In a mixing bowl, add 1 cup of mayonnaise, 2 minced garlic cloves, 1 tablespoon of fresh lemon juice, 1 teaspoon of cayenne pepper, 1/4 teaspoon of salt, and 1/4 teaspoon of black pepper. Use a spatula or spoon to ensure all ingredients are well-distributed, creating a smooth and creamy base.

Using a whisk, blend the mixture thoroughly for about 30 seconds at a moderate pace until it becomes creamy and homogenous.

Transfer the aioli into an airtight container or cover the bowl tightly with plastic wrap. Refrigerate for at least 30 minutes, allowing the flavors to meld together beautifully.

After chilling, give your spicy aioli a gentle stir and taste for seasoning adjustments, adding more lemon juice or cayenne if desired.
