Ingredients

One of the best things about this horseradish sauce, is how simple it is.

• Prepared horseradish – available in mild, hot or extra hot. This gives a mild heat and makes this sauce come alive!
• Mustard – Dijon is best, but regular yellow mustard also works
• Sour cream – is creamy and sour, adding depth and texture
• Mayonnaise – the vinegar and creamy nature provide structure and extra creaminess
• Salt – brings the flavors together

What is horseradish?

It is a root that belongs to the Brassica family, along with broccoli, cabbage and mustard. It doesn’t give off any scent until it’s cut. Once it's sliced into, it releases its peppery, zesty scent.

It can be used by itself as a condiment and is most often used as an ingredient in many dips and sauces.

If you follow a low-FODMAP diet, horseradish is one of the best low-FODMAP seasonings to add heat to a dish because it doesn't contain capsaicin found in chili peppers. However, it can potentially aggravate IBS symptoms if it's consumed in large amounts.

Some people confuse it with wasabi root, which is also from the Brassica family. While it is a spicy root, similar to horseradish, wasabi root has a slightly different flavor and is a lovely green, where horseradish is white.

What is prepared horseradish?

It is grated horseradish combined with vinegar and other natural preservatives, such as citric acid. Vinegar is used to stabilize the flavor and heat. You can find it in the refrigerated section of the grocery store.

Prepared horseradish differs from horseradish sauce. The prepared version has minimal ingredients to preserve the grated root, where the shelf-stable sauce often contains other additives and preservatives and is meant to be served as a stand-alone condiment. Prepared horseradish is intended to be an addition to recipes, as opposed to being a condiment by itself.

Instructions

All you need is a bowl and a whisk or spoon to bring this simple recipe together.

Add all ingredients to a medium-sized bowl.

Stir or whisk until smooth and creamy.

TIP: As it chills, the flavors blend and can intensify, so it’s even better as a make-ahead condiment. It’s best to make it an hour before serving, but isn’t necessary.

How to serve
