Cranberries would not be weird....you can add a bit of OJ in the hot water to help mesh the two flavours along. What about slivered almonds? Add canned or fresh poultry to go with the cranberry - thinking Thanksgiving - for the meat eaters in your house? Date/Fig & nuts?
I like using lemon juice, green onions, diced tomatoes, bean sprouts and chick peas - kinda like my own hm version of tabbouleh minus the over abundance of herbs. I'm more of a savory type person though.
Go Thai - lime juice, finely chopped peanuts, bean sprouts, sesame oil and finely diced ginger. Fish sauce optional.
