Which sauce is popular in many Panda Express dishes?

Orange sauce is indeed popular in many Panda Express dishes, making it a distinctive flavor profile for the restaurant. It’s famously used in the Orange Chicken dish, one of their signature offerings. This sauce is characterized by its sweet and tangy flavor, incorporating ingredients like orange juice, sugar, soy sauce, and vinegar, contributing to its widespread appeal among customers.

The other sauces, while they may be used in some dishes, do not hold the same iconic status as orange sauce does at Panda Express. Barbecue sauce is less associated with Asian cuisine, making it less prevalent in their menu. Sweet and sour sauce is somewhat popular but does not have the same level of recognition or unique association with a signature dish. Teriyaki sauce, while featured in several items, has a different flavor profile that doesn't define the brand in the way orange sauce does. Thus, orange sauce stands out as a key element of Panda Express’s culinary identity.
