Line a cutting board with enough layers of paper towels to soak up extra water, and place your tofu pieces in single layer on top of the paper towels. Layer more paper towels on top of the tofu and place something flat on top, another cutting board would be perfect. Place enough weight on top of the upper cutting board to put pressure on the tofu without crushing it. I use whatever canned goods I have on hand that will fit on top of the cutting board, but be sure the weight is sufficient to gently remove excess water. Allow the tofu to rest 15 to 30 minutes.
