Combine 1 cup of mayonnaise, 1 minced clove of garlic, and 1 tablespoon of lemon juice in a mixing bowl.
Add 1 tablespoon of chipotle powder or adobo sauce into the mixture.
The choice between chipotle powder and adobo sauce depends on your preference for texture and heat.
Season the mixture with a pinch of salt and a pinch of black pepper.
You can always add more later if needed.
Use a whisk to thoroughly mix all the ingredients until the sauce is smooth and well combined.
Transfer the chipotle aioli to an airtight container and refrigerate for at least 30 minutes.
This allows the flavors to meld.
