Can Use plain flour substitute corn flour?

No, you can't directly substitute plain flour with corn flour. Here's why:

* Gluten Content: Plain flour is a wheat flour with gluten, giving it elasticity and the ability to create structure in baked goods. Corn flour is gluten-free and has a much finer texture.

* Texture: Corn flour absorbs more liquid and creates a denser, crumblier texture than plain flour. This is why it's often used for making cornbread or thickening sauces.

* Flavor: Corn flour has a slightly sweet, corn-like flavor, while plain flour has a neutral flavor.

When can you substitute plain flour?

* For thickening: Corn flour is a good thickener for sauces and soups. Just be sure to use less than you would plain flour, as it absorbs more liquid.

* For a crumbly texture: If you want a crumbly texture, you can use corn flour in combination with other flours, like in cornbread or cakes.

Alternatives to plain flour:

* All-purpose flour: A good general substitute for plain flour in most recipes.

* Self-rising flour: Can be used in place of plain flour, but you may need to adjust the amount of leavening agents in the recipe.

* Gluten-free flour blend: A good option if you are avoiding gluten.

Remember: It's always best to consult the recipe you're using for specific substitution recommendations.
