Roast the eggplant on a baking sheet until tender, about 50 minutes.
-

Transfer the eggplant to a bowl, cover with plastic wrap and let cool slightly.
-

Discard the cinnamon and peel the eggplant.

In a microwave-safe bowl, cover the raisins with water and microwave at high power until plumped, about 30 seconds.

Drain the raisins and transfer them to a blender.

In a bowl, mix the kosher salt with the water until it is the consistency of moist sand.

On a parchment paperlined baking sheet, mound one-fourth of the salt slightly larger than the fish.

Lay the fish on the salt and fill its cavity with the bay leaves and lemon wedges.

13
Poke a short skewer into the thickest part of the fish, just behind the head.
-
14
Pack the remaining kosher salt over and around the fish to enclose it; leave the skewer visible.

15
Bake the fish for about 35 minutes, until an instant-read thermometer inserted in the skewer hole registers 135.

Let the fish rest for 5 minutes; crack and remove the salt crust.

Serve the fish without the skin, with the eggplant puree alongside.
