Salt-free methods refer to cooking techniques that enhance flavor without the use of salt. These methods often involve using herbs, spices, citrus, and other natural ingredients to create depth and complexity in dishes. For example, garlic, onions, and pepper can add significant flavor without the need for added sodium. Another approach is to focus on the natural flavors of fresh ingredients. Techniques like roasting or grilling can intensify the taste of vegetables and proteins, making them more enjoyable. Additionally, using vinegars or broths can provide a savory element that compensates for the absence of salt in meals.
