Here, you cook the bass in an aromatic onion
broth but serve it in a much more delicate fennel
broth.
8 cups (2 quarts) vegetable broth
4 fennel bulbs, trimmed, with the small
feathery fronds minced and reserved
3 cups water
1⁄4 cup dry white wine or dry vermouth
1 large onion, quartered
1 celery rib, cut into chunks
10 black peppercorns
4 parsley sprigs
Six 4- to 6-ounce skin-on black, striped,
spotted, or sea bass fi llets (see Note)
1⁄2 teaspoon kosher or sea salt, or to taste
How to make
Bass in a Fennel Broth
Pour the broth into a large saucepan and set
it over high heat. Thinly slice the fennel and
add it to the broth once it comes to a boil.
Cover tightly, reduce the heat to very low, and
simmer very slowly for 1 hour. Strain over a large
bowl, then pour back into the large saucepan.
Set aside, covered, off the heat. Discard the
sliced fennel.
Combine the water, wine or vermouth, onion,
celery, peppercorns, parsley, and salt in a medium
saucepan set over high heat. Bring the mixture to
a boil, cover, reduce the heat to low, and simmer
very slowly for 30 minutes.
Strain the onion mixture through a fi ne-mesh
sieve and into a large sauté pan or high-sided skillet;
set over medium-high heat and bring to a simmer.
Also place the fennel infusion in its saucepan
over medium-low heat.
Score the skin on the bass fi llets in three or
four places with a sharp knife. Slip them into the
strained onion broth, cover, and poach until the
fi llets are opaque and can be fl aked at their thinnest
part with a fork, about 5 minutes.
Gently transfer the fi llets to four large soup
bowls. Ladle the hot fennel broth over them. Sprinkle
a few feathery fennel fronds over each bowl
and garnish with salt.
