Right now, I'm trying to figure out if I would put them in the boil or not (as a puree near the end). Since elderberries are supposedly mildly poisonous (!) raw, I'm trying to figure out a possible way to safely incorporate them into the brew without creating any chemical haze (I've read that boiling fruits in the wort tends to create some sort of haze. Anyone know anything about this?).
A couple elderberry wine recipes that I've read say to rehydrate the berries with boiling water, then to juice them, and boil the juice. I reckon this would do the same sort of hazing that putting it in the wort would do? Is it a good idea to use the fruit skins in the secondary? Any ideas?

EDIT: "There are reports of gastrointestinal distress, diarrhea, vomiting, abdominal cramps, and weakness after drinking elderberry juice made from crushed leaves, stems and uncooked elderberries. Notably, the berries must be cooked to prevent nausea or cyanide toxicity." yikes! talk about a risky brew!
