Most people don't realize you can make your own horseradish in the comfort of your own kitchen. This recipe shows you just how. Warning! You may want to wear a mask when preparing to protect your eyes from the strong aroma.
Shred horseradish on food processor grater. Then shred beets (directly on top horseradish). Remove food from processor. Remove grater attachment and attach blade. Dump grated horseradish and beets in and process, adding vinegar, salt and sugar midway, to make a pasty sauce. Stop machine, taste some horseradish on cracker. Adjust seasonings and process to combine. Let stand and chill before serving. Flavor will mellow as horseradish matures.
