It’s the inspiration for Velcro, an Asian super ingredient, and it grows abundantly in Winnipeg. Burdock is this month’s featured Fantastic Foraged Fare.
While the leaves, stems, and even seeds of the burdock both have their culinary uses, it’s the taproot of young burdock plants that interest the forager.
Harvested and eaten as a root vegetable, burdock root is a surprisingly common ingredient in Asian cooking, occurring candied in stirfries, pickled as a side or served julienned in a salad.
Burdock root takes well to braising, maintaining its al dente character where carrots, parsnips, and other root veggies have long since turned to mush.
Flavour-wise, burdock root has a sweet, mild taste but a residual bitterness due to pronounced tannin content. This can be mitigated by soaking sliced root in water for five to ten minutes.
Due to its tenacious tap root, which can grow up to 1 metre long and 2 cm wide, it’s tough to harvest and retains a lot of soil. Scrubbing the outside can extract much of the detritus, but your best bet is peeling.
Like apples or avocado, it will discolour as a result of oxidization, so a quick bath in ascorbic acid (any vitamin C rich liquid like orange, lemon, lime juice) or acidulated water (white vinegar works) can inhibit this enzymatic action.
Immature flower stalks may be harvested in late spring, before flowers appear; their taste resembles that of artichoke, a relative of burdock. Beyond this, the flowers will turn to the all too familiar burrs which cling to clothing and inspired George de Mestral, the inventor of velcro, over 60 years ago.
Once peeled, stalks can be eaten raw, or boiled in salt water. The Japanese eat the young leaves, harvested while they are still soft in the early spring.
Nutritionally speaking, Burdock Root contains a fair amount of dietary fibre, calcium, potassium, and the polyphenol oxidase (which causes its discolouration by forming bitter tannin-iron complexes). This happens to work very well with pork and miso soup.
Beer knurds take note: Europeans exploited this inherent bitterness in beer before the widespread adoption of hops, and dandelion and burdock syrup, which traces its origins back to the medieval period, remains a popular soft drink in the United Kingdom.
Medicinally, burdock has been employed as a remedy for measles, arthritis, tonsillitis, colds, and throat pain. It’s also a diuretic, which enhances the performance of many of the organs which purify the body and eliminate toxins or waste.
