Corn flour, often referred to as cornstarch in some regions, is a fine, white powder derived from corn kernels. Unlike cornmeal, which is coarser, corn flour is finely ground to a powder and has a smooth, silky texture. It’s widely used in cooking, baking, and food processing for its ability to thicken liquids and create a delicate, light texture in a variety of dishes.

Key Features:
Fine Texture: Corn flour is finely ground, resulting in a powdery, smooth texture, ideal for creating light and airy baked goods or as a thickening agent for sauces and soups.
Gluten-Free: Naturally gluten-free, corn flour is an excellent choice for those who are sensitive to gluten or following a gluten-free diet.
Neutral Flavor: With a subtle, neutral taste, corn flour doesn’t overpower other flavors in your dishes, making it versatile in both sweet and savory applications.
Culinary Uses:
Baking: In baking, corn flour is often used to add lightness to cakes, cookies, and biscuits. It helps to produce a finer crumb texture, especially when used alongside wheat flour.
Coating for Frying: Corn flour is commonly used as a coating for fried foods like chicken, vegetables, or tempura. It creates a crisp, light outer layer when deep-fried or pan-fried.
Health Benefits:
Gluten-Free: Corn flour is an excellent substitute for wheat flour in gluten-free cooking, making it suitable for people with celiac disease or gluten sensitivity.
Nutritional: Corn flour is rich in calories due to its carbohydrate content, making it a good source of energy.
Health Considerations:
Moderation: While corn flour is gluten-free, it is highly processed and lacks the nutritional content of whole grains. As it is rich in carbohydrates, excessive consumption can contribute to weight gain or blood sugar spikes, especially for people with diabetes.
Storage: Corn Flour should be stored in a cool, dry place in an airtight container to prevent it from absorbing moisture or becoming contaminated.
