There have been quite a few recipes for kohlrabi in the press recently – prescient of the awakening of spring.
But it’s not always that easy to find in non-german speaking countries, or outside Kashmir where they eat a lot of it. So what is it and what constitutes a reasonable substitute if you can’t find it?
The name of this vegetable, kohlrabi is derived from two german-rooted [sic] words – Köhl which means cabbage as in Chancellor Köhl (can you imagine a Prime Minister Cabbage in the UK?… lovely thought…); and rabi which means turnip in the Swiss German (in Swiss French it’s almost the same – ravi). The rabi bit arises because the swollen stem of the kohlrabi looks a bit like a turnip…and also possibly because it has a sharp mustardy taste a bit like a summer baby turnip. It has a grainy texture, a bit like the stem of broccoli.
You can use both the stem and the root in cooking. Young kohlrabi are crisp and juicy – fleshier, sweeter and milder than the heart of a cabbage, but still retaining a sharpness. The scientific name for kohlrabi is brassica oleracea.
In terms of substitutes you can use spring greens, kale or cavolo nero instead of the leaves. For the swollen stem you could use turnips, radishes, the stems of broccoli (not surprising as the kolhrabi is itself a stem), or possibly some celeriac with a little added mustard.
How to use kohlrabi
You can use kohlrabi in both cold and hot dishes. Buy more than it looks as if you need. You will have to peel off both layers of skin and what you have left at the end of this process is a lot smaller than what you started with.
