Water method is pretty spot on. Definitely in the 250-300+ range for the seed amount. Much longer than 4 hours, I'd say 12-16. Refrigerated. Garlic isn't needed, IMO, though it might help the earthy taste. It's certainly hard to strain, it's a pretty meaty drink to down. Earthy.
You HAVE to use untreated seeds. Personally, never heard of "washing" them, I just always looked for untreated, all natural. Buying in the small, retail packages, is pointless.
Cheers.
