What is the main flavoring ingredient in the sriracha aioli for the egg sandwich?

The main flavoring ingredient in the sriracha aioli for the egg sandwich is sriracha. This unique chili sauce provides the signature spicy and tangy flavor that defines the aioli. Sriracha is made from chili peppers, vinegar, garlic, sugar, and salt, which not only enhances the taste profile of the egg sandwich but also adds a vibrant kick that complements the dish well. While mayo serves as the base for the aioli and garlic adds depth to the flavor, sriracha is the key ingredient that characterizes this particular aioli, making it stand out and integrating its distinct flavors into the sandwich. Lemon juice, while it may offer acidity, does not play the leading role in shaping the overall flavor footing of the aioli compared to sriracha.
