In a medium mixing bowl, add 1 cup of mayonnaise, 2 minced garlic cloves, 1 tablespoon of freshly squeezed lemon juice, 1 teaspoon of cayenne pepper, 1/4 teaspoon of salt, and 1/4 teaspoon of freshly ground pepper. Using a whisk, mix the ingredients together until well combined, ensuring there are no lumps and the texture is smooth and creamy—this will take about 1-2 minutes.

Continue whisking the mixture for an additional minute until the spicy aioli reaches a creamy consistency. You'll know it's ready when the sauce appears velvety and uniform in color.

Once your spicy aioli is well mixed, cover the bowl with plastic wrap or transfer it to an airtight container. Refrigerate for at least 30 minutes, allowing the flavors to meld together beautifully.

After chilling, remove the spicy aioli from the refrigerator and give it a quick stir to recombine any separation. Serve it generously on sandwiches or as a dip.
