​The Flavor Brief​

A weekly letter about food, science, and why things taste the way they do

Hi Reader

I was in Washington, D.C. last week for a friend's wedding, and once the festivities were wrapped up, I found myself at a familiar spot, doing something I hadn't done in years.

I ordered a Maryland crab cake.

It was at Hank's Oyster Bar, a place I visited regularly when I lived in D.C., back when it was a neighborhood spot rather than a memory. The crab cake tasted exactly the same. That same familiar salty-sweet taste of celery and cayenne from Old Bay. That's the thing about food. It doesn't account for the years that have passed or the distance you've traveled.

I lived in D.C. for years before moving to Los Angeles 12 years ago. For a long time after I left, I missed it. The seasons. The monuments lit up at night. The days I spent working in the lab at Georgetown, the evenings when I went out with my friends, and the weekends I visited family in the burbs. There were years when I seriously considered moving back.

Walking through the city, I kept noticing the gap between what I remembered and what was actually in front of me. The neighborhoods shifted. New restaurants where old ones used to be. I couldn't recognize U Street or the Wharf. This city clearly kept moving without me, which is exactly what cities are supposed to do.

But like D.C., I've changed, too. Most of my friends moved away. California grew on me in ways I didn't anticipate.

The crab cake, though. That was still there. Exactly as I remembered it.

I think that's what traveling back to a former home eventually teaches you. The place hasn't frozen in time waiting for your return. And honestly, neither have you. Los Angeles is home now in a way I didn't expect and couldn't have predicted when I first left. But there's something worth holding onto in the memories tied to food, the ones that bridge two versions of a life.

The crab cake did that for me last week. Sometimes that's enough.

On screen this week

AMERICA'S TEST KITCHEN Tandoori salmon on national television. This week, I'm joining Julia Collin Davison on ATK's flagship PBS show to make the first recipe I ever developed for the team. It's been a long time coming. (The link should switch to your local PBS station) Watch now on PBS →

THE RECIPE

EGG BHURJI/INDIAN-STYLE SCRAMBLED EGGS Egg bhurji is one of my all-time favorite ways to eat eggs, full stop. Garam masala, ginger, green chili, and a hit of ghee turn a simple skillet breakfast into something that makes you want to eat it heaped on buttered toast every single morning. Get the recipe →

SALMON TIKKA MASALA I know salmon tikka masala might sound slightly rogue, but stay with me. The salmon stays tender, the sauce is deeply savory and creamy. Serve it with rice, naan, or honestly just eat it like I do, standing over the stove with a spoon. Get the full recipe hosted at ATK Get the recipe →

THE SCIENCE EDIT

THIS WEEK'S PRINCIPLE

MARINATING FISH IS NOT MARINATING MEAT: WHY THE RULES CHANGE IN WATER.

Fish has a far more delicate muscle structure and higher water content than chicken or steak. That changes the chemistry of marinating, and it’s important to treat them differently or you'll wreck the fish every time.

Here's what's actually happening in that bowl, and how to make it work for you.

1. Acid "Cooks" Without Heat

The most important thing to understand is denaturation. High-acid ingredients like lemon juice, lime juice, or vinegar begin breaking down protein structures the moment they contact fish flesh.

The proteins unwind and coagulate, turning the flesh opaque and firm. That is exactly what heat does.

Leave fish in a high-acid marinade too long and it turns chalky and dry. For delicate white fish like tilapia or cod, stay between 15 to 30 minutes. A firm fish like swordfish or tuna is more forgiving and can handle up to an hour.

2. Marinades Flavor the Surface, Not the Center

Marinades don't soak deep into a thick fillet. Most flavor molecules are simply too large to penetrate more than a few millimeters past the surface.

Salt is an exception. Salt molecules are small enough to move into the muscle fibers via diffusion, and they carry moisture with them, which helps the fish stay juicy during cooking.

To get flavor deeper into the flesh, use a brine-based marinade or cut your fish into smaller pieces like kebab cubes to maximize the surface-area-to-volume ratio.

3. Raw Tropical Fruit Will Destroy the Texture

Certain raw fruits contain proteases, enzymes that digest protein aggressively.

• Pineapple contains bromelain
• Papaya contains papain
• Kiwi contains actinidin
• Passion fruit contains proteases
• Ginger, while not a fruit contains zingibain

In a marinade, these will flavor the fish but they will turn the exterior to mush. If you want that tropical character, use cooked or canned juice (heat destroys the enzymes) or add the raw fruit as a garnish after cooking. I heat it to a simmer over medium heat for 5 minutes and then let it cool completely before using.

4. Fat Carries the Aromatics

Many of the volatile compounds in herbs and spices are fat-soluble rather than water-soluble. The piperine in black pepper and the essential oils in thyme are two examples. Without fat in your marinade, those compounds stay suspended in the liquid rather than depositing onto the fish.

Including a quality oil like olive, avocado, or sesame gives those aromatics something to dissolve into. It also improves browning and heat transfer when the fish hits the pan.

5. The Cheat Sheet:

I marinate in the refrigerator, starting at the low end of the time range for new recipes or acidic marinades.

What I'M Loving

Özlem Warren's new cookbook, Istanbul (Amazon|Bookshop), will cost you an hour (or maybe more) you didn't plan to spend. Istanbul is one of the top destinations on my must-visit list, and she captures exactly what makes it so hard to leave, through the food, the neighborhoods, the layers of history on every plate. You will not be disappointed.

COMING UP

Fundamentals of Flavor is available for preorder now — this one has been six years in the making and I'm genuinely proud of it. If you've been cooking with me for a while, this book is for you. Preorder Now →

Thanks for reading, I hope something here makes it into your kitchen this week.
