100% Pure Horseradish Root: Sourced from the finest horseradish roots for a natural and potent flavor. Our extra hot horseradish is prepared fresh, ensuring a strong, vibrant taste in every spoonful. **EXTRA HOT!!** Note- Horseradish, especially the prepared jarred kind, should always be refrigerated before opening and kept refrigerated after opening to maintain its flavor and potency as it loses its pungency quickly when exposed to air. All prepared horseradish has to be refrigerated.
