For a sweet tofu mayonnaise try adding some sugar…
16 oz silken tofu
1/2 oz natural sugar
1/2 oz cornstarch
1/2 tsp dry mustard
1/8 tsp salt
1 pinch cayenne
2 Tbsp fresh lemon juice
1 Tbsp cider vinegar
Drain the water off the tofu and put it in a food processor. In a small dry bowl, weigh the natural sugar and cornstarch. Add dry mustard, salt, and cayenne to the bowl, then transfer the dry ingredients to the food processor.
Begin to process tofu and dry ingredients. With the machine running, add the lemon juice and cider vinegar down the feed tube. (If you are using frozen lemon juice cubes, put them in with the tofu.) Continue to process until mixture is very smooth. Stop the machine once or twice to scrape down the sides.
Cover and refrigerate. If the mayo separates in the refrigerator, stir it before using.
