Place the garlic, egg yolks, Dijon mustard, salt, and vinegar in the bowl of a food processor.
Run the food processor until everything is well blended, stopping to scrape down the bowl as necessary.
While the food processor is running, slowly stream in the oil until it has been fully incorporated and it starts to look creamy
Taste and adjust the seasoning as needed.
Notes
Storage: Store homemade aioli in an airtight container in the refrigerator for up to 5 days. Store bought aioli will last longer because the raw eggs in homemade versions reduce its shelf life.
