The Core Components of a Cheese Curl
At its most basic, a cheese curl is an extruded corn snack coated with a cheese-flavored powder. This simple definition, however, belies a complex process involving several key ingredients. The foundation of the snack is cornmeal, specifically a very finely textured variety. This is mixed with water to form a dough, which is then sent to the next stage of the manufacturing process.
The Flavor-Packed Coating
While the cornmeal provides the bulk and structure, the unmistakable taste comes from the flavored coating. This isn't a single ingredient but a blend of various components. Major brands commonly use a mix of real cheese and artificial flavorings to achieve a consistent, craveable taste. Some ingredient lists reveal the use of multiple dairy derivatives, including:
- Cheddar cheese (powdered form)
- Whey and whey protein concentrate
- Buttermilk solids
- Maltodextrin
- Artificial and natural flavors
- Monosodium glutamate (MSG) as a flavor enhancer
In addition to the flavorings, various food colorings, such as Yellow 5 and Yellow 6, are used to achieve the signature vibrant orange hue.
The Role of Oils
Vegetable oil serves a dual purpose in the production of cheese curls. First, it can be part of the cooking process itself, as some varieties are fried. Secondly, and more commonly, oil is sprayed onto the puffed corn snack after it is cooked but before it is coated with the flavoring powders. This oil acts as an adhesive, ensuring the cheesy seasoning sticks to the curls. Common oils used include corn, canola, soybean, and sunflower oil.
The Manufacturing Magic: Extrusion and Flavor Application
What makes a cheese curl light, airy, and crunchy? The answer is the extrusion process. This industrial technique is fundamental to the creation of many puffed snack foods.
The Extrusion Process
- Dough Creation: Finely ground cornmeal is mixed with water to form a damp dough.
- Pressure and Heat: The dough is fed into an extruder, a machine that cooks, heats, and pressurizes the mixture.
- Shaping: The pressurized dough is pushed through a small hole in a metal plate called a die. As the hot, moist dough exits the die, the sudden drop in pressure causes the moisture to flash into steam, puffing up the cornmeal. The shape of the die determines the final form, whether it's a curl, ball, or puff.
- Collette Formation: The un-seasoned, puffy pieces are called "collettes".
Cooking and Coating
After extrusion, the cooking method varies by product. Some brands bake the collettes, resulting in a lighter, less greasy snack. Others opt for frying, which creates a denser, crunchier texture. Once cooked, the still-warm collettes are moved to a large rotating drum.
First, they are sprayed with a fine mist of vegetable oil. Then, the cheese powder and other seasonings are applied, clinging to the oily surface as the drum tumbles. This automated process ensures an even distribution of flavor.
Comparison: Baked vs. Fried Cheese Curls
| Feature | Baked Cheese Curls (e.g., Herr's Baked) | Fried Cheese Curls (e.g., Jax) |
|---|---|---|
| Cooking Method | Baked in an oven after extrusion | Fried in vegetable oil after extrusion |
| Texture | Lighter, airier, and more brittle | Denser, crispier, and often greasier |
| Mouthfeel | Melts in the mouth more easily | Requires more chewing, richer feel |
| Appearance | Often have a more uniform, smooth finish | Can have a more rugged, slightly oily look |
| Flavor Distribution | Seasoning can feel slightly drier | Oil base helps seasoning adhere more intensely |
The Evolution of the Cheesy Snack
The origins of the cheese curl are a fascinating tale of industrial innovation. The accidental discovery of puffed corn from a livestock feed machine by Edward Wilson at the Flakall Corporation was the starting point. This led to the Adams Corporation's commercialization of the Korn Kurl in 1946. The Frito Company introduced its own version, Cheetos, in 1948, which eventually became a dominant force in the market. Over the decades, brands have refined their recipes, but the core formula of extruded corn and cheese seasoning has remained a constant.

Conclusion
So, what are cheese curls made out of? The essential ingredients are simple: cornmeal, vegetable oil, and a blend of cheese powder and seasonings. The manufacturing process, particularly the extrusion that gives them their distinctive puff and shape, is what truly defines the snack. From an accidental byproduct to a mass-produced favorite, the cheese curl's journey is a testament to the ingenuity of food science. Understanding what goes into these treats adds a layer of appreciation for the crispy, cheesy snack that leaves us with that famous orange residue on our fingertips.
