About this dish
Built like a lamb navarin but grounded in a proper shellfish bisque, this dish roasts prawn shells with tomato paste and aromatics before folding in spring vegetables, so every spoonful carries real crustacean depth.

Method
Peel the prawns, reserving all shells and heads. Devein the prawns and pat them dry. Keep refrigerated until needed.
Heat 1 tbsp olive oil in a large heavy-based saucepan over high heat until smoking. Add the prawn shells and heads and cook, stirring, for 4-5 minutes until they turn deep orange and begin to catch on the base.
Push the shells to one side, reduce heat to medium, and stir in the tomato paste. Cook the paste for 2 minutes until it darkens slightly and smells nutty.
Pour in the white wine and deglaze, scraping up all the caramelised bits. Let the wine reduce for 3 minutes until almost halved.
Pour in the fish stock, add the bouquet garni, and simmer over low heat for 20 minutes. Strain through a fine-mesh sieve, pressing the shells firmly to extract every drop of liquid. Discard the solids and set the bisque base aside.
In a wide, deep sauté pan, melt 2 tbsp butter with the remaining 1 tbsp olive oil over medium heat. Add the onion and cook for 5 minutes until soft and translucent, without colouring.
Add the garlic and stir for 1 minute until fragrant.
Sprinkle the flour over the onion and garlic and stir constantly for 2 minutes to cook out the raw flour taste.
Gradually ladle in the strained bisque base, stirring continuously to prevent lumps. Bring to a gentle simmer.
Add the carrots, turnips, potatoes, sugar, and a pinch of salt. Cover and cook over low heat for 20 minutes until the vegetables are just tender when pierced with a knife.
Add the green beans and cook, uncovered, for 4 minutes until bright green and just tender.
Add the peas and cook for 2 minutes until heated through.
Add the prawns to the pan in a single layer and cook for 3-4 minutes, turning once, until they are pink and opaque throughout. Use an instant-read thermometer to confirm they have reached an internal temperature of 63°C. Do not overcook.
Remove from heat. Stir in the remaining butter, the lemon zest, parsley, and tarragon. Taste and adjust seasoning with salt, white pepper, and a small squeeze of lemon juice if needed. Serve immediately in wide, shallow bowls.
