In a medium mixing bowl, combine 1 cup of mayonnaise, 2 tablespoons of freshly grated garlic, 2 tablespoons of fresh lemon juice, ½ teaspoon of salt, ½ teaspoon of sugar, and ¼ teaspoon of ground black pepper. Using a whisk, ensure all the ingredients are evenly mixed.

Continue whisking the mixture for about 1-2 minutes until it becomes smooth and cohesive.

Cover the bowl with plastic wrap and place it in the refrigerator for at least 15 minutes.

Once chilled, give the garlic aioli a quick stir before transferring it to a serving bowl.
