I rehydrated because it was the first time I had ever used them for sausage. I didn't want them to suck the moisture out of my sausage. I have used them in other cooking and always rehydrate them.I've used both extensively in jerky making and never rehydrated. Especially good with ground jerky. Onion is powerful but not obnoxious. I use this garlic when I am too lazy to chop fresh.
