Tasteless (unrefined) refers to substances that have not undergone processing to enhance flavor or remove impurities. This term is often used in the context of food products, such as oils or sugars, that retain their natural characteristics without additives. Unrefined products are typically considered healthier because they maintain more nutrients and natural flavors. In culinary contexts, tasteless unrefined ingredients can include items like unrefined sugar or cold-pressed oils. These ingredients may have a more subtle taste compared to their refined counterparts, making them suitable for recipes where a delicate flavor profile is desired.
