The roots were dug completely from the plant, which is a perennial, only the side roots were utilized. The roots were washed and lightly scraped, then cut in small pieces and put in the blender with sufficient vinegar to make a smooth paste. It is important to complete the process relatively soon after picking the roots, since they get woody if allowed to dry too much.
The odour is mouth-watering, and the fumes make the eyes water. Nothing attacks the mixture in the jar, kept in the refrigerator. I have kept similar for over a year and it is still high quality.
Two strong side roots were planted in pots for next year's plants. I treat the plant as an annual since the roots can be tough off the perennial, and the plant grows sufficiently in Zone 5 for good quality condiment. Apparently the plant can be invasive if the climate is ideal. Durgan.
