The term 'Salsa Quality' is composed of four words: TANG, ZEST, HOTNESS, and Ernst. TANG is a sharp, acidic flavor that is often associated with citrus fruits. ZEST is the outermost layer of a citrus fruit's skin, which contains essential oils and flavor compounds. HOTNESS refers to the spiciness of a salsa, which can range from mild to very hot. Finally, Ernst is a German word meaning 'SERIOUSNESS' or 'EARNESTNESS, ' which can be used to describe the overall quality of a salsa. Together, these four words describe the flavor, texture, and intensity of a salsa, making it an important factor in determining its overall quality.
