The Story Behind the Dish

A Little Luxury in Every Spoonful

There is something captivating about transforming an overlooked vegetable into the centrepiece of an extraordinary meal.

Jerusalem artichokes may be modest in appearance, but beneath their irregular skins lies a delicate, nutty sweetness that becomes beautifully mellow when cooked.

For this Nicol Retailer creation, Jerusalem artichokes are gently simmered with sweet leeks and banana shallots, then blended into a velvety soup.

Golden king prawns bring a subtle seafood sweetness. Fine potato ribbons add an irresistible crunch, while emerald-green chive oil introduces freshness and colour.

“The secret to memorable cooking is not how many ingredients you use, but how beautifully they work together.”

The result is a dish that feels special enough for a dinner party, yet remains achievable in the home kitchen.

Ingredient Spotlight

Why Jerusalem Artichokes Deserve Your Attention

Despite their name, Jerusalem artichokes are neither from Jerusalem nor the same vegetable as globe artichokes. They are edible tubers of a sunflower species, valued for their gently sweet, earthy and nutty character.

They are especially appealing in cooler-weather cooking, when their flavour lends itself to silky soups, delicate purées and roasted vegetable dishes.

In this recipe, their natural character remains the star. The supporting ingredients are chosen to enhance rather than overwhelm it.

Instructions

Prepare the vegetables

Scrub and trim the Jerusalem artichokes, removing any damaged areas. Chop evenly and keep in cold water with a little lemon juice until needed to minimise discolouration. Wash and finely slice the leeks.

Cook the soup

Melt 25g butter with 15ml olive oil in a heavy-bottomed saucepan. Add the leeks and banana shallots and cook gently for 8–10 minutes until softened without browning.
Add the garlic, drained Jerusalem artichokes and thyme. Cook for 2 minutes, stirring. Add 600ml vegetable stock and simmer gently for 20–25 minutes until the artichokes are tender.

Blend and finish

Remove the thyme stems. Blend the soup until completely smooth, then pass through a fine-mesh sieve into a clean saucepan.
Stir in 80ml double cream and 10ml lemon juice. Adjust with up to 100ml reserved stock until silky and pourable. Season with salt and white pepper. Keep warm without boiling.

Make the chive oil

Blanch the chives in boiling water for 10 seconds and refresh immediately in iced water. Squeeze completely dry, blend with 60ml extra virgin olive oil until bright green and strain through a fine sieve.

Fry the potato ribbons

Use a mandoline or peeler to cut the potato into very thin ribbons. Rinse briefly and dry thoroughly.
Heat vegetable oil in a suitable deep saucepan to 170°C. Fry ribbons in small batches for approximately 2–3 minutes until golden and crisp. Remove with a slotted spoon, drain on kitchen paper and season lightly. Never leave hot oil unattended.

Sear the king prawns

Pat the raw king prawns dry. Heat 15ml olive oil in a frying pan over medium-high heat. Sear the prawns in a single layer for approximately 1–2 minutes per side, depending on size, until opaque and cooked through.
Add 15g butter, 10ml lemon juice and ½ tsp lemon zest. Toss briefly to glaze, then finish with 5g chopped chives, sea salt and black pepper.

Plate and serve

Arrange approximately three seared prawns in each of four warmed shallow bowls. Pour the hot Jerusalem artichoke velouté around them, leaving the prawns visible. Add a small nest of crispy potato ribbons and finish with droplets of bright green chive oil. Serve immediately.

Notes

Chef’s Tips for a Restaurant-Quality Finish

1. Develop the natural sweetness – Cook the leeks and banana shallots slowly over a gentle heat without browning. This creates a delicate, sweet foundation that complements the nutty flavour of Jerusalem artichokes.

2. Achieve a silky-smooth texture – Blend the soup thoroughly and pass it through a fine-mesh sieve. Add the vegetable stock gradually to achieve a luxurious, pourable consistency without making the soup too thin.

3. Perfectly sear the king prawns – Pat the prawns dry before cooking. Sear in a hot pan until lightly golden, opaque and cooked through. Finish with butter, lemon zest and fresh chives for a delicate, aromatic glaze.

4. Keep the potato ribbons crisp – Slice the potatoes as thinly as possible, dry thoroughly and fry in small batches. Add them immediately before serving to preserve their golden colour and delicate crunch.

5. Balance the flavours – Finish the soup with fresh lemon juice to lift the earthy Jerusalem artichokes and balance the richness of the cream.

6. Refine the presentation – Serve in warmed, shallow white bowls. Arrange the prawns centrally, pour the soup around them and finish with precise droplets of vibrant chive oil and a small nest of crispy potato ribbons.

Vegan Variation – Jerusalem Artichoke & Leek Soup with Golden King Oyster Mushrooms

Transform this recipe into an elegant plant-based starter without compromising its luxurious texture or presentation.

Ingredient substitutions:
– Replace the 240g king prawns with 240g king oyster mushrooms, sliced lengthways into thick pieces.
– Replace the 40g unsalted butter used across the recipe with plant-based butter.
– Replace the 80ml double cream with 80ml unsweetened oat cream or another suitable plant-based cooking cream.
– Use vegetable stock suitable for vegans.

Cooking instructions

Prepare the Jerusalem artichoke and leek soup using the original method, substituting plant-based butter and cream.

Heat 15ml olive oil in a frying pan over medium-high heat. Add the king oyster mushrooms and sear for approximately 3–4 minutes on each side until golden brown and tender.

Finish with plant-based butter, fresh lemon juice, lemon zest and chopped chives.

Serve the golden mushrooms in the centre of each bowl, surrounded by the silky Jerusalem artichoke soup. Garnish with crispy potato ribbons and vibrant chive oil.

