Place a clean, lint-free towel on a plate or cutting board. Cut the tofu into 3 or 4 pieces and carefully place on the towel. Let sit for 10 minutes or so, while you gather the other ingredients. **The idea is to reduce the amount of moisture in the tofu as much as possible because we're not adding any thickeners, gums or fats.**
Transfer the tofu to a blender with the dry mustard, lemon juice, vinegar and salt. Blend until smooth. Taste for salt, adding a pinch more if desired. Transfer the mayo to a bowl or glass container, cover, and refrigerate. Use within 3 to 4 days.
