WASHINGTON (WASHINGTON POST) - Jeremiah Langhorne bends over a small coal bed in front of the log-stacked firebox in the kitchen at the Dabney restaurant.

As he fans them, the coals redden and shoot out sparks. The 540 deg C heat from deep within the firebox lashes out with angry blasts, but the chef's glasses don't fog, and his bearded face betrays only a light misting of sweat. He reaches in, barehanded, to spread some baby vegetables in a wire basket set on the coals, and keeps fanning.

"They'll stick at first, so we'll leave them alone for now," he says. "Wait for when they start to glisten."

What Langhorne is going for is a good char. Char, often confused with burn, is the dark edge on a cube of roasted butternut squash, that deep brown bubble on your pizza crust and the dark crosshatch marks on your perfectly grilled steak. Char is a trending flavour enhancer at restaurants and in processed foods, but home cooks often end up burning foods instead.

"A caramelised, paper-thin char layer gives you this smoke and wood flavour in the mouth, then suddenly disappears," explains chef Francis Mallmann. "Then the beauty of the flesh of the fruit or meat appears." His open-fire cooking inspired chefs worldwide when Mallmann was featured on the premiere season of the Netflix series Chef's Table.

"Imagine yourself going to a party," Mallmann says. "You dress very elegantly, and as you take a last glance in the mirror, you realise you are overdressed."

The difference between char and burn is "exactly the same type of thing. The line is so, so, so thin that you have to be very careful."

Food scientists agree that the line between char and burn is pretty fuzzy."The difference is in intensity, not in the type of process that is happening," says Bruno Xavier, processing authority at Cornell's Food Venture Center. Xavier explains that burning is a combustion reaction that requires oxygen. But, chemically speaking, char is formed by heating organic matter without the presence of oxygen, in a process known as pyrolysis. Meats, vegetables, even fruits can be charred (although medical experts warn that charred meats can be linked to cancer).

We don't cook in a vacuum, so getting a decent char in the kitchen is about good heat management even in the presence of oxygen. Think about the cut surface of an onion sitting in a cast-iron skillet, bathed in a steady heat transfer. A pan of carrots in the oven roasts in a closed environment, with no airflow. But an onion on a grill is sitting over open fire, feeding on oxygen, and quick to burn."It's a continuum, and absolutely a matter of personal taste," says Xavier. "Getting it right is about technique, patience, and trial and error."

Grillmasters everywhere aim for a good crust on grilled food, but it's actually harder to achieve char over charcoal. Even a pro like Mallmann sweats every detail of cooking over open flame."When I am cooking outdoors, I sit on a chair under a tree and look at the fire. Not for a second do I stop looking at what happens. You have to be very aware and alive and awake," Mallmann says. "It's a fragile thing, a feminine and beautiful thing to cook with fire. You need a lot of intuition." Fortunately, we have stove-tops and ovens, which are easier to manage. Charring anywhere, however, still requires lots of practise.

"It took us six months just to figure out how to use the wood-fired oven," says Frank Pinello, owner of Best Pizza in Brooklyn. Best Pizza serves Neapolitan-style pizza, of which char is an important element."Early on, we did a lot of testing," Pinello says. "We came up with a crust that has nice char marks, but sporadic. The bottom is evenly cooked, no black marks, that's what I like. If the oven deck is too hot, the bottom will get black. That's, to me, too much on the palate and stomach."

Here are pro tips for exploring the technique and figuring out where your own taste lies on the char-burn spectrum:

-Don't flame out. A stove-top or oven is a more stable environment than open flame for practicing with char. If you try fire, wait for the wood to burn into glowing coals. Then pull the coals to the side and cook directly over them. Use only coals that are fully red: Coals with black sections aren't ready yet; they're likely to flame up.

-Keep it dry. Although you can toss the food in a little oil, chefs recommend keeping the cooking surface dry. A dry surface can reach a higher temperature without smoking or burning a cooking oil. Oil on the surface of the food will quickly bond and cook along with the hot food, rather than smoking with the skillet or griddle. Chefs say cast iron is the best surface for getting the high heat you need for charring.

-Don't move the food around. Recipes have conditioned us to think that food needs to be cooked for an even time on each side, but this isn't true for developing char. Proper technique means leaving the food longer on the first side, letting it release its natural juices and develop a tasty crust. Resist the temptation to shake the pan or turn the food before it's ready. On "Chef's Table," Mallmann talks about cooking a steak for nine minutes: six on the first side to give it time to release, then three once you turn it.

-Wait for the sweat. So, when is that food ready to flip? Start checking it when it starts "sweating." As vegetables cook, they release their natural moisture. That moisture creates a barrier between the food and the cooking surface. The food will then release easily. If you find yourself prying food up with a spatula, it's not ready yet.

-Stay focused. Food can go from charred to burned in a heartbeat, so don't get distracted. Langhorne focuses fiercely on his coals, fanning, poking, adjusting. Even when he stands back to give the vegetables a rest, he stops mid-sentence the moment they need turning. "This is technique-related." he says. "You definitely have to practise with it." In front of the Dabney's massive soapstone hearth, Langhorne piles the charred vegetables over a scoop of farro salad to create one of the restaurant's signature small plates. The bite-size pieces of carrot, fennel, beans, peppers, okra and turnip have the occasional dark patch or browned edge, but overall they look glistening and tender.

