Scallop Tartare with Vadouvan and Pickled Vegetables

This is the kind of plate that sets the tone for the whole meal — delicate, composed, quietly ambitious. The whole dish plays on the contrast between hot and cold: ice-cold raw scallop, diced to a clean brunoise and dressed lightly with lemon and chives, dropped straight onto a pool of hot, glossy vadouvan butter sauce so the two temperatures meet on the tongue. The vadouvan is the hook — a French-style curry blend built around slow-cooked shallot and fenugreek, gentler and more savoury than garam masala, which plays beautifully against the sweetness of the scallop without flattening it.

How to prepare

The build order matters more than anything else here. Start the pickles first so they have at least 20 minutes to take on flavour (and up to two days ahead if you want). While they’re pickling, dice the scallop and keep it on ice, and get the reduction for the butter sauce ready. The butter itself is mounted at the very last minute: this is a hot sauce, and the whole dish lives or dies on the temperature contrast between scorching sauce and ice-cold tartare. Mount the butter, dress the scallop, build the plate — all in under three minutes.

Start the pickle by bringing the vinegar (100ml), water (100ml), sugar (40g), salt (1 teaspoon), bay leaf, coriander seeds and mustard seeds to a simmer in a small saucepan, stirring just until the sugar dissolves. Take it off the heat. Slice the beetroots and carrot into 2mm coins on a mandoline — thin enough that they’ll take on flavour quickly and bend a little on the plate, thick enough that they hold shape when you pick them up. Keep the golden and red beetroot in separate bowls, because the red will bleed into anything it touches within a minute. Pour the warm pickle liquid over each and leave them to pickle at room temperature for at least 20 minutes. They’re best after about an hour, still bright and crunchy with a clean sweet-sour hit.

Start the butter sauce by building its flavour base — a classic beurre blanc-style reduction. In a small saucepan, simmer the finely diced shallot, white wine (60ml) and white wine vinegar (1 tablespoon) over medium heat until only about a tablespoon of syrupy liquid remains, 4-5 minutes. The reduction gives the sauce its acidity and backbone; without it, you just have melted butter. Stir in the double cream (2 tablespoons) and simmer for one more minute — the cream is a stabiliser that makes the sauce more forgiving once you start mounting butter, especially helpful when you’re juggling several components at service. Pull off the heat and hold the reduction until the rest of the plate is ready to go.

If you’re using a shop-bought vadouvan blend — Roellinger, Terre Exotique, or a good French spice merchant’s version — the flavour will already be rounded and savoury. You’ll bloom it directly in the finished hot butter sauce at the last minute, which extracts the spice oils into all that butter and gives you a vivid, amber-gold colour without any risk of scorching.

The scallop itself needs nothing clever, just a sharp knife, a cold bowl, and respect for the ingredient. Dry each scallop well with kitchen paper — surface moisture is the enemy of a clean cut. With a very sharp, thin-bladed knife, slice each scallop horizontally into three 5mm discs, then slice each disc into 5mm strips, then crosswise into neat 5mm cubes. This is a knife-cut exercise: the more uniform the dice, the more elegant the tartare will look and the more evenly it’ll take seasoning. Slide the diced scallop straight into a metal bowl set over a second bowl of ice — cold scallop is firm scallop, and the whole dish relies on it staying ice-cold right up until the moment it meets the sauce.

Dress the tartare within a few minutes of serving. Add the very finely diced shallot, lemon juice, lemon zest, olive oil and chives, then season with flaky salt and a few grinds of white pepper. White pepper, not black — it disappears into the dish visually and has a gentler, more floral heat that suits raw shellfish. Fold gently with a spoon, taste, and adjust. The tartare should taste clean, sweet, briny and citrus-bright, with a soft allium backbone from the shallot. Season boldly — there’s a lot of rich butter sauce underneath, and an underseasoned tartare will read as flat. Once dressed, plate within two or three minutes — the acid from the lemon will slowly start to cure the scallop and turn the texture from silky to chalky if you let it sit.

Now mount the sauce. Bring the reduction back to the lowest possible heat — or pull it just off the flame entirely — and whisk in the cold butter (120g) a few cubes at a time, letting each addition emulsify fully before the next goes in. You’re looking for that classic beurre blanc behaviour: the sauce turns from thin and translucent to glossy, opaque and thick enough to coat the back of a spoon. The key is temperature control, ideally 60-70°C, because if it sees a full simmer the emulsion will break and you’ll be left with a greasy puddle. A kitchen thermometer takes the guesswork out of this and is worth having if you make mounted butter sauces. Once every cube is in, whisk in the vadouvan (2 teaspoons) and let it bloom directly in the hot butter for about 30 seconds — you’ll see the sauce shift to a vivid amber-gold and the kitchen will smell unmistakably of toasted onion, fenugreek and warm curry. Finish with the lemon juice (1 teaspoon), season with fine salt, and hold over a pan of hot (not boiling) water for no more than five minutes before plating. This sauce does not reheat, so time it to the second.

