In a small bowl, add the mayonnaise, pressed garlic, lemon juice salt, pepper, oil, and Dijon mustard.
Use a whisk to combine everything thoroughly and serve chilled.
Notes
Use full fat mayonnaise- This adds richness and a creamy texture to the sauce. Low-fat doesn't bring the same qualities.
Freshly press the garlic- Use a garlic press to freshly press the garlic so it's smooth and easily incorporates into the aioli.
Use fresh lemon juice- Concentrated lemon juice doesn't have the same scent or flavor of fresh lemon zest and juice. Use a juicer to get the most flavor for your aioli.
Make extra- This sauce stores well so make a double batch to use for later. A tightly lidded container is best for storage.
