Hi Y'all
My question is, How long should Tofu be Marinated befor cooking? I've had anything from 10 minutes to over night. @_@

Also, does anyone have some good Marinade ideas for Tofu?

Depends on the type of tofu you use - the firmer it is the longer you need to marinate it. I think if you marinated it overnight, though, you'd end up with a soggy mess, even if you used extra firm. For medium firm I marinate about 15 - 20 min. Extra firm is about 40 min.
Ususally I just make some concotion out of soy sauce or ponzu, with garlic, ginger, spices, lemon juice.... whatever I can find kicking about! Worchestershire sauce (I know I spelled that wrong!) with chilis is tasty, and so is orange juice with jamaican jerk sauce. I like my tofu!

if you can find it, mabo tofu mix (try an asian market) is awesome. As for marinating it...I eat it out of the box with a mix of soy sauce and bbq sauce, or with just soy sauce. Not for everyone, but its pretty good. Just a thought. I would think that soy sauce would be a good marinade. Maybe a little ginger and garlic thrown in.
