3. Texture: Corn starch has a fine, powdery texture, while flour has a more granular texture.
4. Flavor: Corn starch has a neutral flavor, while flour can impart a slightly nutty flavor.
5. Thickening Strength: Corn starch is a stronger thickening agent than flour. It requires less to achieve the same level of thickening.
6. Clarity: Corn starch produces a clear gel, while flour can produce a cloudy gel.
7. Heat Tolerance: Corn starch is more heat-resistant than flour. It can withstand higher temperatures without losing its thickening properties.
When to Use Corn Starch vs. Flour

2. Cook Thoroughly: Corn starch and flour need to be cooked thoroughly to activate their thickening properties. Bring the mixture to a boil and simmer for at least 1 minute.
3. Do Not Overheat: Overheating corn starch or flour can cause it to lose its thickening power.
