Today, I'm sharing my lacto-fermented mayonnaise. I combined two recipes to create a mayo that worked with what I already had in my pantry. Sometimes the pantry determines what one can do, wouldn't you agree? 😉
You might wonder why a lacto-fermented mayonnaise? Nourishing Traditions has the answer:
“Homemade mayonnaise imparts valuable enzymes, particularly lipase, to sandwiches, tuna salad, chicken salad, and many other dishes and is very easy to make in a food processor. The addition of whey [for lacto-fermentation] will help your mayonnaise last longer, adds enzymes and increases nutrient content.”
I have read where people don't like the mayo in Nourishing Traditions that much. We hadn't had mayonnaise for many years (due to my son's previous egg allergy), so I figured we might not have any mayo-taste memories for comparison. The Nourishing Traditions mayo uses olive oil for the oil, which is admittedly a pronounced flavor, but we liked it (and it was amazing in our egg salad). If I'd had some sesame oil (as called for in Kelly's recipe), I would have used some sesame oil (or another mild oil) in place of the olive oil for balancing. So feel free to do that.
- 3 organic or pastured egg yolks
- 1 teaspoon Dijon mustard or Erin’s lacto-fermented mustard
- 1 1/2 tablespoons raw apple cider vinegar
- 1 tablespoon whey or use about 1/32 to 1/16 teaspoon of a veggie starter culture like this
- sea salt to taste (about 8 pinches for me)
- 1 cup extra virgin olive oil extra virgin, or any combination of oils you’d like*
With a food processor...
Combine egg yolks, mustard, vinegar, whey, and salt in a food processor bowl.
Blend well, about 30 seconds.
With the food processor running, add the olive oil in as slow a drizzle as possible. It will emulsify into mayonnaise. It took me about 5 minutes, at least, to slowly pour in the 1 cup of olive oil and complete the emulsification.
Adjust salt to taste.
To lacto-ferment and help the mayonnaise last longer, leave it out in an air-tight jar or container at room temperature for 7 hours.
With a stick blender...
Put all ingredients but oil in a quart jar.
Blend briefly with the stick blender.
Then run the stick blender while adding a little oil.
Stop adding oil and keep blending to make sure it emulsifies.
Repeat with more oil until all the oil is in and emulsified into mayonnaise.
Adjust salt to taste.
