Wash the horseradish after buying it from the market. After that, peel the skin off and remove the tasteless core of the herb full of fiber.
Next, cut the horseradish into small pieces.
After that, sprinkle a tiny amount of lemon juice and vinegar mixed with water all over the pieces of horseradish.
Please put it in a food processor. If the mixture comes out too liquidy, then you need to drain the excess amount of water.
Store the grated horseradish in a jar. Use a rubber spatula to transfer the mixture to a jar from the processor.
