Fail-Proof Homemade Mayonnaise

• servings: 1 item
• active time: 10 minutes
• total time: 10 minutes

Ingredients

1 large egg at room temperature

1 tablespoon Dijon mustard

1 tablespoon red or white wine vinegar

1/4 teaspoon kosher salt, or more to taste

1 cup (240ml) neutral flavored oil, grapeseed, safflower or canola are best

1 teaspoon fresh lemon juice, optional

Directions

If you have a large food processor, use the smaller bowl attachment that came with your processor so that the bowl is not too large for the amount of mayonnaise this recipe makes. Not using the smaller bowl can prevent the mayonnaise from emulsifying since the mixture will not have enough contact with the blade.

If you do not the smaller bowl attachment, making the mayonnaise with an immersion blender or by hand are alternatives. Or simply make a larger batch and double the recipe and use the standard bowl attachment. You might find success with a high-speed blender, but based on reviews and comments from readers, using a blender seems to be less fail-proof.

Add egg to the small bowl of a food processor and process for 20 seconds. Add the mustard, vinegar, and salt. Process for another 20 seconds.

Scrape the sides and bottom of the bowl, turn the food processor on then begin to slowly add the oil in tiny drops until about a quarter of the oil has been added (this is critical for proper emulsification).

When you notice that the mixture is beginning to thicken and emulsify, you can be a little less strict. With the processor on, continue to add it slowly, but increase to a very thin stream instead of drops of oil.

When all of the oil has been added, scrape the bottom and sides of the bowl and process for an extra 10 seconds. Taste mayonnaise for seasoning then add salt, lemon juice or extra vinegar to taste.

Note, if the mayo seems too thin, slowly stream in more oil with the processor running until thick.