A bite of baby bok choy showcases Langhorne's mastery of the technique. The vegetable still has an al dente heart, but the skin is soft and melting, with a deep, umami-rich infusion. It's only faintly, if at all, smoky. It's an ancient, earthy flavour that you desperately want more of. The dish disappears quickly.

"Right?" Langhorne nods enthusiastically. "That's char."

Charred Stone Fruit With Bay Leaf Cream

4 servings. You can also char the fruit over the direct heat of a hot grill for a few minutes, then move the fruit to the indirect-heat side of the grill and cook, covered, for about 10 minutes.

MAKE AHEAD: The infused bay cream can be refrigerated for 2 to 3 days in advance.


1 cup heavy cream

2 Tbs sugar

1 bay leaf

900g assorted stone fruits (nectarine, plum, peach), washed, halved and pitted

Flaky sea salt, for garnish (optional)

Extra-virgin olive oil, for garnish


1. Combine the cream, sugar and bay leaf over medium heat; as soon as the mixture starts to bubble at the edges, remove from heat. Cool to room temperature, then discard the bay leaf.

2. Wash the fruit, cut in half and remove the pits. Do not peel.

3. Heat a dry cast-iron skillet or grill pan on high heat. Place the halved fruit, cut sides down, on the hot surface. Cook for 3 to 5 minutes, until you see the fruit begin to release moisture. Lift carefully to check the char level - it should be dark brown, not black. Remove each piece as soon as it is done.

4. Meanwhile, pour the bay-infused cream into a mixing bowl; whisk just long enough to form soft peaks.

5. Arrange the fruit on a plate, cut sides up. Sprinkle fruit with a pinch of the flaky salt, if using, and drizzle with a small amount of oil. Add generous dollops of the softly whipped cream. Serve warm.

Hearth-Roasted Seasonal Vegetables

2 servings. Developing a good char is more about feel, and less about exact timing. Watch these vegetables closely for moisture and browning; the timing will depend on your coal bed.


1½ cups seasonal vegetables, cleaned and cut into bite-size pieces

2 Tbs garlic-flavoured oil, plus more for garnish

1 Tbs toasted/roasted sesame seeds

¼ tsp Aleppo pepper

Large lemon wedge

Kosher salt

About ¼ cup mix of soft fresh herbs and/or edible flowers, such as basil, mint, tarragon, thyme, marigold petals, nasturtium blossoms and borage flowers, for garnish

1. In a fire box, flat grill, or large, flat fire pit, build a hardwood fire. Let it burn until you have a good bed of all-red coals - you'll need a pile large enough to fit under a wire grilling basket.

2. Meanwhile, sort the vegetables into three piles: Firm root vegetables (carrot, parsnip, potato, winter squash, turnip); medium-firm (bok choy root, bell peppers, fennel, celery); and leafy greens (kale, chard, bok choy tops). In a medium-sized bowl, toss each set of vegetables with the olive oil; remove and set aside.

3. Rake the coals away from the fire into a small pile. Fan them to remove ash. Set a wire grilling basket atop the coals to preheat it (the wire will start to glow red in the center). Add the firm vegetables, spreading them evenly in the basket

4. Watch the vegetables closely, fanning the coals occasionally, until they begin to release moisture. Remove the basket and turn the vegetables with tongs, checking for tenderness and browning.

5. Before they are done, slide the firmer vegetables to the side of the basket, and add the medium-firm vegetables, spreading them out. Fan the coals occasionally and watch for them to release moisture. When they begin to sweat, turn them and add the leafy greens.

6. Briefly cook the leafy vegetables (some will darken and turn crisp). When they are wilted, remove the basket from the coals.

7. Toss the vegetables with a splash more olive oil, freshly squeezed lemon juice, sesame seeds, Aleppo pepper, and salt to taste. Garnish with fresh herbs. Serve warm.

Roasted Carrots With Thyme and Rosemary

8 servings. The char on these roasted carrots adds a deep umami richness to a classic side dish. Resist the urge to stir; instead, let them build patches of dark caramelisation.


3 Tbs olive oil

1.8kg carrots, scrubbed well and cut into bite-size pieces

2 Tbs unsalted butter

1 tsp kosher salt

½ tsp freshly ground black pepper

1 Tbs fresh thyme leaves

1 Tbs fresh rosemary, chopped


1. Preheat the oven to 190 deg C.

2. Heat a large, ovenproof saute pan over medium-high heat. Add the oil and swirl to coat.

3. Add the carrots, spreading them evenly, but do not stir. Cook for several minutes, stirring only once after you see the carrots begin to release moisture. A few minutes later stir again, looking for good caramelisation on the carrots.

4. Add the butter, salt, pepper, thyme and rosemary. Toss to incorporate; cook for 1 to 2 minutes - just long enough to blend the flavours.

5. Transfer the pan to the oven; roast for about 25 minutes, until the carrots are tender.

6. Serve hot, or at room temperature.
