This is becoming a habit â€“ a few weeks ago I wrote an entire column on the swede turnip, a humble inexpensive and ridiculously versatile Winter root. It got a tremendous response so this week Iâ€™m going to continue in the same vein and showcase Jerusalem artichokes. I know this is a vegetable that some may not have heard of but itâ€™s really worth seeking out, better still plant some in your own garden. Itâ€™s a kind of a miracle veg; you plant one this year there will be at least ten or twelve next year. They look like knobbly Â potatoes; they remain in the ground all winter and vary in colour from white to golden to purple.
Jerusalem artichokes are members of the sunflower family, Helianthus Tuberosus. Their US name is â€œsunchokeâ€. The foliage grows to a 2 metre and is often used as a hedge, windbreak or even a maze. It has a pretty yellow flowers in August brilliant for flower arrangements or scattered in a salad bowl.
But in this column we are concentrating on their culinary uses. Look out for them in greengrocers. We canâ€™t seem to find the name of the heirloom variety we have grown at Ballymaloe for over half a century, it has an excellent flavour, children love their uneven shapes they look like strange creatures so cause lots of amusement and curiosity. They love them roasted, crisp and golden at the edges or in their skins. Like the humble swedes I wrote about a few weeks ago they are super versatile. They make a silky puree alone or mixed with mashed potato or a sweet apple puree that pairs deliciously with all sorts of things, particularly pheasant or venison or use as a base of a vegetarian dish and top with rainbow chard stalks and leaves, and some chunks of sautÃ©ed mushrooms, crisp slivered garlic, a sprinkling of nutty Coolea farmhouse cheese. Â Despite their name, Jerusalem artichokes are not artichokes at all, Â neither do they come from Jerusalem, their curious nutty flavour is reminiscent of an artichoke heart which has a wonderful affinity with fish particularly mussels and scallops.
They also mix deliciously with other winter roots either in a medley of roast vegetables. Peeled and cut into chunks, mix them with carrots, parsnip, celeriac, turnipsâ€¦ Toss in extra virgin olive oilÂ or even more delicious some duck or goose fat left over from Christmas. They also absorb the gutsy flavour of herbs like Â Â rosemary and thyme, bay, sage and spices like cumin, coriander and garam masala. Iâ€™ve also included a recipe for Jerusalem artichoke soup â€“ easy peasy to make and everyone will love it, if you have pernickty eaters in your family who are put off by the sound of somethingÂ odd or unfamiliar â€“ just call it Winter vegetable soup and maybe up the quantity of the potato.
For a dinner party you can embellish it with chorizo crumbs (see my column of Saturday January 13th) Â or a few slices of scallop or a few fat mussels as a garnish.
Iâ€™m crazy about Hugh Maguireâ€™s smoked black pudding and found it pairs deliciously with slices of roast artichoke and some buttered leeks and a dice of sweet apple.
Just in case it comes as a surprise I should mention that they are hugely flatulent so very good for your gut biome. Peeling the older varieties can try your patience but the newer varieties are much smoother, I donâ€™t bother to peel them at all when freshly dug or whenÂ I decide to roast them, just cut lengthways or into thick rounds.
One other thing to know, Â like artichokesÂ and celeriac they oxidise quickly when peeled so pop them into a bowl of acidulated water (add a squeeze of lemon juice) until ready to cook.
Jerusalem Artichoke Soup with Avocado and Roast Hazelnut Salsa
Jerusalem artichokes were a sadly neglected winter vegetable, but many people have discovered them in recent years.Â We love the flavour and of course they are brilliantly nutritious â€“ packed with inulin. They look like knobbly potatoes and are a nuisance to peel, but if they are very fresh you can sometimes get away with just giving them a good scrub. Not only are they a smashing vegetable but they are also delicious in soups and gratins. They are a real gem from the gardeners point of view because the foliage grows into a hedge and provides shelter and cover for both compost heaps and pheasants!
50g (2oz) butter
560g (1 1/4 lb) onions, peeled and chopped
1.15kg (2 1/2 lbs) Jerusalem artichokes, scrubbed, peeled and chopped
salt and freshly ground pepper
1.1L (2 pints) light chicken stock
600ml (1 pint) creamy milk approx.
Avocado and Roast Hazelnut Salsa
1 ripe avocado, halved, stone removed, peeled and diced into neat scant 1 cm dice
3 tablespoons of hazelnuts, roasted, skinned and coarsely chopped
3 tablespoons of hazelnut or olive oil
1 tablespoon of chopped flat parsley
FlakyÂ sea salt and freshly ground black pepper
Melt the butter in a heavy bottomed saucepan, add the onions and artichokes. Season with salt and freshly ground pepper, cover and sweat gently for 10 minutes approx.Â Add the stock and cook until the vegetables are soft. Liquidise and return to the heat. Thin to the required flavour and consistency with creamy milk, and adjust the seasoning.
