How to Make Homemade Horseradish
- Pick a horseradish that is firm, with no mold or green spots and free from cuts.
- Peel off the brown skin and cut off the ends (tough); cut into cubes. Measure the amount of horseradish so you have the right quantity of vinegar.
- Transfer the cubes in a bowl of a food processor and pulse until well minced. If you are processing on the stove or counter top, start the fan or open a window as your eyes might start burning (you might want to wear googles or glasses).
- After processing, if you want a "hot" horseradish, wait about 5 minutes before adding vinegar otherwise pour it right away. Then add salt and pulse to blend until very smooth. Scrape the sides of the bowl and spoon into an airtight container before transferring it to the refrigerator.
