Yes, you should add salt to the water when boiling rice. Salting the water seasons the rice from the inside out, enhancing its flavor.
Adding salt to the water before you cook rice is a simple yet effective way to improve its taste. The rice absorbs the salted water as it cooks, resulting in a more flavorful final product. The salt doesn't just sit on the surface; it permeates each grain, seasoning it evenly. The amount of salt you add depends on your preference and the type of rice you're cooking. A general guideline is about 1/2 teaspoon of salt per cup of uncooked rice. For example, if you're cooking two cups of rice, use one teaspoon of salt. Adjust the amount to your liking after tasting the cooked rice. Remember that you can always add more salt later, but you can't take it away.
Use kosher salt or sea salt for a cleaner, less metallic taste compared to iodized table salt. Iodized salt can sometimes impart a slightly bitter flavor to the rice.
