🧂 Block 9–10: Seasoning & Flavor Building

← Block 7–8: Stocks & Eggs | Block 11–12: Vegetables →

Where we are: Knife skills done. Heat methods done. Mother sauces done. Stocks and eggs done. Now we go deeper — into the invisible architecture of flavor itself.

"Salt makes food taste more like itself. Acid makes it taste more alive. Fat makes it taste more satisfying. Understanding all three changes everything."

The core idea for these two weeks: Most home cooks season once, at the end, with a generic shake of salt and pepper. Professional cooks season in layers — each component seasoned individually, each layer building on the last. By the end of Block 10, you should never walk away from a dish thinking "something's missing" without knowing exactly what that something is.

Before you start Block 9, read these two pieces back to back:

Block 9 — Salt: When, What, and Why

The lesson: salt behaves differently at different stages of cooking, and learning to recognize what your food is missing — flat? dull? one-dimensional? — is more valuable than any single technique.

The Block 9 experiment (do this before the block starts): Take a carrot. Cut it in two. Salt one half with a pinch of kosher salt and wait two minutes. Taste both back to back. The salted carrot will taste more carrot-y — brighter, sweeter, more itself. That's the point. Salt doesn't make food taste salty. It makes food taste like food.

⏰ Planning Ahead

  • Session 34 (Brined Chicken Thighs): dry-brine the night before your first session
  • Service 10 (Miso-Glazed Cod Project): apply miso marinade 24–48 hrs ahead; start two days before

Block 10 — Acid, Fat, and the Fifth Taste

The lesson: seasoning is not just salt. Acid brightens. Fat carries and extends. Umami deepens. Knowing which one is missing from a flat dish is the difference between following a recipe and actually cooking.

Optional: Go Deeper

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

Salt: When to Add It and Why It Matters

The single biggest improvement most home cooks can make is learning to salt earlier and more confidently. The science backs it up.

Spice Blends & Marinades: Seasoning with Depth

Spice blends are dry-rub seasoning applied before cooking — essentially a flavored version of the dry-brining technique from Session 34. Marinades are liquid equivalents (acid + fat + spice) that season the surface and, over longer contact time, begin to alter texture.

  • 📖 Serious Eats — Garam Masala — How to build a spice blend from scratch: toasting whole spices, grinding, balancing. The principle transfers to every spice blend (ras el hanout, za’atar, Chinese five-spice). Once you've made one from scratch, you understand all of them.
  • 📖 Serious Eats — Chimichurri — The herbaceous Argentine marinade/sauce; a model for understanding how acid (vinegar), fat (oil), and a punch of fresh herb work together as a marinade or a finishing sauce.

Acid: The Underused Seasoning

Salt gets all the attention, but acid is what makes a dish taste complete. A squeeze of lemon or a splash of vinegar at the end is often all a dish needs.

Watching a Pro Do It

  • 📺 Samin Nosrat's Salt Fat Acid Heat — Four episodes, each focused on one of this week's themes. Her episode on salt is the best explanation of when and how to salt that exists on screen.

A Book Worth Having

  • 📚 Salt Fat Acid Heat by Samin Nosrat — This week's curriculum in book form, written for exactly the stage you're at. Possibly the best cooking book of the last ten years for developing instinct rather than just technique.
  • 📚 On Food and Cooking by Harold McGee — Ch. 8 (Flavorings from Plants) covers salt's effect on protein, how acids brighten flavor, and capsaicin chemistry. Ch. 11 (Sauces) on flavor compound interactions. Full reading guide →
