Corn Starch vs Flour

Corn Starch vs. Flour: The Main Differences Between Two Baking Staples

Although they look similar, there is a difference between cornstarch and flour. Flour is typically from wheat but can also come from various sources. Corn starch, on the other hand, comes specifically from corn. Another difference is that corn starch is gluten-free, but flour is not. Let's take a look at more of the differences below.

Corn Starch vs. Flour: What are the Differences?

Both cornstarch and flour are great resources for baking, household uses, and more. They are also typically essential ingredients in baking and are starches. However, there are some basic differences.

Corn starch is explicitly from the endosperm of corn. It is also a delicate and white powdery substance. 

On the other hand, flour is usually from wheat. 

Both cornstarch and flour are typically thickening agents. Yet, the degree to which they are useful in this area also varies. 

Overall, cornstarch is better when it comes to being a thickening agent. It does not have an odor or any flavor. Likewise, when cornstarch is added to the gravy or soup, it becomes gel-like. The gel is transparent and does not clump together. 

On the other hand, flour is more of an opaque and white color. It can even be cloudy. Another difference is flour's tendency to clump together, especially when added to the liquid. 

Flour has gluten and corn starch does not. Since corn starch doesn't contain gluten, it is a more ideal thickening agent than flour.

There are varieties of flour and starches available on the market today. Whether you are looking for a gluten-free option, grain, or something else entirely, there are many to choose from.

The Flavor of Corn Starch

Corn starch is an ideal additive for many reasons. However, one of the favorite characteristics of corn starch is that it has no flavor and no aroma. This works in corn starch's flavor, making it very versatile and adaptable. This starch can be great as a thickening agent in any soup, gravy, stew, or baking. 

The Flavor of Flour

The flavor of flour will vary depending on the type of grain. Some flour has no flavor at all. This happens when the flour undergoes more processing. Other times, the flour will taste salty or nutty. Usually, when the flour is wheat or bran flour, the nutty and salty taste will be present. The nutty flavor is usually present when most wheat kernel is not removed. Flour is mild in taste and does not drastically change your food's flavor profile.

Nutritional Profile

Regarding nutritional profile, corn starch, and flour vary a bit from each other. Take a look at the comparison chart below to see how they stack up against one another.

Corn Starch vs Flour Nutritional Facts

The Use of Corn Starch

Corn starch has a variety of versatile uses. This starch is popular as a thickening agent in gravies and stews. Yet, did you know it can also be great to use as an all-natural household aid? 

Corn starch is often utilized as dry shampoo, skin relief, or deodorant! It can dry up and absorb moisture. The fact that it is odorless is a huge plus as well.

The Use of Flour

Flour is often a base used during baking. Pies, bread, cakes, muffins, and more all use flour. It can also be great for coating meats.

Like corn starch, flour has household uses as well! These include dry shampoo, repelling ants, DIY glue, and making homemade playdough for your kids.

What is Corn Starch?

We know it is a great thickening agent and fantastic for household uses; however, what exactly is corn starch? Corn starch is made from the endosperm of corn. Many qualities make corn starch excellent and versatile. 

First, corn starch is gluten-free. The fact that it doesn't carry any gluten and has two times the thickening power than flour makes it a perfect thickening agent. 

Corn starch is a white powdery substance that is flavorless, odorless, and versatile. It also keeps the batter from lumping together. 

When it comes to nutrition, corn starch only carries a little. However, don't discount its usefulness. Corn starch is also great as a fried food batter and in baking. It is a staple that is handy when kept in your pantry.

What is Flour?

Flour is a powdery and white substance as well. Yet, instead of corn, it is typically from wheat. 

Flour is what happens when the dry grain goes through a milling process. This process is called pulverizing. Although flour is typically wheat, it can have various sources. These sources include oats, barley, corn, and rice. 

To make flour, any part of the wheat can be used. These are the endosperm, bran, or germ. 

All-purpose white flours typically only contain the endosperm. It has carbohydrates, protein, and some oil. Nevertheless, if you have ever made your way through the baking aisle, you know that more than just simple white flour is available. 

Whole grain flour will have the brain still attached. This is the outer part of the grain, which gives whole grain flour a brown color. Whole grains also have a coarser texture than white flour. 

It is possible for flour to still have all three, germ, bran, and endosperm. When this is the case, the flour will have various minerals, fibers, and vitamins. This is because the germ contains most of the grain's nutrients. 

Types of Flour

The most popular type of flour is all-purpose. It is prevalent in many baking recipes, and if you look in your pantry right now, a bag of all-purpose flour will probably be sitting there. That is because it has expansive versatility. All-purpose flour has been stripped of everything except the endosperm of the wheat. It also undergoes bleaching and enriching. Enriching is when the nutrients are put back into the flour because most of it is lost during processing.

All-purpose flour is only one of many types of flour available, though. Self-rising, whole wheat, rice, bread, cake pastry, and unbleached flour are all on the shelves found in grocery stores.

Can You Substitute Corn Starch for Flour?

It is possible to substitute cornstarch and flour as a thickening agent. Corn starch has two times thickening ability. Use two times less cornstarch or two times more flour, depending on which one you are substituting. 

One Last Note

Flour is more likely to be in the average person's pantry.
  • Like the name suggests, corn starch comes from corn. Meanwhile, flour comes from wheat. This difference is important to know if you want to fully understand corn starch vs. flour.
  • While both flour and corn starch work as thickening agents, corn starch is generally considered the better thickener between the two.
