A few days ago, my wife entered a greengrocer’s to get some fruit and came out with fruit but also with a gleam in her eye. “I have bought some Jerusalem artichokes”, she announced, and I was delighted to hear it.
It was a University flatmate who many, many (many …) years ago introduced us to this tuber. One evening, it must have been about this time of the year, he appeared in the kitchen with these strange-looking things.
As we looked at them curiously, he asked us if we had ever tried them. When we confessed that we had not, he promised us a plateful. He was as good as his word. I cannot remember now how he cooked them – more on this later – but it allowed us to appreciate that delicate artichoke taste which is the hallmark of this tuber.
Its name in English recognizes this gustatory affinity to the artichoke. And it is that artichoke taste which drew me to this lumpy, knobbly little tuber; as I have written in a previous post, I am very partial to artichokes.
Not that we’ve eaten Jerusalem artichokes all that often since that first tasting 40-plus years ago. It is one of the few foodstuffs that is still only found seasonally – it’s available from late Autumn to late Winter, and very difficult to keep once out of the earth – so unless you maintain a sharp lookout, you’re liable to miss it. Because of that, and because, frankly, of a bad press – it has a reputation of being something you feed to animals and only eat if you’re literally starving – it’s not grown in large quantities and supermarkets rarely stock it. Once, I bought a whole load of ginger because I thought they were Jerusalem artichokes. They really do look quite similar, as I think this photo shows; the resemblance between the two has often been noted.
I cannot remember where it was that I bought this ginger, but it must have been somewhere where I couldn’t read the labels – Thailand, maybe? I also cannot remember what we did with all the ginger: probably, after a few half-hearted attempts to drink tea with a lot of ginger in it, we threw it away.
I must confess to also rather liking the name, which I find satisfyingly quirky. I initially thought that the “Jerusalem” part of the name indicated a Levantine origin for the tuber; maybe, I romantically mused, it was a foodstuff brought to Europe by returning Crusaders. But no, I discovered, North America is its place of origin. It is actually the tuber to a rather lovely flower, the Helianthus tuberosus.
It is part of the Great Columbian Exchange, that massive intercontinental move of plants and animals (and diseases … and people) which took place after we Europeans discovered the Americas: plants and animals mostly travelling from the Americas to Europe and the rest of the world, and vice versa for diseases and people. I’ve written an earlier post about a minor representative of this exchange, the prickly pear. The Jerusalem artichoke is another minor representative. It is the relative of a much more important representative, also an emigrant from North America, the common sunflower, planted in vast quantities for its oil-bearing seeds.
The French explorers of North America seem to have been the first Europeans to report on this tuber, and French colonists the first to send exemplars back to Europe. Samuel de Champlain, the explorer of the Saint Lawrence River and the Great Lakes, first came across it on Cape Cod. As related on the US National Park Service website, “after rounding the headlands of Cape Cod in 1605, the French explorers sailed south along the ocean side of the outer Cape. Avoiding shoals and sandbanks, they managed to enter the first embayment they encountered. They called the place Malle Barre and left the ship to go onshore to inspect the Native American settlement. Champlain described the scene:
Before reaching their wigwams we entered a field planted with Indian corn … The corn was in flower and some five and a half feet in height. There was some less advanced, which they sow later. We saw an abundance of Brazilian beans, many edible squashes of various sizes, tobacco, and roots which they cultivate, the latter having the taste of artichoke. The woods are full of oaks, nut-trees, and very fine cypresses, which are of reddish colour and have a very pleasant smell. There were also several fields not cultivated, for the reason that the Indians let them lie fallow … Their wigwams are round, and covered with heavy thatch made of reeds. In the middle of the roof is an opening, about a foot and a half wide, through which issues the smoke of their fire.”
Champlain helpfully included a map of the embayment in his printed report.
Another Frenchman, Marc Lescarbot, met Champlain soon after this in Port-Royal, a new settlement on the coast of what is now Nova Scotia. I throw in here a map of Port-Royal which Lescarbot included in the book he wrote some years later.
Among other things, Champlain introduced him to the tuber. Lescarbot described it as follows: “a sort of root, as big as a beet or truffle, tasting rather like chard but more agreeable”. Chard is a vegetable which I’m fond of, fond enough to have written a post about it a little while back. Lescarbot was onto something, I think: the two share a similarly delicate taste. Nevertheless, in the end I would plump for the artichoke connection, so Jerusalem artichoke it should be, not Jerusalem chard.
