or sauce.

My family has a similar recipe, and it is not cooked.
