One of the biggest mistakes people make with tofu is to open the package, drain it, and use it. One of the bazillions of things I learned from watching Alton Brown is that you will like your tofu more if you press it first.
To press tofu, you'll need a pound block of firm or extra firm tofu, at least four paper towels, two plates, a couple of heavy cans, and about 20-30 minutes at a minimum.
STEP ONE: CUT
Halve the tofu lengthwise. Just bisect it through the short parts of the rectangle, taking care to cut evenly.
