VEGAN VERSION: If making a vegan version with silken tofu– replace the mayo with ½ a package silken tofu ( about 6 ounces or 165 grams), leave out the water and add 2 tablespoons olive oil. Increase salt to ½-¾ teaspoon, add ¼ teaspoon sugar and 1 teaspoon apple cider vinegar (in addition to the lime) and place all in a food processor, blending until smooth and creamy. Use a canned chipotle pepper ( or half of one!) or just a teaspoon or two of the adobo sauce from the can, for the best flavor. Adjust salt, heat and lime.
I use Mori-Nu Organic Silken Tofu– Firm or Extra Firm Tofu – ½ of a 12.5 ounce package.
