When it comes to frying, the choice of coating can make all the difference in the world. Two popular options for coating fried foods are cornstarch and flour. While both can produce delicious results, they have distinct differences in terms of texture, flavor, and overall performance. In this article, we’ll delve into the world of cornstarch and flour, exploring their characteristics, advantages, and disadvantages to help you decide which one is better for frying.
Understanding Cornstarch and Flour
Before we dive into the comparison, let’s take a closer look at cornstarch and flour.
Cornstarch: A Brief Overview
Cornstarch is a fine, white powder extracted from the endosperm of the corn kernel. It’s a popular thickening agent in many recipes, particularly in Asian cuisine. Cornstarch is composed of long chains of glucose molecules, which are responsible for its thickening properties.
Flour: A Brief Overview
Flour, on the other hand, is a powder made from grinding grains, nuts, or seeds. Wheat flour is the most commonly used type of flour for frying. It’s a complex mixture of carbohydrates, proteins, and other compounds that provide structure and texture to baked goods and fried foods.
Texture and Crunchiness
One of the most significant differences between cornstarch and flour is the texture they produce when fried.
Cornstarch: Light and Crispy
Cornstarch produces a light, crispy coating that’s perfect for delicate foods like vegetables, seafood, and poultry. When fried, cornstarch forms a rigid, glass-like structure that shatters in your mouth, releasing a burst of flavor. This texture is often referred to as “tempura-like.”
Flour: Heavier and Crunchier
Flour, on the other hand, produces a heavier, crunchier coating that’s better suited for heartier foods like meats and root vegetables. When fried, flour forms a more rigid, bread-like structure that’s often associated with traditional fried foods like fried chicken and doughnuts.
Flavor and Aroma
Another important consideration when choosing between cornstarch and flour is the flavor and aroma they impart to fried foods.
Cornstarch: Neutral Flavor
Cornstarch has a neutral flavor that won’t affect the taste of your food. This makes it an excellent choice for delicate flavors that you don’t want to overpower.
Flour: Nutty Flavor
Flour, particularly wheat flour, has a nutty, slightly sweet flavor that can enhance the taste of fried foods. However, this flavor can also overpower delicate ingredients, so use it sparingly.
Adhesion and Coating
The ability of cornstarch and flour to adhere to food and form a uniform coating is crucial for achieving the perfect fried texture.
Cornstarch: Excellent Adhesion
Cornstarch has excellent adhesion properties, which make it ideal for coating delicate foods. It forms a strong bond with the food’s surface, ensuring a uniform coating that won’t fall off during frying.
Flour: Good Adhesion
Flour also has good adhesion properties, but it can be more prone to falling off during frying, especially if the food is not properly dredged. To improve adhesion, you can mix flour with other ingredients like cornstarch or eggs.
Health Considerations
When it comes to frying, health considerations are essential. Both cornstarch and flour have their pros and cons in this regard.
Cornstarch: Gluten-Free and Low in Calories
Cornstarch is gluten-free, making it an excellent choice for those with gluten intolerance or sensitivity. It’s also relatively low in calories, with approximately 30 calories per tablespoon.
Flour: High in Calories and Carbohydrates
Flour, particularly wheat flour, is high in calories and carbohydrates. A single tablespoon of all-purpose flour contains around 60 calories and 12 grams of carbohydrates.
Conclusion
So, is cornstarch better than flour for frying? The answer depends on the type of food you’re frying and the texture you’re aiming for. Cornstarch is ideal for delicate foods that require a light, crispy coating, while flour is better suited for heartier foods that need a crunchier exterior.
When to Use Cornstarch:

Ultimately, the choice between cornstarch and flour comes down to personal preference and the specific requirements of your recipe. By understanding the characteristics, advantages, and disadvantages of each, you can make informed decisions and achieve the perfect fried texture every time.
Additional Tips for Frying with Cornstarch and Flour
- Always use the right ratio of coating to food. Too little coating can result in a weak, fragile exterior, while too much can make the food greasy and heavy.
- Experiment with different seasonings and spices to enhance the flavor of your fried foods.
- Use the right type of oil for frying. Peanut oil, avocado oil, and grapeseed oil are excellent choices for their high smoke points and mild flavors.
- Don’t overcrowd the pot or deep fryer. Fry in batches to ensure that each piece of food has enough room to cook evenly.
By following these tips and choosing the right coating for your fried foods, you’ll be well on your way to creating delicious, crispy, and mouth-watering dishes that will impress even the most discerning palates.
What is the main difference between using cornstarch and flour for frying?
