Um, I don't know. Perhaps try a little bit first before you put it into the whole bowl? Then, if it tastes not quite the thing you haven't compromised the entire dish. The coucous should substitute for the cracked wheat ok though. Nice bit of lateral thinking there NMFD.

And if you can find a tiny bit of fresh mint, chop it nice and fine and sprinkle it through - not too much - just enough to leave a tingle in the mind. Have fun with your potluck party.
