Gather Equipment
Use an immersion blender and a tall, narrow container (like a mason jar) for the best results.
Blend the Base Ingredients
Add the egg, lemon juice, vinegar, mustard, and salt to the container. Blend until smooth.
Emulsify the Oil
With the blender running, slowly drizzle in the avocado oil. Gradually adding the oil ensures a thick and creamy consistency. Blend until the mixture reaches a mayonnaise-like texture.
Taste and Adjust
Taste your aioli and adjust the seasoning with additional salt or lemon juice as desired. Blend briefly to incorporate any changes.
Store and Use
Transfer the aioli to an airtight container and refrigerate. It’s best enjoyed within a week.
