Horseradish and Wasabi

Horseradish has a hot and piquant flavor, reminding of strong mustard, mainly used in sauces –in Western cooking, more precisely, North European cooking- for roast beef, chicken or fish; an ingredient for dips and served with vegetables such as beets or cabbage.

Wasabi –the Japanese horseradish- is used –in Japanese cooking, of course- to make a dip, more of a paste, for fish. Try wasabi paste along sushi, quite flavorful.

Curious Facts about horseradish

Horseradish was widely used in the Middle Ages to treat a variety of complaints ranging from digestive problems, to gout, swellings and arthritis. It became a popular flavoring in Northern Europe where it was used very much like mustard to accompany oily fish. It has been used to spice pickles and ketchups and its role as traditional garnish for roast beef is relatively recent. Horseradish is one of the five bitter herbs used in the Jewish Passover.

The leaves can be used in salads, but it is the large white root what the part employed the most.

The Japanese horseradish, also known as wasabi, is a completely different species. An imitation wasabi is prepared using horseradish, mustard seed and green food coloring.

How to Identify horseradish

The horseradish plant is an herbaceous-perennial with long spiky leaves and large white roots. Occasionally tiny white flowers come out during the summer. The roots are long, fleshy and white in color; they only liberate their piercing aroma when cracked.

How to use and store horseradish

Fresh horseradish ban be found in many supermarkets. The roots are also available dried, in flakes or ground, or in commercial sauces. Typical horseradish sauce is the grated root mixed with cream. Horseradish vinegar is the root combined with shallots, onions, garlic, and red pepper in vinegar.

Fresh horseradish root should be refrigerated and peeled, or scrubbed thoroughly, before using it. Grate the flesh, discarding the tough inner core. Grated root quickly looses aroma, but it freezes well or it can be preserved in vinegar.

Powdered horseradish has to be reconstituted before using it. It is made by grinding the root and drying in a gentle heat.

How to grow horseradish

The plant propagates from root cuttings. Plant in late winter, removing all side shoots, in holes about 1 ft (32 cm) deep. Keep holes 18-20 in ( 45-50 cm) apart. Choose moist soil and a summy spot.

Keep the plant isolated and remove all trace of roots when digging it up, otherwise it will grow like weed and invade the garden.
