What ingredients are found in crispy yam fries?

The crispy yam fries typically contain ingredients that give them their distinct flavor and texture. The correct choice includes mustard, egg, soy, and sulphites, which can all be used in the preparation process. Mustard may be utilized for seasoning, providing a tangy flavor. Egg can be used in battering or coating, adding to the crispiness of the fries during cooking. Soy, potentially in the form of soy sauce or another soy ingredient, can enhance the flavor profile. Sulphites may be used as preservatives to maintain the freshness and color of the fried items.

The other options include combinations of ingredients that are not commonly associated with crispy yam fries, such as dairy and seafood, which are not typical in a dish focused on yam preparation.
