Crusco peppers, also known as Peperoni Cruschi, are a type of dried, crispy pepper that is a specialty of the Basilicata region of Italy. They are made from a specific variety of sweet pepper called Peperone di Senise, which is known for its low moisture content and thin pulp. The peppers are dried and then flash-fried, resulting in a crunchy, slightly sweet, and intensely flavorful snack or ingredient.