The primary difference between using cornstarch and flour for frying lies in their composition and how they interact with food. Cornstarch is a pure starch extracted from corn, whereas flour is a mixture of starch, protein, and fiber. This difference affects the texture and crispiness of the fried food. Cornstarch produces a lighter, crisper coating, while flour can result in a heavier, more doughy coating.
Another significant difference is that cornstarch is gluten-free, making it an excellent option for those with gluten intolerance or sensitivity. In contrast, flour contains gluten, which can be a concern for individuals with gluten-related disorders. When choosing between cornstarch and flour for frying, it’s essential to consider the type of food being fried and the desired texture and flavor.
Is cornstarch better than flour for frying in terms of crispiness?
Cornstarch is generally considered better than flour for achieving a crispy coating when frying. This is because cornstarch is a pure starch that, when mixed with a liquid, forms a smooth, even batter. When fried, this batter produces a crunchy, golden-brown coating that is less likely to become greasy or soggy. In contrast, flour can produce a coating that is more prone to becoming soft or doughy, especially if the food is overcooked or if the wrong type of flour is used.
The crispiness of cornstarch can be attributed to its ability to gelatinize quickly when heated, creating a rigid and crunchy texture. This makes cornstarch an ideal choice for frying foods that require a light, airy coating, such as tempura or fried vegetables. However, it’s worth noting that the type of cornstarch used can affect the crispiness of the coating, with some types producing better results than others.
Can I use cornstarch as a substitute for flour in all frying recipes?
While cornstarch can be used as a substitute for flour in some frying recipes, it’s not always a 1:1 substitution. Cornstarch has a different composition and behavior than flour, which can affect the final texture and flavor of the dish. In general, cornstarch works well as a substitute for flour in recipes that require a light, crispy coating, such as tempura or fried vegetables.
However, in recipes that require a more robust or chewy coating, such as fried chicken or doughnuts, flour may be a better choice. Additionally, some recipes may require a combination of cornstarch and flour to achieve the desired texture and flavor. It’s essential to experiment with different ratios of cornstarch to flour to find the perfect balance for your specific recipe.
How do I mix cornstarch with liquid to create a smooth batter for frying?
To mix cornstarch with liquid and create a smooth batter for frying, it’s essential to follow a few simple steps. First, mix the cornstarch with a small amount of cold liquid, such as water or broth, until the cornstarch is fully dissolved. This helps to prevent lumps from forming in the batter.
Next, gradually add more liquid to the mixture, stirring constantly to prevent lumps from forming. The ideal ratio of cornstarch to liquid will depend on the specific recipe and the desired consistency of the batter. A general rule of thumb is to use 1 part cornstarch to 2-3 parts liquid. It’s also essential to rest the batter for a few minutes to allow the cornstarch to fully gelatinize, resulting in a smooth and even coating.
Can I use cornstarch to fry foods that require a thick, heavy coating?
While cornstarch can be used to create a thick and heavy coating for frying, it’s not always the best choice. Cornstarch is a light and delicate starch that is best suited for creating a crispy, airy coating. If you’re looking to create a thick and heavy coating, flour or a combination of flour and cornstarch may be a better option.
However, if you still want to use cornstarch to create a thick coating, you can try mixing it with a small amount of flour or other starches to add bulk and texture. You can also experiment with different ratios of cornstarch to liquid to achieve the desired consistency. Keep in mind that using cornstarch to create a thick coating can result in a slightly different texture and flavor than using flour or other starches.
Is cornstarch healthier than flour for frying?
Cornstarch and flour have different nutritional profiles, which can affect their healthiness for frying. Cornstarch is a pure starch that is low in calories, fat, and protein. It is also gluten-free, making it an excellent option for those with gluten intolerance or sensitivity.
In contrast, flour is a mixture of starch, protein, and fiber, which can make it higher in calories and fat than cornstarch. However, flour also contains more nutrients, such as iron, B vitamins, and fiber, which can make it a healthier option in some cases. Ultimately, the healthiness of cornstarch versus flour for frying depends on the specific recipe, cooking method, and ingredients used.
Can I store leftover cornstarch batter in the fridge or freezer for later use?
Yes, you can store leftover cornstarch batter in the fridge or freezer for later use. However, it’s essential to follow proper storage and handling procedures to prevent the batter from becoming contaminated or spoiled.
If storing the batter in the fridge, make sure to keep it in an airtight container and use it within a day or two. If storing the batter in the freezer, mix it with a small amount of oil or fat to prevent it from becoming too thick and icy. Frozen cornstarch batter can be stored for several months and thawed when needed. When reheating the batter, make sure to stir it well and adjust the consistency as needed to achieve the desired texture.
