Why fresh potatoes are the perfect package: Tasty, nutritious, and as cheap as chips

​Spuds have fallen out of favour as low-carb diets and fancy grains have conquered our plates. But we're missing a trick, says agronomist and tuber fan Alan Wilson

Can you imagine a world with no Sunday roast? A place where our beloved roast potatoes have been comprehensively ousted by salty chips and crisps, bringing the demise of pink roast beef, juicy chicken and tender pork in their wake, so that pubs no longer draw in the Sunday crowds with their prized roast-with-all-the-trimmings and Mum has no reason to feed you over the weekend?

Alan Wilson can. He links a considerable drop in potato consumption to our unwillingness to buy, grow and cook potatoes, and eat them together as part of a family meal.

Last year, Wilson planted about 30 varieties of potato in his Hampshire garden. “The potato is the whole package, and I eat them almost every day,” he says, looking forward to a new season of planting and harvesting, although he's promised his wife he'll cut down a little this year. “I love harvesting the best new potatoes, coming in from the garden and eating them straight away. Life doesn't get much better than that.” If you think how eagerly we demand ripeness and freshness from other produce, it begins to look odd that we'll let potatoes moulder away but still expect great things from them.

As Waitrose's technical manager for agronomy, Wilson knows a thing or two about fruit and veg, but spuds are his passion. He first tried to grow them as a teenager 40 years ago, but 1976 was the year of the UK's last severe drought, and nothing came up. He was put off, but only temporarily. Soon he got to know many varieties of potato – he details an incredible 400 in his new book, The People's Potatoes – and later joined Waitrose as a potato buyer.

“A potato is a complete food, and it goes back centuries,” he says. “Baked in its jacket or steamed, it's very nutritious and provides decent amounts of our vitamin C requirements.” Although often dismissed as starchy and lacking in nutrients – certainly not a “health” food – a 100g portion of potatoes supplies 32 per cent of our daily vitamin C requirements, 12 per cent of our potassium needs and 8 per cent dietary fibre. And, of course, they are cheap as, well, chips.

Now for the bad news. “Unfortunately, if you want to cover them in butter or make them into chips with salt and vinegar, we're creating a very different experience for ourselves,” he says.

Potatoes came to the UK from the Americas in the 16th century and soon became an indispensable part of our diet, as they are around much of the world. Don't forget that jacket potatoes were a popular, filling and tasty street food long before any of us had heard of dirty burgers or pulled pork, and that roast potatoes are vital components of Sunday roasts and Christmas dinners. But Wilson fears that we don't know enough about how many different and delicious varieties of potato there are, and how easy they are to grow. “You'd have to ask quite a few people in the street before you find someone who can name three,” he says. “King Edward is the obvious one but, beyond that, you'd struggle.”

We tend to think of potatoes as either waxy or floury. Popular floury varieties, great for baking, mashing and chips, are King Edward and Maris Piper. They disintegrate on boiling, however; so instead you need something waxy such as a Charlotte or any new potato, or the Red Duke of York, one of Wilson's personal favourites.

Wilson has created a website, thepeoplespotatoes.com, to campaign for people to grow and eat more potatoes. It remains something of a staple food in the UK, but the introduction of competitors into our diets – pasta and rice, and more recently the influx of interesting grains such as couscous, quinoa, spelt and their many cousins – means that the amount of potatoes we're consuming has fallen. In 1993, Wilson writes in his book, each person in the UK was consuming 73kg of fresh potatoes and 36kg of processed potatoes (in the form of chips, crisps and ready-prepared meals).

“It's alarming,” he says. “We're a nation that wants to be more healthy, yet often when we're consuming this nutritious veg it's been processed. Once that happens, we don't know what variety it is. That's the path we're on and the future looks quite grim.”

Alan and his book

Wilson predicts that at this rate, within a decade we'll only be eating 25kg of fresh potatoes each per year, which could mean that more varieties fall out of favour. Already, 92 per cent of all fresh potatoes sold reach us via supermarkets, so the route to a shop stocking new varieties is narrow, and based on “corporate interpretations of consumer needs”, he says.

Of course, it is also a very powerful route. Wilson has ensured that Waitrose stocks a good selection: it is currently selling Maris Piper, King Edward, Desiree/Mozart, Charlotte, Harlequin, Roseval and a few types of unspecified new, salad and baking potatoes. According to M&S, our favourites are King Edwards and Desiree, which, along with new potatoes Maris Peer and Season Gold, are showing sales increases this year, as is its Chopin variety.

The supermarket chain Booth's champions the taste of fresh potatoes, and offers “Dug Today” potatoes, which are unearthed in the early hours by Lancashire grower Sean Mallinson and reach shelves by breakfast-time. “There are so many brilliant British varieties to enjoy,” says buyer Thomas Hargreaves. “In line with overall market reports, we have seen a slight decline in potato sales; but consumers seem to view potatoes as a treat, rather than something for every day.”

Hargreaves says that there are great sales in heritage potato ranges, such as the Pink Fir Apple, a relative of the first potatoes brought over from South America by Walter Raleigh. Peru is well known for its potatoes and as the cuisine starts to become known over here, chefs such as Robert Ortiz, executive chef at London's two Lima restaurants, are teaching us to look at our spuds in new ways. Potatoes are found in every kitchen in Peru, he says, and about 25 varieties are used regularly, far more than in this country.

Are we stuck in dull potato habits in the UK? “One of the reasons potatoes may be perceived as boring over here might be that people eat baked potatoes quite a lot and there is a tendency to cook them in the microwave, which I believe takes away the majority of the flavour and alters its texture,” says Ortiz.

He is impressed by some of the varieties growing in the UK, and at home often makes a simple and traditional Peruvian potato dish called a “causa”, in which boiled or roasted potatoes are mashed, mixed with lime, chilli and coriander, and then served with a topping, which might be chicken, tuna or prawns.

While you're experimenting, don't forget our classic potato dishes. “If you throw out the potato, you'll also throw out the Sunday lunch, and the Brussels sprout and the carrots and swedes along with it, so the great British Sunday lunch is poised to be a thing of the past.”

But he also expects the seed potato market to improve. If you go to a “potato day” events held around the country where seeds and plants are sold and expert advice is available, you'll find thousands of people with a similar passion for spuds. “The natural desire within us all to grow food may just be reawakening,” says Wilson. “If that is the case, there is even more reason to cherish the varieties we have now to ensure that the potatoes of the people are maintained for the people.

Potato rosti

Ingredients to serve 4

4 potatoes

Peel and grate potatoes, squeezing out the moisture. Grate the onion and add to the potato, seasoning well.

Potato, radish and chervil warm salad

Ingredients to serve 4

Veg stock or bouillon

800g new or salad potatoes, cut in half, or quarter if large

12 radishes (keep their tops if bunched), trimmed of long roots

2 tablespoons sherry vinegar

50g butter

Pinch of sugar

2 tablespoons chervil leaves (or use parsley)

Bring a pan of veg stock to the boil (or a pan of water with a little bouillon). Add the potatoes and cook until just tender, about 10-12 minutes. Remove with a slotted spoon to a serving bowl. Add the radishes and cook for 3-4 minutes, depending on size. Remove and add to the potatoes (cut some of the larger ones in half, if you like).

Drain off most of the stock, leaving about 3 tablespoons. Add the vinegar, butter and sugar to the pan.

Boil to reduce a little, until almost syrupy, wilting in any radish tops (if you have them) at the end. Toss with the potatoes, radishes and chervil. Season to taste.
