Prepare the fumet: roast the rock fish in the oven at 200 °C for 20 minutes.
In a pot, sauté the onion, garlic, leek, and fennel with the olive oil. Add the roasted fish and cover with water. Cook for 20 minutes and strain the broth.
For the beurre blanc, separately reduce the white wine, cream, and fumet until each has reduced by about half.
Combine the three reductions and add the miso paste. Adjust seasoning with salt and pepper and keep warm.
Cut the vegetables into even pieces and blanch them for about 90 seconds in boiling water. Cool quickly in ice water, drain, and reserve.
Confit the wild Alaskan gindara in the olive oil with the thyme, rosemary, and cayenne at 80 °C for about 5 minutes.
Add the vegetables to the beurre blanc and cook for 1 minute so they absorb the sauce.
To plate, first arrange the vegetables with the sauce and place the confit gindara on top.
