It is a masterclass in modern coastal fine dining, balancing deep umami notes with refined coastal freshness.

🥗 Ingredients

The John Dory

  • 4 pieces John Dory Fillets (approx. 150g each, skin removed and pin-boned)
  • 250 grams Unsalted Cultured Butter (high quality, for poaching)
  • 3 sprigs Lemon Thyme (fresh)
  • 1 pinch Maldon Sea Salt (to taste)

Jerusalem Artichoke Textures

  • 500 grams Jerusalem Artichokes (Sunchokes) (peeled and sliced thinly for the puree)
  • 300 ml Whole Milk (for simmering)
  • 100 ml Heavy Cream (high fat content)
  • 1 piece Large Jerusalem Artichoke (reserved for crisps)
  • 200 ml Grapeseed Oil (for frying crisps)

Caviar Service & Garnish

  • 50 grams Osetra Caviar (chilled)
  • 1 small bunch Chives (finely minced)
  • 1 handful Micro-Sorrel or Sea Aster (for garnish)
  • 1 teaspoon Lemon Juice (freshly squeezed)

👨‍🍳 Instructions

  1. 1

    Begin by preparing the Jerusalem artichoke puree: Place the peeled and sliced artichokes in a heavy-bottomed saucepan with the milk, cream, and a pinch of salt. Simmer over medium-low heat for 20-25 minutes until the artichokes are completely tender.

  2. 2

    While the artichokes simmer, prepare the crisps. Use a mandoline to slice the reserved whole artichoke into paper-thin rounds. Heat grapeseed oil to 160°C (320°F) and fry the slices until golden and crisp. Drain on paper towels and season immediately with fine salt.

  3. 3

    Once the artichokes in the pan are soft, strain the liquid (reserve it!) and transfer the solids to a high-speed blender. Blitz on high, adding just enough of the cooking liquid to achieve a perfectly smooth, velvet-like consistency. Pass through a fine-mesh chinois and keep warm.

  4. 4

    Prepare the poaching bath for the fish. In a wide, shallow pan, melt the cultured butter over low heat. Add the lemon thyme sprigs and bring the butter to a steady temperature of 60°C (140°F). Use a digital thermometer to ensure it does not exceed this.

  5. 5

    Season the John Dory fillets lightly with sea salt. Gently submerge the fillets into the warm butter. Poach for 8-10 minutes, depending on thickness, until the flesh is just opaque and flakes gently under light pressure.

  6. 6

    While the fish poaches, warm your serving plates. In fine dining, the temperature of the plate is as critical as the food.

  7. 7

    Carefully lift the John Dory from the butter using a slotted fish spatula. Place onto a tray lined with paper towels for 30 seconds to remove excess fat. Brush the top with a tiny drop of lemon juice.

  8. 8

    To plate, place a generous spoonful of the Jerusalem artichoke velouté in the center of each plate and use the back of the spoon to create a smooth circle.

  9. 9

    Place the poached John Dory fillet directly onto the puree. Arrange 3-4 artichoke crisps artfully against the side of the fish.

  10. 10

    Using a mother-of-pearl spoon, place a beautiful quenelle of Osetra caviar directly on top of the fish. The cold caviar against the warm fish creates a stunning sensory contrast.

  11. 11

    Scatter the finely minced chives and micro-greens around the plate for a touch of acidity and color. Serve immediately.

💡 Chef's Tips

Always use a digital thermometer when poaching fish; if the butter gets too hot, the fish will become tough rather than buttery. Jerusalem artichokes oxidize quickly; keep them submerged in lemon water after peeling until you are ready to cook them. For the smoothest puree, don't be afraid to blend for a full 2-3 minutes; the friction helps create that 'fine dining' silkiness. When handling caviar, never use a metal spoon as it can oxidize the delicate roe and alter the flavor profile.

🍽️ Serving Suggestions

Pair with a crisp, mineral-heavy Chablis or a vintage Blanc de Blancs Champagne to cut through the richness of the butter. Serve with a side of steamed sea kale or samphire for an extra touch of coastal authenticity. A crusty piece of warm sourdough on the side is perfect for mopping up any remaining artichoke velouté. Follow this dish with a light, citrus-based palate cleanser like a lemon verbena granita.
