Start by ensuring your egg is at room temperature. This helps in creating a smooth mayonnaise. Place the egg in a mini food processor or blender and pulse until mixed.

Gradually add the oil by adding a few drops at a time, pulsing after each addition. Repeat this process of adding oil and pulsing until all the oil is used.

Adding the oil slowly helps to create a creamy texture. While continuously pulsing, slowly pour in the remaining oil in a steady stream.

As you do this, you'll notice the mixture thickening and becoming creamy.

Once you've achieved your desired consistency, stir in lemon juice, Dijon Mustard, salt, and pepper to taste.

if desired, add any additional ingredients at this point and give everything a good stir with a spatula.

Taste your mayo and adjust seasoning according to your preference by adding more salt, pepper, or lemon juice if needed.

Transfer the homemade mayonnaise into an airtight container and refrigerate for at least 30 minutes to allow flavors to meld together.

Your homemade mayo can be stored in the fridge for up to one week in a glass jar.

Enjoy your delicious homemade mayonnaise!
