Introduction
French fries are a beloved snack, but getting them perfectly crispy can be a challenge. Many people swear by using cornstarch to achieve that coveted crunch, but is it really the key to crispy fries? In this article, we will explore the science behind using cornstarch on fries, its benefits and drawbacks, and alternative ingredients that can make your fries crispy.
What is cornstarch?
Cornstarch is a fine white powder made from the starch of corn kernels. It is commonly used as a thickener in soups, sauces, and gravies, and is also a popular ingredient in baking. Cornstarch is gluten-free and has a neutral flavor, which makes it a versatile ingredient in many recipes.
How does cornstarch affect french fries?
Cornstarch can be used as a coating for french fries to give them a crispy texture. When the cornstarch is heated, it forms a barrier around the fries that prevents moisture from escaping. This creates a crispy exterior while keeping the inside soft and fluffy. The cornstarch also helps to absorb excess oil, which can make the fries greasy.
The science behind crispy french fries
The secret to crispy french fries lies in the Maillard reaction, a chemical reaction that occurs when amino acids and sugars are heated together. This reaction creates the golden-brown color and crispy texture that we associate with fried foods. By adding cornstarch to the fries, we can create a barrier that allows the Maillard reaction to occur more efficiently, resulting in crispier fries.
Benefits of using cornstarch
Using cornstarch on french fries has several benefits. It creates a crispy texture without making the fries greasy, and it also helps to absorb excess oil. Cornstarch is also gluten-free, which makes it a good option for people with gluten intolerance or celiac disease.
Drawbacks of using cornstarch
While cornstarch can make your fries crispy, it can also make them taste slightly powdery if too much is used. It can also be messy to work with, as the powder tends to stick to everything. Additionally, some people prefer the taste of fries without cornstarch.
Other ingredients that can make french fries crispy
If you don’t want to use cornstarch, there are other ingredients that can make your fries crispy. One option is to use rice flour, which creates a similar barrier around the fries. Another option is to add a small amount of vinegar to the cooking oil, which helps to break down the starch in the fries and create a crispy texture.
Tips for using cornstarch on french fries
To use cornstarch on your fries, start by cutting the potatoes into thin strips and soaking them in cold water for at least 30 minutes. This helps to remove excess starch and prevent the fries from sticking together. Then, pat the fries dry with a paper towel and toss them in a mixture of cornstarch, salt, and pepper. Shake off any excess cornstarch and fry the fries in hot oil until golden brown.
How to make crispy french fries without cornstarch
If you prefer not to use cornstarch, you can still make crispy french fries. One method is to use a double-frying technique, where you fry the fries once at a lower temperature to cook them through, then again at a higher temperature to create a crispy exterior. Another option is to sprinkle the fries with a mixture of salt, garlic powder, and paprika before frying, which creates a flavorful crust.
Conclusion: Is cornstarch the key to crispy french fries?
While cornstarch can certainly help to make your fries crispy, it is not the only way to achieve that perfect crunch. The key is to create a barrier around the fries that allows the Maillard reaction to occur, which can be done with a variety of ingredients. Experiment with different coatings and techniques to find the method that works best for you.
