There are a ton of good vegan mayonnaise recipes out there. But I keep coming back to this recipe I adapted from a vegan camp I went to about ten years ago. It is mild, creamy, and delicious. As usual, I have listed quantities as a guide only. I tend to add in the lemon juice, vinegar and salt at the end, and keep tasting in between each addition. Every batch yields a mayo of a slightly different personality, depending on my mood, and what I am going to use it for. But the quantities I have provided will keep you on the right track. Follow them, and you will get a mayo that you can play with.
