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?adcelannotate = {"mobilepaywallcategory" : "MOBILE_PREM-FOOD","nativepaywallcategory" : "NATIVE_PREM-FOOD"};
