Start by measuring out all your ingredients. Having everything ready will make the process smooth and efficient.
In a mixing bowl, add 1 cup of mayonnaise and 1 teaspoon of ancho chili powder. Stir them together until the chili powder is fully incorporated.
Next, add the 2 small minced garlic cloves to the bowl. Mix well to ensure the garlic is evenly distributed throughout the aioli.
Pour in 1 teaspoon of unseasoned rice vinegar. Stir until smooth.
Taste your Ancho Aioli and adjust the seasoning if necessary. You can add more chili powder for heat or extra garlic for a bolder flavor.
Refrigerate the aioli for at least 30 minutes to allow the flavors to meld. Serve it chilled as a dip or spread on your favorite dishes.
