What main ingredient is used to create the Truffle potato croquettes?

The primary ingredient used in the preparation of Truffle potato croquettes is regular potatoes. This choice is fundamental to the dish since regular potatoes provide the desired texture and flavor that are characteristic of traditional croquettes. They are starchy, allowing for a crispy exterior when fried, while remaining soft and creamy on the inside, which contributes to the overall appeal of the dish. The addition of truffle, often in the form of truffle oil or shaved truffles, elevates the flavor profile and enhances the richness in combination with the natural earthiness of the potatoes. The other ingredient choices do not align with the classic recipe for this particular dish, which relies heavily on the qualities of regular potatoes.