Chef’s recommendation – King oyster mushrooms provide a satisfying, meaty texture and delicate savoury flavour, making them an excellent alternative to king prawns.

Gluten-Free Variation

The original recipe does not require flour or breadcrumbs. To prepare a gluten-free version, use certified gluten-free vegetable stock and check that all packaged ingredients are suitable.

Storage and Serving

Refrigerate the soup promptly in a covered container and use within two days. Reheat until thoroughly hot. Prepare the prawns or mushrooms, crispy potato ribbons and chive oil separately for the best presentation.

The Nicol Edit / Beyond the Recipe

The Finishing Touch Is Everything

A beautiful dish is rarely defined by one ingredient. It is the harmony of flavour, texture and thoughtful detail that makes it unforgettable.

Now that you have discovered the recipe, explore the chef’s techniques, elegant variations and finishing touches that elevate this Jerusalem artichoke soup from comforting to exceptional.

01 / The Chef’s Notes

Five Secrets to a Restaurant-Quality Finish

Luxury in cooking often comes from restraint. A little patience, careful temperature control and an understanding of texture can transform a familiar ingredient into something remarkable.

01 — FLAVOUR

Let the Leeks Whisper

Slowly soften the leeks and shallots without browning. Their gentle sweetness should support the Jerusalem artichokes, never compete with them.

02 — TEXTURE

Silk, Not Simply Smooth

Blend the soup thoroughly once the artichokes are completely tender. Passing it through a fine sieve creates a delicate, refined finish.

03 — PRECISION

Golden, Succulent Prawns

Dry the king prawns before searing. Cook until opaque and fully cooked, then finish with lemon and chives. Avoid prolonged cooking, which can make the flesh tough.

04 — CONTRAST

The Perfect Golden Crunch

Slice the potato ribbons very thinly, rinse and dry them thoroughly. Fry in small batches and add at the last moment to preserve their crispness.

05 — PRESENTATION

Finish with a Light Hand

Add small droplets of bright chive oil rather than a heavy drizzle. Allow the ivory soup, golden prawns and green oil to remain visually distinct.

“The most memorable plates are often those where every detail feels effortless, yet nothing has been left to chance.”

02 / The Plant-Based Edit

A Beautifully Different Interpretation

Jerusalem Artichoke Velouté with Golden King Oyster Mushrooms.

The elegance of this dish does not depend on seafood. For a sophisticated vegan alternative, replace the king prawns with thick slices of king oyster mushrooms.

Sear the mushrooms until golden on both sides, allowing their savoury flavour and satisfying texture to develop. Finish with fresh lemon zest, lemon juice and chives.

Replace the dairy butter with plant-based butter, use unsweetened oat cooking cream and choose a suitable vegan vegetable stock.

Keep the crisp potato ribbons and vibrant chive oil. Together, they preserve the contrast and elegance of the original dish.

The Chef’s Recommendation

Allow the mushrooms to develop a deep golden surface before turning them. Their rich savoury character provides a wonderful counterpoint to the naturally sweet Jerusalem artichokes.

Explore Fresh Vegetables

Check product availability and dietary suitability before purchasing.

03 / The Entertaining Edit

Host Beautifully. Cook Calmly.

The pleasure of hosting should not be lost in the kitchen. With a little organisation, this elegant starter can be served with confidence and minimal last-minute fuss.

The Day Before

Prepare the soup, cool promptly and refrigerate in a covered container.

Earlier That Day

Prepare the chive oil, organise the ingredients and arrange your serving bowls.

Before Guests Sit

Reheat the soup thoroughly. Sear the prawns and fry the potato ribbons fresh.

The Final Moment

Arrange the prawns, pour the soup and finish with potato ribbons and chive oil.

“The finest hospitality feels relaxed. The preparation is thoughtful; the experience is effortless.”

04 / The Menu Edit

Build a Beautiful Menu Around the Soup

A well-considered menu is about rhythm. Each course should complement the next without overwhelming the palate.

THE ACCOMPANIMENT

Warm Artisan Bread

A small slice of toasted sourdough or rustic bread offers a simple contrast to the creamy soup.

THE FRESH ELEMENT

Delicate Green Leaves

A lightly dressed salad with lemon and olive oil refreshes the palate between courses.

THE MAIN COURSE

Simply Prepared Fish

Follow with a delicate fish dish, seasonal vegetables and a restrained citrus dressing.

THE PLANT-BASED MENU

Seasonal Vegetables

Pair the mushroom variation with a vegetable-led main course celebrating fresh herbs and seasonal produce.

05 / The Ingredient Journal

Everything You Wanted to Know

A little ingredient knowledge can make every recipe more rewarding.

What do Jerusalem artichokes taste like?

They have a gently sweet, earthy and nutty flavour. Cooking makes them tender and particularly suitable for soups and purées.

Should Jerusalem artichokes be peeled?

Not necessarily. Their thin skins are edible when thoroughly cleaned. Peeling can produce a paler, more refined soup.

Can the soup be prepared in advance?

Yes. Prepare the soup ahead, cool promptly and refrigerate. Reheat until thoroughly hot. Cook the prawns and potato ribbons shortly before serving.

Can I freeze Jerusalem artichoke soup?

Yes. Freeze the soup base before adding cream, in suitable airtight containers. For best quality, use within two to three months. Defrost safely and reheat thoroughly.

Is the recipe gluten-free?

The recipe does not require flour or breadcrumbs. Always verify that the stock and other packaged ingredients are suitable.

Can Jerusalem artichokes cause bloating?

Yes. They contain inulin, a carbohydrate that can cause wind or bloating in some people. Modest starter portions may be preferable.

What can replace the king prawns?

Golden-seared king oyster mushrooms make an excellent plant-based alternative. Use plant-based butter, cream and vegan stock for the complete vegan variation.
