Yes, besan (gram flour) can be mixed with other flours and stored safely in an airtight container in a cool, dry place, away from direct sunlight. This mixture typically lasts as long as the flour with the shortest shelf life.
Detailed Explanation:
Besan, also known as gram flour or chickpea flour, is generally safe to mix with other flours like wheat flour (atta), rice flour, or even gluten-free flour blends. The key to safe storage lies in preventing moisture absorption and pest infestation. Here's a breakdown:
- Mixing: Ensure both the besan and the other flour are dry and free from any contaminants before mixing. Use a clean, dry utensil to combine them thoroughly. The ratio depends on your recipe, but it's perfectly acceptable to blend them.
- Container: The most important factor is the storage container. Use an airtight container made of glass, plastic, or metal. Make sure the container is clean and completely dry before adding the flour mixture.
- Storage Location: Store the container in a cool, dry, and dark place. Avoid areas near the stove, sink, or any place where temperature and humidity fluctuate. A pantry or a cool cupboard is ideal.
- Shelf Life: The shelf life of the mixture will be determined by the flour with the shortest expiration date. Check the expiration dates of both the besan and the other flour before mixing. Generally, properly stored flour mixtures can last for several months.
- Checking for Spoilage: Before using the flour mixture, always check for signs of spoilage, such as a musty odor, discoloration, or the presence of insects. If you notice any of these signs, discard the mixture.
Pro Tip:
To extend the shelf life and prevent insect infestation, consider adding a bay leaf to the storage container. The aroma of the bay leaf naturally repels many common pantry pests.
