Corn has been a staple in many cultures for centuries, providing sustenance and versatility in cooking. Among the various products derived from this golden grain, corn flour and cornstarch stand out for their unique properties and uses. In this article, we will explore how to make corn flour and cornstarch at home, delving into the processes, differences, applications, and nutritional aspects of these two essential ingredients.
Understanding Corn Flour and Cornstarch
Before we dive into the preparation methods, it’s crucial to understand the differences between corn flour and cornstarch. Both come from corn kernels, yet they serve distinct purposes in cooking and baking.
What is Corn Flour?
Corn flour is made from whole corn kernels that are ground finely. It tends to have a slightly coarse texture and is commonly used in various recipes, such as breads, muffins, and pancakes. Its natural sweetness and flavor can enhance the taste of many dishes.
What is Cornstarch?
Cornstarch, on the other hand, is derived from the starchy part of the corn kernel and has a very fine, powdery consistency. It is primarily used as a thickening agent in sauces, gravies, and soups, and it plays a vital role in baking when added to recipes that require lightness and moisture retention.
The Benefits of Making Your Own Corn Flour and Cornstarch
Making corn flour and cornstarch at home has several advantages:

How to Make Corn Flour
The process to create corn flour is straightforward and can be done using minimal equipment. Here’s how to do it in a few simple steps.
Ingredients Needed
- Whole corn kernels (dried or fresh)
- A high-powered blender or food processor
- A fine-mesh sieve or flour sifter
Step-by-Step Process
Step 1: Selecting Your Corn
Start by choosing the right type of corn. While dried corn kernels are preferred for grinding because of their durability, if you’re using fresh corn, ensure it is sweet and free from blemishes.
Step 2: Washing Corn Kernels
If you are using fresh corn, peel the husks and wash the kernels thoroughly to remove any dirt or pesticides. If using dried corn, ensure they are clean and free of any debris.
Step 3: Drying (if necessary)
Fresh corn kernels should be dried if they are too moist. You can do this by spreading them out on a baking sheet and placing them in a dehydrator or a low-temperature oven until dry.
Step 4: Grinding the Corn
Once the corn is ready, place it in your blender or food processor. Start blending in small batches until the kernels are finely ground, resembling a flour consistency. It may take a few minutes, so be patient.
Step 5: Sifting the Flour
After grinding, pour the flour through a fine-mesh sieve to separate any coarse particles. You can re-blend the coarser pieces or set them aside for use in other dishes.
Step 6: Storing the Corn Flour
Store the corn flour in an airtight container in a cool, dark place. It can last for several months when stored properly. For longer shelf life, consider refrigerating or freezing it.
How to Make Cornstarch
Making cornstarch at home involves a slightly different process than making corn flour. The focus here is purely on extracting the starchy portion of the corn.
Ingredients Needed
- Whole corn kernels (preferably dried)
- A blender or food processor
- Water
- A fine-mesh sieve or cheesecloth
- A large bowl
- A flat surface for drying
Step-by-Step Process
Step 1: Soaking the Corn Kernels
Start by soaking your dried corn kernels in water for about 24 hours. This helps soften them and makes extraction easier.
Step 2: Blending
After soaking, drain the corn and place it in a blender. Add water in a 1:1 ratio (1 cup of corn to 1 cup of water) and blend on high speed until you achieve a smooth consistency.
Step 3: Straining
Pour the blended mixture into a fine-mesh sieve or cheesecloth over a large bowl. Press down to extract as much liquid as possible. This liquid contains the starch you will be using for cornstarch.
Step 4: Settling the Starch
Let the starchy liquid sit undisturbed for several hours. The starch will settle at the bottom, while the water will remain at the top.
Step 5: Collecting the Starch
Once settled, carefully pour off the water without disturbing the starch. You can use a spoon or spatula to scrape the starch off the bottom of the bowl.
Step 6: Drying the Starch
Spread the collected starch onto a flat, clean surface. Allow it to air dry for about 24-48 hours, or until it becomes completely dry. Alternatively, you can use a dehydrator for quicker results.
Step 7: Storing the Cornstarch
Once dried, break it into small pieces and grind it again in a blender to achieve a fine powder. Store your homemade cornstarch in an airtight container in a cool, dry place.

What is the difference between corn flour and cornstarch?
Corn flour and cornstarch are both derived from corn, but they serve different purposes and have distinct textures. Corn flour is made by grinding whole corn kernels into a fine powder. It retains the bran and germ, resulting in a coarse texture and a slightly sweet flavor. This makes it suitable for baking, pancakes, and bread, where it contributes both flavor and nutrition.
On the other hand, cornstarch is made from the endosperm of the corn kernel, resulting in a much finer, powdery substance that is primarily used as a thickening agent in sauces, gravies, and puddings. Cornstarch is gluten-free and gives dishes a glossy finish. Understanding the difference is essential for choosing the right ingredient for your culinary needs.
Can I make corn flour and cornstarch at home?
Yes, you can make both corn flour and cornstarch at home using dried corn kernels. To make corn flour, you need to grind the dried corn kernels in a blender, food processor, or grain mill until they reach a fine, powdery consistency. It’s advisable to sieve the flour to achieve a uniform texture and remove any larger particles.
For cornstarch, the process is slightly different. You first need to wet the corn kernels and soak them overnight. After soaking, blend the corn with water, then strain the mixture through a fine mesh or cheesecloth to separate the liquid from the solid. Let the liquid sit to allow the starch to settle, and then pour off the water, leaving the starch behind. Once dried, you’ll have homemade cornstarch.
