The honey is a lot easier to mix if you heat it up in a pan of hot water first.

Use a microplane to zest some of the satsumas, about 2 tsp zest.

Use a food processor to pulse the cranberries until coarsely chopped. Transfer to ~3 qt bowl. I prefer a tall bowl, fits better in my frig.

Peel the satsumas and separate the segments. Remove as much pith as possible. Coarsely chop (try not to lose any juice!) and add to bowl.

Add the zest, honey, onion, and ginger to the bowl. Mix well, cover with plastic wrap, and refrigerate a few hours or preferably over night.
