Whisk mayonnaise, Sriracha sauce, lime juice, crushed garlic, and sea salt in a small bowl.
Taste and adjust with more Sriracha or salt, if needed. To make the Sriracha Aioli spicier, add ⅛ to ¼ teaspoon cayenne pepper.
Use right away or store in an airtight container or condiment bottle in the refrigerator for up to a week.
Notes
Sriracha Aioli can also be prepared in a small food processor. Just add all the ingredients to the food processor bowl and whirl until the ingredients are blended and creamy.
If you are sensitive to spicy flavors, add 1 tablespoon of Sriracha to the mayo at a time, tasting after each addition until satisfied.
The sauce can also be thinned and used as a salad dressing, especially in this oil and vinegar coleslaw!