Serve in soup bowls or in a soup tureen. Garnish with avocado and roast hazelnut salsa.
To make the Salsa
Mix the ingredients for the avocado and hazelnut garnish. Taste and correct seasoning. This mixture will sit quite happily in your fridge for an hour as the oil coating the avocado will prevent it from discolouring.
Other good things to serve with Jerusalem Artichoke Soup
Chorizo Crumbs see my column on Saturday 13th January for the recipe
A few mussels or slices of scallop and a sprig of chervil, dice of smoked salmon and sprigs or flat parsley or chervil
Roast Jerusalem Artichokes
The winter vegetable is particularly good with goose, duck or pheasant. Here we half the tubers but they also work brilliantly cut into thick slices â€“ more delicious caramelized surface to enjoy
Serves 4 to 6
450g (1 lb) Jerusalem artichokes, well scrubbed.
2 tablespoons extra virgin olive oil

Cut the well-scrubbed artichokes in half lengthways. Toss them with the extra virgin olive oil and season well with salt. Transfer to a roasting tin and cook cut side down for 20â€“30 minutes, when golden, flip over and continue to cook for a further 5-10 minutes. Test with the tip of a knife â€“ they should be mostly tender but offer some resistance. Sprinkle with thyme or rosemary sprigs, season with pepper and serve.
Jerusalem Artichoke PurÃ©e with Chard, Garlic and Coolea Farmhouse Cheese
This smooth and creamy purÃ©e is excellent with pan-fried or grilled scallops.Â It can also be used with game such as venison, pheasants and wild duck.Â The trick to get a light and refined purÃ©e is to blend the vegetables while still hot.Â Keep some of the strained cooking water which may be added to the vegetables when blending.

Salad of Jerusalem Artichokes with Smoked Almonds and Preserved Lemon Dressing
Once can also use roast slices here instead of a raw artichoke.
4 good handfuls of perky bitter lettuce leaves
2 small Jerusalem artichokes, scrubbed clean
a little freshly squeezed lemon juice
110g (4oz) of smoked almonds, rough chopped *(see note at end of recipe)
sea salt and freshly ground black pepper
3 tablespoons (4 American tablespoons) extra virgin olive oil
1 tablespoon (1 American tablespoon + 1 teaspoon) white wine vinegar
2 teaspoons honey or agave syrup
a good pinch of sea salt
1/2 preserved lemon, seeds removed and finely chopped
Whisk all the ingredients for the dressing together, add the preserved lemon.
Wash and dry the salad leaves.
Next, use a mandolin to slice the artichokes paper thin â€“ otherwise slice with a very sharp knife.Â Squeeze a little lemon juice over the artichokes to prevent them from discolouring whilst also adding some flavour.
Put the salad leaves into a bowl, add the artichoke slices and roughly chopped almonds.Â Pour over enough of the dressing and toss to coat the leaves.Â Taste and correct seasoning with salt and pepper if necessary.Â Serve immediately.
To Smoke Almonds
We hot smoke a lot of different ingredients in a biscuit tin over a gas jet.Â Just scatter 2 heaped tablespoons of apple wood chips on the bottom of the tin.Â Put a rack on top.Â Place the almond on top of the wire rack.Â Pop on top of the gas on a high heat until the wood chips start to smoke and cover the box.Â Lower the heat and smoke for 4 minutes. Turn off the heat and continue to smoke for a further 1 minute.
Braised Jerusalem Artichokes
The most basic and delicious way to cook artichokes. Serve with pheasant, chicken, pork, lambâ€¦
675g (1Â½ lbs) Jerusalem artichokes
25g (1 oz) butter
1 dessertspoon water
salt and freshly-ground pepper
Peel the artichokes thinly and slice 1/4 inch (5mm) thick.Â Melt the butter in a cast-iron casserole, toss the artichokes and season with salt and freshly-ground pepper.Â Add water and cover with a paper lid (to keep in the steam) and the saucepan lid.Â Cook on a low heat or put in a moderate oven, 180Â°C/350Â°F/regulo 4, until the artichokes are soft but still keep their shape, 15-20 minutes approx.Â (Toss every now and then during cooking.)
Serve sprinkled with chopped parsley.
* If cooking on the stove top rather than the oven turn off the heat after 10 minutes approx. – the artichokes will continue to cook in the heat & will hold their shape.
