When to Use Flour?

For example, for 2 tablespoons of flour, you'd use 1 tablespoon of cornstarch. If, by chance, your sauce has an acidic or vinegar taste, it's best to use flour to tone down the acid. Flour also works best if your sauce is based with a fat; if your recipe calls for butter to start with, use flour to thicken.

When should you not use flour?

Flour has a long shelf life but generally goes bad after 3–8 months. White flour may last longest due to its lower fat content, while whole-wheat and gluten-free varieties spoil sooner. You can extend flour's shelf life by sealing it properly or refrigerating or freezing it.

For what purpose flour is used?

As the name suggests, all-purpose flour is suitable for all types of baked goods such as bread, biscuits, pizza, cookies, muffins, etc. It is also used in thickening gravies and sauces. Due to bran removal and loss of nutrients, all purpose flour is usually enriched with vitamins and minerals.
