Yes, ginger masala can be stored in layered oil jars. The oil acts as a preservative, preventing spoilage and extending its shelf life.
Storing ginger masala in layered oil jars is a traditional method of preservation. The oil creates an anaerobic environment, which inhibits the growth of mold and bacteria that cause spoilage. Here's how it works:
Preparation: Ensure your ginger masala is properly prepared and cooked. This usually involves grinding ginger with spices and cooking it in oil until the moisture evaporates.
Sterilization: Sterilize the glass jar you plan to use. This can be done by boiling it in water for about 10 minutes.
Layering: Once the jar is cooled and dried, start layering the ginger masala. Add a layer of masala, then pour a thin layer of oil over it, ensuring the masala is completely submerged. Repeat this process until the jar is full, ending with a generous layer of oil on top.
Storage: Store the jar in a cool, dark place. Refrigeration is optional but can further extend the shelf life.
The oil used should be a neutral-flavored oil like vegetable oil, sunflower oil, or groundnut oil. Mustard oil is also commonly used in some regions for its preservative properties and distinct flavor.
Always use a clean, dry spoon when taking out the ginger masala from the jar. Introducing moisture or contaminants can lead to spoilage, even with the oil preservation method.
