Homemade prepared horseradish tastes fresher than store-bought varieties and is a surprisingly versatile condiment that will keep, refrigerated, for about three months. Start with fresh horseradish, which should be chilled to preserve its punch, and a box grater, a hand grinder or a food processor. Horseradish is potent, so make sure to keep the windows open or wear glasses to protect yourself from the fumes when handling the raw ingredient. Whisked into vinaigrettes, drizzled over poached fish or stirred into mayonnaise for a brighter egg salad sandwich, a spoonful of prepared horseradish wakes up whatever you're cooking.
- Serves: 4 persons
- 1pound fresh horseradish root
- ½cup white vinegar
- 1cup cold water, plus more as needed
- 1teaspoon kosher salt, or to taste
Step 1Peel the horseradish and cut out any dark veins. Open any nearby windows and use safety glasses to protect your eyes from strong fumes. Cut the horseradish into 3-inch segments. Pulse in a food processor equipped with a steel blade until finely chopped but not mushy. (Alternatively, grate the horseradish finely on a box grater.)
Step 2Transfer the horseradish to a quart-size jar. Add the vinegar and 1 cup cold water until horseradish is almost covered, adding more water if needed to cover. Stir in the salt, seal and refrigerate until serving. The prepared horseradish will last up to 3 months in the refrigerator.
