01 - Preheat vegetable oil in a deep fryer or heavy-bottomed skillet to 350°F.
02 - Remove and discard the casings from the boudin sausage. Place the filling in a mixing bowl, add the chopped green onions, and combine thoroughly.
03 - Roll the boudin mixture into 1 1/2-inch balls and arrange them on a tray.
04 - Arrange three shallow bowls: the first with flour, the second with beaten eggs, and the third with breadcrumbs mixed with cayenne pepper, salt, and black pepper.
05 - Roll each ball in flour, dip into the beaten eggs, then coat thoroughly with the seasoned breadcrumbs. For extra crunch, repeat the egg and breadcrumb coating.
06 - Carefully lower the breaded balls into the hot oil in batches. Fry for 3 to 4 minutes until golden brown and crispy. Remove with a slotted spoon and drain on paper towels.
07 - Serve hot alongside Creole mustard or remoulade sauce for dipping.
