🐟 Block 17–18: Seafood — Fish

← Block 15–16: Beef | Block 19–20: Shellfish →

"Fish is the most immediate teacher in the kitchen. You overcooked it? You know in 30 seconds. The window for perfection is narrow — narrow enough that it forces your full attention every time."

Before You Start Block 17

Lab 4 — Fillet a Whole Fish (optional)

Skill: Breaking down a whole round fish into two clean fillets. This is the single most useful fish skill you can own — when you can fillet, you buy whole fish (cheaper, fresher, more honest), and you understand why a halibut fillet costs what it does.

📖 Read and watch before starting: Serious Eats — How to Fillet a Fish — the Kenji walkthrough is the clearest English-language video on this.

The technique for a round fish (salmon, sea bass, snapper, branzino): 1. Find the backbone — place the fish belly-down; feel the spine through the flesh 2. First cut — score behind the head diagonally to the backbone; don't cut through 3. Run the knife along the spine — blade angled slightly toward the bone, long smooth strokes, let the backbone guide you; use the rib cage as a fence 4. Fillet off the ribcage — once past the spine, angle the knife to follow the rib curve; you should hear the blade scraping bone (that's correct — you're not wasting meat that way) 5. Pin bones — run your finger down the centerline of the fillet; tiny bones perpendicular to the flesh. Pull with needle-nose pliers or fish tweezers, always pulling in the direction the bone points 6. Repeat for the second fillet

Freshness signals — know these before you go to the fishmonger: - Eyes: clear and slightly bulging. Cloudy or sunken = not fresh - Gills: bright red when fresh; brown or grey = older fish - Smell: clean, oceanic, or neutral. "Fishy" smell is TMA (trimethylamine) — bacterial decomposition. Fresh fish smells like the sea, not like fish - Flesh: springs back when pressed; doesn't hold the indentation - "Sushi-grade" has no legal definition — it means the seller is comfortable selling it raw. Ask your fishmonger directly

Full Meal: Fillet and cook the fish in whatever style you prefer tonight — the miso glaze is already prepped for later in the block, or use the earlier pan-sear technique (crispy skin pan sear). You've broken it down yourself. That changes how it tastes.

Why this matters beyond skills: A whole 2 lb branzino costs $12–14 at a good fishmonger. The same fish sold as fillets costs $18–22. You just learned where $6–8 of the price comes from — and you can have fresher fish for less money.

Block 17 — The Fundamentals of Fish Cookery

The central principle this week: Fish cooks faster than you think, at lower temperatures than you're used to, and the margin between perfect and overdone is about 30 seconds. Salmon at 125°F (slightly translucent at the center) is perfect. At 145°F it becomes dry and flaky in the wrong way. Everything this week is about developing the instinct to pull fish early.

⏰ Planning Ahead

Service 21 (PROJECT: Whole Roasted Fish): buy a whole fish the same day for maximum freshness

Block 18 — Fish: Deeper Techniques & Global Preparations

Block 15–18 — Whole Fish & Curing

The central principle: Whole fish and cured fish are the two preparations that demand attention to the fish itself — its freshness, its age, its smell — in a way that a fillet from a vacuum pack never will. This week teaches you to read fish.

Optional: Go Deeper

These aren't required reading — but if something from this block sparked a question, here's where to go.

Buying Fish

The most important fish skill happens before you cook. Knowing what fresh fish looks and smells like — and what to ask a fishmonger — matters more than technique.

📖 How to Fillet a Whole Fish — The knife skill most home cooks never develop. Understanding the angle, pressure, and feel for running a blade along the spine changes how you approach any finned fish — whether you buy it whole or not.

The Bouillabaisse Deep Dive

Bouillabaisse is a lesson in building shellfish stock, saffron, and rouille — three techniques that extend into a dozen other recipes.

📖 Real Bouillabaisse (Bouillabaisse Marseillaise) — The full recipe and process: building the saffron-shellfish broth, making the rouille, and understanding why the dish is served in two stages. The technique is transferable to any rich shellfish stew.

Watching a Pro Do It

📺 Jacques Pépin fillets a fish — Watch the knife angle and the way he reads the bones. This is the hand skill that separates cooks who buy fillets from cooks who buy whole fish.
📺 Sole meunière in real time — Brown butter moves fast. Watching the color progression before attempting it is worth doing.

A Book Worth Having

📚 The Whole Fish Cookbook by Josh Niland — Argues for cooking the entire fish, reduces waste, and teaches you to see fish the way butchers see meat. Transformative for serious fish cooks.

⏰ Planning Ahead

Session 96 (Cioppino): ask your fishmonger 2 days ahead to save fish bones/shells for the stock

Advanced Seafood — Shellfish & Stews

"Shellfish are the most immediate form of the sea — they still smell like the ocean when they're alive, and they cook in minutes. Knowing how to handle them is knowing how to be present."

Session 94 — Mussels Marinière: The French Classic

Skill: Cooking shellfish in wine steam — the fastest impressive dish in this program. Two pounds of mussels, cleaned and debearded, cooked in white wine and aromatics for 6 minutes. The key: don't drown them in too much liquid. A thin layer of wine and aromatics in the bottom of the pot creates enough steam to open every shell.

📖 Read: BBC Good Food — Moules Marinière

Cleaning mussels: Pull off any beards right before cooking. Discard mussels that don't close when tapped sharply. Discard any that don't open after cooking.

