What is your favorite way to bread tofu to use in a stir fry?

I toss it in rice flour before frying it in peanut oil. If you don't have rice flour you can use corn starch.

never heard of breaded tofu....now I am kind of curious if Wondra flour would work...hmmm.....
It is pretty good just fried in oil, as the others have suggested. I have also started marinating tofu in peanut sauce and then grilling it on the George Forman and adding it to the stir-fry later. The tofu gets nice and firm and it cuts down a lot on the oil...

Press the tofu for a while, to drain off some of the water. Dry, cut to size, and shake it in some cornstarch or arrowroot, for a light coating. But I agree with the professor, it's not necessary.

FYI: it should brown nicely without any breading at all, cooked in peanut oil over high heat, and squeezed of excess moisture beforehand.

Look up "agedashi tofu". Its a great traditional way of preparing Firm Tofu.
