Uses of Horseradish

With medicinal and nutritional values, horseradish has a variety of uses.

The tangy taste of this root vegetable comes from a compound called allyl isothiocyanate. Horseradish is used in many different ways when it comes to cooking. One of its primary uses is making flavoured vinegar, which can help preserve it for months.

Another known use of it is in the vegetable leaves, making many salad recipes enjoyable. It also serves an ingredient in dishes such as meat, fish, sandwiches, sauces, and even cocktails.