Europeans were responsible for the global redistribution of the Jerusalem artichoke, but in truth humans had already started to move the plant out of its natural range before Europeans discovered the Americas. When Champlain, Lescarbot, and all the other anonymous European colonists came across the native plantations of the Jerusalem artichoke on the East coast, it looked to them like the plant had always been there. But actually that was not so. The plant’s natural range is somewhere in central North America, straddling the modern US-Canada border. However, the American Indians, recognizing the tuber’s value as a foodstuff, and especially its availability during the winter months when other food is often scarce, had centuries earlier carried it out of its natural range, all the way to the east and west coasts of North America, and down south into Mexico too.
Fascinating stuff, but none of it explains that “Jerusalem” bit of the name. Unfortunately, the chroniclers of the 17th century – the time when the Jerusalem artichoke arrived in Europe and was diffusing across the Continent – were more interested in the Great Men (and possibly Great Women) as well as the Great Events of their time rather than in the names being given to new vegetables. So it has been left to modern historians and etymologists to make some educated guesses. I give two of these guesses here, the two that seem to me the most likely – or perhaps the least unlikely. The first guess has it that the tuber made its way to Rome, as a foodstuff which had miraculously saved the French (Catholic) colonists of North America from starvation. It was planted in the Vatican gardens, whose gardeners gave the plant the name girasole articiocco – “girasole” being the Italian name for the sunflower (readers will recall that the plant is a cousin to the sunflower). The usual mangling of foreign words in British mouths meant that girasole articiocco became Jerusalem artichoke. This is quite neat and is the guess I would normally lay my money on, but I can’t explain to myself how Protestant Britain would have picked up a name being bandied about in the Catholic Vatican. The second guess has it that the tuber originally entered the UK from the Netherlands and more specifically from the town of Terneuzen (the Dutch botanist Petrus Hondius, who lived there, reported in the early 1600s on having successfully planted a shriveled tuber which he had received, no doubt from Dutch colonists in North America). In British mouths, Terneuzen artisjokken got mangled into Jerusalem artichokes. Trade between the two countries was brisk, so a transfer such as this of a new foodstuff sounds quite reasonable to me. But a mangling of Terneuzen into Jerusalem seems a bit of a stretch.
One of the rare places where my wife and I came across the Jerusalem artichoke was in Paris. The French name for the tuber is equally quirky: topinambour. Here again the mists of time have veiled over the origin of the name. The best guess is that the tuber began to appear on Parisian plates at around the time that a delegation of three Amerindians from the Tupinambá tribe, which had settled on the Brazilian coastline, were paraded before King Louis XIII and his court in the Tuileries (three others had died en route). They were sent there by some missionaries, who were competing with the Portuguese for the souls of the local “savages”. No doubt the idea was to get the king interested in defending French interests in Brazil. I’m not sure they succeeded in that, but the Tupinambá created a sensation. One of the missionaries commented enthusiastically: “Who would have thought that Paris, used to the strange and the exotic, would go so wild over these Indians?”. After being paraded before the king and his court, no doubt in their “savage” state, the three Tupinambá were taken off to a church, baptized, and dressed in more “civilized” garb.
Parisians, being vague about the geography of this New World that was being discovered before their very eyes but knowing that the tuber came from somewhere over there, simply decided that the Topinambá had brought the tuber with them and began to call it the topinambour.
Helianthus tuberosus grows extremely well in Europe, it is very easy to grow, and as I said earlier its tuber is available in the winter months when other foods can be scarce. As a result, the plant’s popularity grew, especially in France, where it saw its heyday in the 18th Century. Not only were people eating it, but it was given as feed to livestock. It was so widespread in France that one of the days in the Revolutionary calendar – the thirteenth day in the month of Brumaire, to be precise – was dedicated to it. But by then, its days were numbered. The potato (another representative of the Great Columbian Exchange), after facing a century or so of hostility in France, finally won wide acceptance. It eventually completely eclipsed the topinambour.
Which is sad really, because the Jerusalem artichoke/topinambour is really quite good to eat. I personally prefer the tubers steamed (they can be boiled, too, but they risk crumbling in the water).
There’s Jerusalem artichoke soup, too, which I have yet to try.
Then they can be roasted
or prepared in just about any other way one can think of – there are recipes out there for all tastes.
I feel that I cannot in all fairness finish this post without mentioning one negative thing about the Jerusalem artichoke: the plant has a tendency to be invasive, a problem I’ve written about several times. It’s the tubers – if you leave just one little piece in the ground, they will proliferate. This is fine if you have them planted in your garden or in a field; it means you don’t have a problem getting another harvest next year. But it is not fine if the tuber somehow jumps the garden fence or the field boundary. Like another invasive species which I recently wrote about, the Himalayan balsam, Helianthus tuberosus is particularly troublesome if the plant colonizes river banks, for the same reason. It dies back during winter, leaving the river banks much more exposed to the danger of erosion during winter and spring floods.
So, dear readers, bon appetit! But if you want to grow these tubers please make sure they don’t escape from your garden!
