Ingredients

1 large egg
1 tbsp Dijon mustard
1 tbsp white wine vinegar
1 cup olive oil
1 tsp lemon zest
1 tbsp fresh lemon juice
1/4 cup fresh basil leaves, finely chopped
1/2 tsp salt
1/4 tsp black pepper

Step-by-step Instructions

Start by cracking the egg into a medium bowl. Add the Dijon mustard and white wine vinegar, then whisk everything together until smooth. This is your base.

Next, it's time to emulsify. Begin by adding the olive oil very slowly. At first, just a few drops while whisking vigorously. Once the mixture begins to thicken, you can add the oil in a thin, steady stream, continuing to whisk until fully incorporated and creamy.

Now, it's time to flavor. Stir in the lemon zest, lemon juice, and chopped basil. Sprinkle in the salt and black pepper, then give it a good mix until everything is well combined.

Finally, taste your mayonnaise. Adjust the seasoning if necessary — a little more salt or lemon juice can make a big difference.

Tips & Tricks

  • If your mayonnaise isn’t thickening, try adding a splash of cold water to help the emulsification process.
  • Ensure all ingredients are at room temperature before starting; this helps them blend more easily.
  • Use a balloon whisk for better aeration and a smoother texture.

Serving Suggestions

This mayonnaise is fantastic as a spread on gourmet sandwiches or burgers. It also pairs beautifully with grilled chicken or fish, adding a bright, fresh flavor. Try it as a dip for roasted vegetables or as a base for a zesty potato salad.

Frequently Asked Questions

Can I use a food processor instead of whisking by hand?
Yes, a food processor can make the emulsification process quicker and easier, but whisking by hand gives you more control over the texture.
How long can I store this mayonnaise?
Store it in an airtight container in the refrigerator for up to one week.
Can I use dried basil instead of fresh?
Fresh basil is recommended for the best flavor, but in a pinch, you can use dried. Just use about one-third of the amount, as dried herbs are more concentrated.
