Print Recipe
Ingredients
1 Whole Egg, room temperature
2 tsp Lemon Juice, room temperature
1 tsp Spicy Brown or Dijon Mustard, room temperature
1/4 tsp Sea Salt
1 C. Avocado Oil (or any neutral flavored oil)
1 tsp Vinegar, optional (white wine vinegar, apple cider vinegar, etc.)
Instructions
  1. 1
    IMPORTANT: Make sure all ingredients are at ROOM TEMPERATURE before blending. This step is crucial for proper emulsification.
  2. 2
    Using a tall, skinny wide-mouth mason jar or other comparable size (jar should be only slightly wider than the head of your immersion blender), add all ingredients, except the oil. Pour the oil into the jar and wait a few seconds for the ingredients to separate; the oil should be on top.
  3. 3
    Place the immersion blender firmly against the bottom of the jar and blend on high for 20 seconds or until the mixture begins to emulsify. Then you can slowly start to move the blender up and down until everything is fully emulsified.
  4. 4
    Once fully emulsified, remove the blender, give the mayonnaise a good stir, and transfer mayo to a container with a lid. Place in the fridge immediately. This will stay fresh in the fridge for up to 7 days. Not suitable for freezing.
Notes: IMPORTANT: Make sure all ingredients are at ROOM TEMPERATURE before blending. This step is crucial for proper emulsification.
Notes: BLENDER METHOD: If you do not have an immersion blender, this can be made in a regular blender or food processor. However, the process is a bit different. Add the egg and process for ~20 seconds. Add mustard, vinegar, and salt, then process ~20 seconds more. Then, with the machine running, VEER SLOWLY drizzle in the oil in tiny drops. You should start to see the emulsification take place. When that happens, continue adding the oil in a very slow, steady stream until the mayo is thick and creamy.
