The kick of horseradish

I caught a snippet of The One Show last night and was fascinated to find out about Mapson’s Farm who grow fields and fields of horseradish. I don’t grow fields and fields of horseradish but I do have quite a big patch and as the feature made me realise I haven’t harvested any yet this season. Like parsnip horseradish improves with the onset of winter and hard frost but the danger is that procrastination can end up with no horseradish – just when you decide to dig it up there peeping through the soil is the first sign of the new season’s growth.

I would love to think that the plant got its name from looking like a giant radish that has a pungent flavour that gives a ‘kick’ to food. However it is more likely that the name comes from the prefix horse meaning large and it is a large root. Horseradish (Cochlearia armoracia or Armoracia rusticana) has been cultivated since the earliest times and has many medicinal as well as culinary uses. The young leaves can be used in salads but it is the knobbly root that is most commonly used.

Horseradish is always grown from root cuttings and in fact when you dig up the root to harvest it is virtually impossible to dig it all up so be warned if you introduce horseradish to your garden plant it somewhere where you don’t mind it taking up a fairly permanent residence.

I think it is sad that most people’s encounter with horseradish is via a jar of commercially produced horseradish sauce as it is a wonderfully pungent and versatile herb. But it’s not for the faint hearted – peeling and grating the root can bring a tear to the eye of just about everyone and it’s pretty good at clearing the sinuses too! My solution is to dig up the roots once a year and prepare myself for a few tears.

One of the simplest things and most useful things to make is horseradish butter – simply peel the root and either grate it or using a food processor mix it into butter. Pat the butter into a narrow sausage shape and wrap it in foil (or the butter wrapper) and then pop it in a bag and freeze. The butter can be used straight from the frozen block whenever you want it – cutting a few slices and returning the rest to the freezer for use another day. Horseradish butter is a wonderful addition to mashed or boiled root vegetables especially carrots and parsnips, melted into mashed potatoes or even topping a succulent piece of beef, chicken or fish.

Horseradish loses its flavour if it dries out so if you don’t use all your harvest in one go either store the complete roots in damp sand in a cool place or peel and store the root immersed in white wine vinegar. Then grate a little whenever needed. I usually resort to the sand method and then I don’t use it all by late spring I can pop it a pot to grow and give to friend or even sell for charity.

Horseradish helps with the digestion of rich and oily food so that’s why horseradish sauce is the traditional accompaniment to roast beef. It’s quick and easy to make by adding the finely grated root to whipped cream and adding a dash of white vinegar and even a little dry mustard if you fancy it But one of my favourite uses is as the ‘secret’ ingredient in smoked mackerel pate to give it a bit of a kick.

So thanks to the timely reminder on The One Show the job of digging up and ‘processing’ the horseradish has moved up the ‘to do’ list and I look forward to horseradish butter and mackerel pate even if the tears will flow in the process. Maybe this year I will remember to try the leaves when they are young and tender too.
