Step 1

In the container of a food processor or in a deep bowl combine the eggs, vinegar, lemon juice, mustard powder and salt.

Step 2

Set the food processor on medium speed, or using a immersion blender in a deep bowl, very slowly drizzle in the oil while it runs and blends in the oil and thickens up. You may need to scrape the sides of the bowl once to ensure it is all combined.

Step 3

Transfer to a sealed container and store this in the fridge for up to two weeks. Enjoy this in sandwiches, burgers, dressings and more!
