The Jerusalem artichoke is often overlooked at the vegetable shop because of its un-uniform knobbly shape.
It also suffers from another problem: not a lot of people know what it tastes like or what on earth to do with it.
However, if you get past that lumpy exterior you will be treated to one of winter’s most fabulous tubers.
It has an earthy, sweet and almost nutty flavour which really helps bring out the flavour of fish.
When you are buying look for firm, unwrinkled roots, but don’t worry about how knobbly they are – their strange appearance doesn’t affect the taste at all.
This vegetable can be treated like a potato with the skin on, but should be thoroughly scrubbed before cooking or peeled to reveal its creamy interior.
I prefer to peel it mainly because the skins tend to discolour the end result.
It can therefore be roasted, boiled, fried and I have even eaten raw Jerusalem artichokes sliced very finely with extra virgin olive oil and a few anchovies. This made a delicious starter.
Most people will turn the tuber into a comforting soup but it makes a wonderful smooth purée which matches white fish perfectly. Here we top the fish with breadcrumbs and roasted hazelnuts to help with the nuttiness and give extra texture.
