Sorullos are made of a mix of hot water, salt, and cornmeal, formed as sticks or logs, then fried or cooked in an olive oil and butter mix. The flavor is usually lightly sweet, but can also be savory. Sorullos are best served hot, and the texture is crisp on the outside and dense and soft in the inside.
Sweet sorullos contain sugar, butter, and hot milk. These sweet sorullos are often filled with cheese such as "Queso de freir" (Spanish for frying cheese), "Queso blanco" (Spanish for white cheese), cheddar or mozzarella.
