Coriander makes a nice herbal tea. Pretty mellow in flavor when brewed. Like chamomile, except, it’s not a narcotic.*
*OK, that may be an excessively strong statement. But I can’t drink chamomile, it makes me fall asleep instantly, have too vivid, disturbing dreams, and have to pee like a racehorse first thing in the morning.
Oh, and …
Has the vanillan crystallized out of the dried out pods as white fluffy crystals? It may be excellent. Otherwise, you might be able to get the flavor out if you soak the beans in booze for a couplea months.
