  • 1 large egg room temperature
  • ½ teaspoon ground mustard
  • 1 tablespoon white vinegar
  • ¼ teaspoon salt plus more to taste
  • ½ cup canola oil or any other neutral-tasting oil
  • ½ cup truffle oil
  • 1 teaspoon lemon juice


  • Blend.  In a food processor, blend the egg on high for 20 seconds.  Add the ground mustard, vinegar, and salt.  Cover and blend on high speed for another 20 seconds.
  • Slowly add oil.  Scrape down the sides of the food processor.  On low speed, add a few drops of oil at a time until the mixture thickens.  Increase the speed to high and add the oil in a very slow, steady stream.
  • Season to taste.  Scrape down the sides of the food processor again.  Add lemon juice and salt to state and blend on high speed for 5 to 10 seconds to incorporate.  Store in an airtight container in the refrigerator for up to two weeks.


  • For best results and thick creamy aioli, use room temperature ingredients especially the egg.
  • The addition of lemon juice and extra salt is up to you.
  • Store in the fridge for up to two weeks.