Full Meal: Mussels marinière + grilled sourdough (the entire purpose is to soak up the cooking liquid) + Celery Root Remoulade (julienned celeriac in mustard-mayo dressing)

Component	Notes
Mussels	2 lbs per person; scrubbed, debearded right before cooking
Broth	1 cup dry white wine + 2 shallots + 3 garlic cloves + parsley stems
Bread	Grilled sourdough — functional here; the broth demands bread
Salad	Celery root remoulade — a classic French bistro side; mustardy, crunchy

Session 95 — Crab Cakes: Restraint Is the Technique

Skill: The test of a good crab cake is the ratio of crab to filler. Most crab cakes are bread cakes. A proper crab cake is barely held together — the crab is the thing, the binder is just enough to keep it cohesive.

📖 Read: Simply Recipes — Crab Cakes

Full Meal: Crab cakes + aioli or remoulade + Classic Coleslaw + quick-pickled red onion

Component	Notes
Crab cakes	85–90% crab; minimal binder (egg, mayo, small amount of panko)
Sauce	Aioli (Block 5–6 technique) or a simple remoulade
Side	Coleslaw — creamy, acidic counterpoint; the classic crab cake companion

Buying crabmeat: Fresh or pasteurized lump crabmeat is the practical choice. Pick through carefully for shell fragments before mixing.

⏰ Session 96 — Cioppino: The Italian-American Fish Stew

Skill: Building a great fish stew from a tomato-shellfish broth — the technique that integrates shellfish and fish at different add times based on their individual cook times.

📖 Read: Simply Recipes — Cioppino

Cioppino was invented by Italian immigrant fishermen in San Francisco — a tomato-and-wine stew into which firm fish goes first (10–12 minutes), then shellfish in order of cook time (clams and mussels first, shrimp last). The broth is the soul: deeply seasoned with fish bones and shellfish shells if you can get them.

Plan ahead: Ask your fishmonger 2 days ahead to save fish frames/bones — they're usually free. Simmer them in water with aromatics for 20 minutes = a quick fumet that transforms the broth.

Full Meal: Cioppino with fish, clams, mussels, and shrimp + Garlic-Rubbed Grilled Bread + Fennel and Orange Salad

Component	Notes
Broth	Tomato + white wine + fish stock/fumet + saffron (optional)
Fish (first in)	Firm white fish — cod, halibut (10–12 min)
Shellfish (last)	Clams, mussels (6–8 min), shrimp (2–3 min)
Bread	Thick slices of sourdough, garlic-rubbed and grilled
Salad	Fennel and orange — bright, anise-scented; San Francisco cioppino's natural companion

🎥 Compare Notes: Bouillabaisse and How to Make Fish Stock (Helen Rennie) — The technique for building shellfish stock is identical; watch how she extracts maximum flavor from bones and shells before anything else goes into the pot.

Session 97 — Miso-Glazed Black Cod (or Salmon)

Skill: The Nobu preparation — white miso, mirin, sake, and sugar applied to black cod or salmon and left to cure overnight. The sugars in the miso caramelize under the broiler in 4 minutes.

📖 Read: Serious Eats — Miso-Glazed Salmon

Black cod (sablefish) is the traditional fish for this preparation — its high fat content handles the sweet glaze without drying out. Salmon is the more accessible substitute. Start the cure tonight or apply it two nights ahead.

Timing: Apply glaze → refrigerate 24–48 hrs → broil 4–5 minutes on one side only → done.

Full Meal: Miso-glazed cod or salmon + Serious Eats — Japanese Rice + Sesame Cucumber Salad (Sunomono) + wilted spinach with ponzu

Component	Notes
Fish	Black cod or salmon, miso-glazed and broiled
Starch	Japanese-style short-grain rice — stickier, sweeter; the right rice for this dish
Veg	Sunomono cucumber salad — rice vinegar, sesame, clean and cold
Greens	Spinach wilted with ponzu — 30 seconds, done

⏰ Service 24 — Seafood Feast

The challenge: A generous seafood dinner that pulls together everything from this block. This is the dinner you serve to impress — or eat alone on a Friday when you feel like celebrating.

Full Meal:

Starter: Mussels marinière (Session 94 technique) — a small portion to start, with garlic-rubbed bread
Main: Cioppino (Session 96 — a larger pot made the same evening, or made a day ahead and reheated, which makes it richer)
Side: Serious Eats — Creamy Polenta alongside the cioppino
Dessert: Whatever you feel like — this meal doesn't need more complexity

Skill targets: Clean mussel broth (not watery or muddy). Cioppino with distinct, properly-cooked fish and shellfish — nothing rubbery, nothing falling apart. The whole table smells like the sea.

Optional: Go Deeper

Whole Fish: Why the Bones Matter

A bone-in whole fish cooks more slowly and more evenly than a fillet — the bones conduct heat and protect the flesh from the outside temperature. Once you understand this, you reach for whole fish differently.

📖 How to Fillet a Whole Fish — The knife skill that makes buying whole fish practical.

Curing: Beyond Gravlax

Gravlax is the entry point. The same principle (salt draws moisture, concentrates flavor, transforms texture) applies throughout Block 19–22 (Pork & Charcuterie). Once you understand salt curing, you start to see it everywhere.

📖 BBC Good Food — Gravadlax — The full recipe, including the mustard-dill sauce that's traditional with it.

Cioppino vs. Bouillabaisse

Cioppino and bouillabaisse use almost identical technique but diverge in flavor profile: cioppino is tomato-forward (Italian-American), while bouillabaisse relies on saffron, fennel, and a Provençal rouille. Both teach building a shellfish broth. Once you've made one, the other follows logically.

📖 Serious Eats — Bouillabaisse Marseillaise — If cioppino has you curious about the French version.
