Using Cornstarch Instead of Flour in French Fries: A Crispier Approach

When it comes to preparing French fries, most cooks use flour for the frying process. However, many curious home chefs wonder if cornstarch is a suitable alternative. This article explores the possibility of using cornstarch instead of flour for making extra crispy fries, along with some tips on achieving the perfect texture and flavor.

The Role of Cornstarch in Fries

While traditional French fries are often associated with the use of flour, especially in the twice-cooking technique, it is indeed possible to use cornstarch to achieve that iconic crispy texture. Cornstarch is commonly used in cooking for its ability to thicken and stabilize sauces, but it can also help in creating a lighter and crispier exterior on fried foods.

One popular method involves mixing equal parts cornstarch and cold water to form a slurry, which is then added to the hot oil during frying. This mixture helps in achieving a crispier result and can enhance the overall texture of the fries. Flour, on the other hand, is often used for its flavor and texture. However, for a purely crispy outcome without adding extra depth, cornstarch is a suitable substitute.

Twice-Cooking Technique with Cornstarch

The twice-cooking technique, a favorite among professional chefs, involves frying the fries twice to achieve the perfect texture. First, the fries are fried at a lower temperature to partially cook them, then they are removed and allowed to drain. Once cooled, they are fried a second time at a higher temperature to achieve the golden brown, crispy exterior.

Incorporating cornstarch into this technique can lead to an even crispier result. The initial fry might not yield the same level of crispiness as using flour, but the final fry with the cornstarch slurry can significantly enhance the texture. Additionally, the cornstarch helps to create a thinner, more crackly outer layer, giving the fries that light, airy texture that many people adore.

Other Uses of Cornstarch in Cooking

Cornstarch is a versatile ingredient with many applications beyond just French fries. For instance, it can also be used to make roux, although it is not ideal for thickening sauces due to its inability to develop distinct flavors.

When making roux, it is generally recommended to use flour as it adds flavor and body to the sauce. However, cornstarch can be used for thickening when you want a clear, smooth sauce. In such cases, use about half the amount of cornstarch by volume compared to flour. This combination ensures that you achieve a thick, shiny sauce without the creaminess that flour can provide.

Conclusion

While flour is the traditional choice for making French fries, cornstarch certainly has its merits. By using a cornstarch slurry in the twice-cooking technique, you can achieve extra crispy fries with a lighter and more airy texture. Whether you are a seasoned chef or a curious home cook, experimenting with cornstarch can open up new possibilities in your French fry recipe.

Remember, cornstarch is primarily used for its thickening properties, rather than flavor, so adjust your recipe accordingly. With a little experimentation, you can create the perfect crispy fries that will delight both your palate and your guests.
