Can you use plain flour instead of cornflour?

You can sometimes use plain flour instead of cornflour, but it depends on the recipe and the desired outcome. Here's a breakdown:

When you CAN use plain flour instead of cornflour:

* Thickening sauces: Plain flour can thicken sauces, but it won't be as smooth or as shiny as cornflour. It will also have a slightly different taste.

* Baking: Plain flour can be used in some baking recipes that call for cornflour, but you may need to adjust the recipe slightly. For example, you may need to add more liquid or reduce the baking time.

* Coating foods: Plain flour can be used to coat foods before frying, but it won't be as crispy as cornflour.

When you SHOULD NOT use plain flour instead of cornflour:

* For a smooth, glossy finish: Cornflour is known for its ability to create a smooth and glossy finish in sauces and gravies. Plain flour will not achieve the same result.

* For a light and airy texture: Cornflour is often used in recipes where a light and airy texture is desired, such as in cakes and pastries. Plain flour will not provide the same level of lightness.

* For a crisp coating: Cornflour creates a very crisp coating when used for frying. Plain flour will not be as crisp.

In general, it's best to stick with the original recipe unless you are confident in your ability to make adjustments. If you're unsure, it's always best to err on the side of caution and use the specified ingredient.

Alternatives to cornflour:

* Potato starch: Provides a similar smooth, glossy finish to cornflour and is often used in Asian cooking.

* Rice flour: Adds a slight nutty flavor and can be used in some thickening and baking applications.

* Tapioca flour: Creates a very clear and glossy finish in sauces and can be used in some gluten-free baking.

Ultimately, the best substitute for cornflour will depend on the specific recipe and your desired outcome.
