Step 1Drain the tofu and pat very dry. Cut into 1-inch cubes, transfer to a large piece of cheesecloth, wrap tightly and wring as much liquid as possible out of the tofu.
Step 2Transfer to a large bowl and crumble into small pieces. Stir in the vinegar, lemon juice and 1 tablespoon salt. The mixture should taste quite salty. If it doesn’t, add more salt.
Step 3Return the mixture to the cheesecloth and wrap tightly to form into a block of cheese. Put in a small bowl. Cover with plastic wrap and refrigerate until firm, at least 1 hour. When ready to use, discard excess liquid and crumble the tofu into bits of cheese.