To plate, a scrubbed scallop shell is the classic vessel and the one the dish is obviously built for — but a small chilled plate or shallow bowl also works. Spoon two tablespoons of the piping- hot vadouvan butter sauce into each vessel and give it a gentle shake so it settles into a neat pool. Immediately spoon the dressed tartare into the centre, shaping it into a loose quenelle or a rough mound that lets the yellow sauce show around the edges. The moment the cold scallop touches the hot sauce is the whole point of the dish — the edges of the tartare warm and release their sweetness while the centre stays icy and bright, and the vadouvan aroma blooms upwards as it hits the cold fish. Drain the pickles well and arrange three or four coins of each colour over and around the tartare — alternating the golden and red beetroot with the carrot gives you the best contrast against the pale scallop. Scatter the buttery toasted puffed rice or panko over the top for crunch, and finish with a few delicate leaves of micro coriander or chervil. Serve immediately, before the sauce cools and the whole hot-cold effect is lost.

Bonus points

• Make your own vadouvan: Sweat 200g finely diced shallot and 150g diced onion in butter over very low heat for 40-50 minutes until deeply caramelised. Stir in 2 teaspoons each of ground cumin, coriander and fenugreek, 1 teaspoon each of turmeric and mustard seeds, 1/2 teaspoon each of ground cardamom and black pepper, and a pinch of clove. Dry in a low oven (90°C) for 2-3 hours until crumbly, then blitz briefly in a grinder. Keeps 2 months in a jar and is miles better than most shop versions.
• Add sea urchin uni: Lay a single tongue of fresh uni over the tartare just before serving. The custardy sweetness plays incredibly well with both the scallop and the vadouvan.
• Finish with a drizzle of vadouvan oil: Infuse neutral oil with bloomed vadouvan over low heat for 30 minutes, then strain. A few drops around the plate give an extra layer of spice aroma and a restaurant-style golden finish.
• Swap in turnip and radish: If beetroot isn’t in season or you want a paler palette, pickle thin slices of young turnip, breakfast radish and fennel instead. The finished plate reads cleaner and more monochromatic.
• Apple for acid and crunch: A small dice of Granny Smith, 3mm cubes, folded into the tartare at the last second brightens the dish and adds snap. Use sparingly — about 1 tablespoon total — so it supports rather than dominates.
• Finger lime pearls: Break open a finger lime and scatter the citrus pearls over the tartare. They pop on the tongue and give tiny bursts of acidity through the bite.
• Serve in the shell, on salt: Plate the scallop shells on a bed of coarse sea salt on a long tray or plank so they sit level and look like they’ve just come out of the sea. Great for the pass at a dinner party.

Serving

This is a first course, full stop — the portion is small, the flavours are concentrated, and a couple of spoonfuls is exactly right to wake up the palate without filling anyone up. Chill your shells or plates in the fridge for at least 15 minutes before you build the dish — a cold vessel helps preserve the temperature contrast with the hot butter sauce, which is the whole architecture of the plate.

Serve immediately after plating, and mean it. The dish is engineered around the first bite: hot, glossy, spiced butter underneath; ice-cold, citrus-bright scallop on top; sweet-sour crunch from the pickles around the edges. Give everyone a minute too long and the sauce cools, the contrast fades, and you end up with a much duller plate. Give each guest a small spoon — an espresso or demitasse spoon is perfect — and encourage them to drag it through the pool of sauce so each bite carries some scallop, some pickle, some sauce and a little of the toasted crunch on top. If you’re using the scallop shells as vessels, set them on a folded napkin or a bed of coarse sea salt so they sit flat and don’t rock on the table.

For wine, the obvious move is a taut, mineral white with enough aromatics to meet the vadouvan without fighting the scallop. A dry Alsace Riesling or a good Pinot Gris is spot-on — they have the salinity for the shellfish and a slight roundness that matches the curried butter. A blanc de blancs Champagne is the celebration option and carves cleanly through the richness of the emulsion. For something unexpected, try a dry amontillado sherry served cold in a small glass — its nuttiness mirrors the fenugreek in the vadouvan in a way that surprises everyone at the table.
