The Flavor Brief

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

Hi Reader

Before I left for Boston last week, I spent all of Sunday cleaning my office.

I’d been putting it off for months. The large Monstera behind my chair finally got its leaves wiped down, stacks of notebooks were pushed into neat piles, camera cables went back into the old box they’ve lived in for years, and the exercise ball I temporarily moved into the house finally made its way back to the garage. I even unpacked my Jono Pandolfi teapot, which I picked up a few weeks ago at a sale, brewed a pot of tea, and let myself settle into the strange comfort of reorganizing small things.

This ritual matters more to me than it probably should.

I’ve learned that when my workspace falls apart, my brain usually follows soon after. The clutter slowly turns into noise. I get distracted more easily. Recipes stay unfinished. Emails sit unanswered. Little piles become large piles. Somewhere in the middle of it all, a quiet anxiety creeps in and starts asking if I’ve lost my ability to focus.

When I left research to work in food full-time, I imagined working from home would be liberating. From a creative standpoint it was, but often the days felt strangely quiet. I was in the kitchen with Snoopy, my beagle-boxer mix, tinkering with recipes while he watched me from the couch with what I’m now convinced was deep skepticism and bewilderment.

The blog forced me to teach myself food photography using a tiny Nikon Coolpix point-and-shoot camera. Most of the photos were terrible. Truly terrible! I did not know how to style food, work with light, or make anything look remotely appetizing. Sometimes I’d balance bowls on trash cans near the window and wait for the sun to cooperate. Other times I’d try photographing myself sifting flour into cake batter with a timer and sprint back into frame before the shutter clicked. Many a cake and frosting were sacrificed in the pursuit of photography.

Almost none of it was good.

But I loved the process of figuring it out.

I loved the quiet rhythm of testing recipes, adjusting spices, moving plates around the kitchen table, learning how ingredients changed their behavior entirely dependent on how they were treated, or why onions tasted sweeter after browning slowly. There was joy in the process because it felt like enough.

Back then, the internet felt smaller. Food blogs were like tiny neighborhoods where people exchanged stories and wrote their recipes. We weren’t chasing virality. We cooked something because we were curious or because we wanted to feed someone. Or because we wanted to introduce people to something new.

Things are much faster now. Recipes are content. Photos became videos. Everything is louder now and demands our immediate attention. And somewhere along the way, I think many of us quietly started measuring the value of our work by how loudly the internet responded to it.

This week, Flavor Forward was nominated for a James Beard Award in the Instructional Video category. I’ve been nominated twice before, once for Season in the Photography category and then for The Flavor Equation in the Reference, History, and Scholarship category. But this nomination feels especially meaningful because the show itself felt like an experiment from the beginning.

I’d never hosted a cooking show before. I would be lying if I didn’t say there was a bit of fear with this new undertaking. But someone wise once told me fear of failing can be a good thing — it means you care. What made the experience special was working with an incredibly thoughtful team that believed food science and curiosity could still feel warm, personal, and joyful. Somewhere between all the diagrams, spice jars, camera setups, and long filming days, we made something we’re genuinely proud of.

And while I’m incredibly grateful and honestly still processing it all, I keep reminiscing about those early days in the kitchen, with Snoopy watching me burn through batches of cake and take badly lit photographs. Back then, success looked much smaller. It was figuring out how to brown onions properly or finally taking one photo that didn’t look terrible. The joy came from the process itself, from slowly learning how to make something better than the day before.

That’s the part of creative work I’m still trying to hold onto. The part that’s curious and quiet. The part that falls in love with the process before worrying about the outcome.

This nomination means more to me than I can properly put into words. Mostly because it reminds me that all those quiet years of learning, experimenting, failing, and trying again mattered. And that somehow, through all the noise, the work still found its way to people.

In The Test Kitchen - Salads

This week’s episode of In The Test Kitchen starts with salad and spirals very quickly from there.

THE RECIPE

Yup, the theme the week is salads. It wasn't intentional but...

CABBAGE AND CHICKEN SALAD WITH CURRY LEAF VINAIGRETTE

A crunchy, flavor-packed salad with crisp cabbage and a bright curry leaf vinaigrette that might finally put those dreadful sad desk salads to rest.

SHAVED ASPARAGUS SALAD WITH CRISPY PROSCIUTTO

The asparagus in this salad is raw, and I promise that's a good thing. Crispy prosciutto, feta, cucumber, edamame, a lemon-coriander vinaigrette. Click the link. Make the salad.

THE SCIENCE EDIT

THIS WEEK'S PRINCIPLE

The "Steak-Fruit" Illusion: Why we char peaches.

Why does a grilled peach sometimes taste almost smoky or even faintly “meaty” despite being packed with sugar? The answer lies in a fascinating overlap between fruit chemistry, smoke, and heat-driven reactions.

1. The Molecules: Guaiacol and Lactones

Two important groups of aroma compounds are at work here.

The first is Guaiacol, a smoky phenolic molecule associated with smoked brisket, peaty Scotch, roasted coffee, and charred foods. It’s one of the compounds our brains strongly associate with “fire-cooked” flavor.

The second is lactones, especially gamma-decalactone, one of the compounds most responsible for the creamy, fruity aroma of peaches. As peaches heat up, these lactones become more volatile and pronounced, sometimes taking on richer, deeper, almost buttery qualities.

2. Heat, Smoke, and Plant Structure

Guaiacol is often produced during the thermal breakdown of lignin, the rigid structural material found in woody plant tissues. Peach flesh itself contains relatively little lignin, so the fruit contributes only a small amount directly. During grilling, a more important source is the smoke itself: combustion from wood or charcoal generates smoky phenolic compounds that settle onto the fruit’s surface.

When peaches hit intense heat from a grill or live fire, several things happen simultaneously:

  • sugars caramelize
  • Maillard reactions develop on the surface
  • the fruit chars slightly
  • smoky phenolic compounds from the fire deposit onto the peach
  • heat amplifies the fruit’s own lactones, making them smell richer and more buttery

Together, these reactions create aromas that overlap surprisingly well with roasted and smoked savory foods.

3. The “Savory Bridge”

This is why grilled peaches pair so naturally with pork, steak, prosciutto, or smoked foods. You’re creating shared aromatic notes between the fruit and the meat: smoke, bitterness, toastiness, caramelized depth, and buttery richness.

The peach still tastes sweet, but now it also carries many of the sensory cues we associate with barbecue and roasting.

Science Tip: Smoked Salt Shortcut

No grill? Smoked salt can approximate part of that fire-roasted effect. The smoky phenolic compounds absorbed into the salt during smoking contribute aromas similar to those deposited by grill smoke. The salt also draws moisture to the surface through osmosis, helping seasoning adhere more evenly.

It won’t fully replicate the intense surface chemistry of grilling, but it can create a convincing smoky illusion.

What I'm READING

A pile of new cookbooks have arrived, including The Great Book of Chocolate, Revised by David Lebovitz. This fully updated edition covers everything from the history of chocolate and bean-to-bar producers to his favorite chocolate shops in Paris, alongside more than fifty recipes — including fifteen new ones. It's the kind of book you read cover to cover and then bake from for years. A must for any baker and chocolate lover.

On May 12, I'll be in conversation with cookbook author Alana Kysar at Now Serving in Los Angeles about her new book; Aloha Veggies — a gorgeous, vegetable-forward celebration of Hawaiian cooking that's as delicious as it is beautiful. [EVENT DETAILS HERE]

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.

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