Q: I love horseradish but even a small jar loses it’s potency before I’m able to finish it. Any ideas to prolong the life of bottled horseradish? Alternatively, if I buy fresh horseradish root, how should I store it and how long will it remain fresh and potent?

A: Whether fresh or jarred, horseradish will start to lose its pungency once grated or cut.

Obviously, keeping the jar in the refrigerator will help to keep it fresh and strong, as will the vinegar in which it is packed. You also can store the jar in the freezer.

Depending on the conditions in your refrigerator, fresh horseradish root will keep for a week or more in the vegetable bin. Once cut, however, its pungency will begin to lessen.

For longer storage, consider grating it and freezing it in small amounts in ice cube trays they way you might freeze herbs. When frozen, you can place the cubes in a zipper-lock freezer bag and just take it out in small amounts to use it.
