This is a root vegetable used as a spice, to add wonderful heat to many dishes. Always try and get hold of a fresh root and don’t bother with the creamed jarred stuff. It is a large root and can be frozen whole and grated straight from the freezer. Horseradish is very popular in Eastern Europe, where it is paired with many vegetables and meats and often fresh and in large quantities. Combining fresh horseradish with creme fraiche becomes a tasty accompaniment to salmon, beef, pork, beetroot, mackerel or potatoes.
