Salt in Indian spice mixes acts as a flavor enhancer, preservative, and binding agent, balancing the other spices and extending the shelf life of the blend.
Salt plays a multifaceted role in Indian spice mixes, going beyond simply adding a salty taste. Firstly, it acts as a flavor enhancer. Salt has the ability to bring out the inherent flavors of other spices, making them more pronounced and vibrant. It balances the sweet, sour, bitter, and umami notes, creating a harmonious blend.
Secondly, salt acts as a preservative. By drawing moisture away from the spices, it inhibits the growth of mold and bacteria, thereby extending the shelf life of the spice mix. This is particularly important in humid climates where spices are more susceptible to spoilage.
Finally, salt can act as a binding agent. In some spice mixes, particularly those that are ground coarsely, salt helps to bind the different spices together, preventing them from separating and ensuring a more consistent flavor profile throughout the blend. The amount of salt used varies depending on the specific spice mix and its intended use.
When making your own spice mixes, use a good quality sea salt or Himalayan pink salt. Avoid iodized table salt, as the iodine can sometimes impart a metallic taste to the blend.
