Vegan Japanese Mayo is made using tofu instead of the traditional egg yolks to attain the creamy custard-style mayo. The deep yellow color is achieved with a combination of carrot, and turmeric.
Combine the water, tofu, carrots, poultry seasoning, and turmeric. Stir to combine.
Gently cook over low heat. The goal is to have the carrots tender and most of the liquid reduced.
Place the tofu mixture in a cup, and add the Dijon mustard, red wine vinegar, apple cider vinegar, rice wine vinegar, and EVOO. Using an immersion blender puree until smooth and thick.
Season with the black salt, start with half, mix, and taste. This is a very personal flavor profile, so adjust it to meet your expectations.
Set aside in the refrigerator.
