Barbecue relies on a unique scientific equation

Barbecue can be made with direct or indirect heat

Direct heat, called “grilling” in the USA, involves quickly cooking ingredients directly over the heat source. It's usually used for hamburgers or Japanese yakitori skewers. Indirect heat, where the ingredients are placed adjacent to the flames to cook “low and slow,” is associated with American barbecue dishes like smoked brisket.

Barbecue is a cooking style practiced across the globe

How many ways are there to cook meat over a fire? Tons, it turns out. Every continent, barring Antarctica, has a local version (or versions) of barbecue. For instance, in Japan, it’s meat-laden skewers cooked over Japanese oak charcoal. Head down to Argentina, and you’ll find parillas—open-flame grills that impart a smoky char to the ingredients.

American barbecue varies by region, with particularly strong traditions in the 'barbecue belt' of Texas, Memphis, Kansas City, and the Carolinas.

Kansas City barbecue makes use of 'burnt ends'

The Midwest city has its own delicious tradition, serving the double-smoked chunks of fatty brisket slathered in the region’s signature thick, sweet-and-spicy sauce.

The food took root with Black Americans in the Civil War era

Because the technique requires little equipment and can tenderize tough or undesirable cuts of meat like ribs, barbecue took root among impoverished Black Americans in the late 1800s. When these communities moved north during the Great Migration, barbecue followed.

The preferred barbecue sauce depends on your location

America's regional barbecue styles include multiple highly specific sauces. From the tart, acidic vinegar-based sauces of North Carolina, to the thick, sweet-spicy Kansas City variation, American barbecue sauces are as varied as the country’s geography.

The word 'barbecue' is thought to come from 'barbicu'

Modern barbecue originated in the precolonial Caribbean and Americas. The word is thought to come from the Indigenous term for wooden frames used to cook meat high above the fire.

Cookout and barbecue culture boomed in post-war 1950s America

Magazines like "Life" fueled the outdoor cooking craze, and by 1955, barbecue had grown into a $100 million industry. American Studies scholar Kristin L. Matthews explains that the trend fit neatly with Cold War-era consumerism and the emphasis on home ownership.

Memphis-style barbecue emphasizes pork

The cuisine's signature dish is dry-rubbed ribs. Before smoking, the meat gets a spice rub with paprika and chili powder. Some restaurants also offer their ribs “wet” (with sauce) or “muddy” (a mixture of sauce and rub).

Americans' love of combining freedom and charred meat began in the 1800s

In the 19th century, politicians (particularly in Virginia) hosted large public barbecues to celebrate Independence Day and, of course, boost their own campaigns. When personal grills became common in the 20th century, the tradition moved into backyards and block parties, where it's still going strong today.

Kansas City is home to the first museum of barbecue

America is home to several kinds of barbecue, leading one Kansas City food writer to open the world's first museum dedicated to the cuisine. The Museum of BBQ tells the story of the food's evolution through interactive exhibits, a sauce immersion room, and even a barbecue-themed playground.

Korean barbecue uses thin slices of marinated beef

The history of molecular gastronomy, from thickening yolks with alcohol to making art with food

Before understanding why they worked, humans used scientific principles, including designing solutions and analyzing outcomes, to develop preservation methods like curing meat and fermenting vegetables. By the 20th century, the application of industrialized food preparation to smaller kitchens set the stage for the subdiscipline of food science.

'Braai' is South Africa's take on barbecue

Braai—a colloquialism for the Afrikaner word for “grilled meat”—is a South African tradition similar to American cookouts, where communities gather to cook meat over a wood fire.

Spanish conquistadors encountered barbecue in the 16th century and called it 'barbacoa.'

Watch an animation of what happens inside cookies as they bake in an oven

As temperatures rise and butter melts, trapped water expands, spreading the dough, which remains held together by a network of proteins. Maillard reactions produce browning on the surface beyond 310 degrees Fahrenheit (154 degrees Celsius), while caramelization can be triggered by baking past 356 degrees Fahrenheit (180 degrees Celsius).

Pellet grills evenly distribute heat across a grill

Using ignited wooden pellets and fans to evenly distribute the heat across the cooking surface, pellet grills give food deep flavor and grant cooks more control, offering a newfangled take on barbecue.

Low-and-slow smoking transforms tough cuts into tender, flavorful cuisine

Cooking meats at low temperatures over many hours breaks down muscle proteins and collagen into gelatin, making the meat juicy and soft. Patience, gentle smoke, and moisture retention are needed to avoid dry or chewy results.

What makes food crispy, and how science can be used to maximize this property

The fracturing texture experienced when biting into vegetable tempura, fried chicken, pastry crusts, and other foods comes from having a dehydrated, porous surface. When frying food in hot oil, trapped water vaporizes and escapes, creating tunnels and pores in the food as it dehydrates. Breading, particularly with the large, irregular shapes of panko, and leaveners can help create more air spaces.

George Washington was a fan of barbecue

The first US president celebrated laying the cornerstone of the US Capitol by hosting a barbecue, the centerpiece of which was a 500-pound ox. By the 19th century, barbecue was a standard component of public celebrations, including Independence Day and Memorial Day.

Fireworks' chemical composition and internal layout produce their unique displays

The burning of different metal compounds, facilitated by combining fuel with oxidizers, results in explosions of varying colors. The timing and pattern are engineered through the arrangement of pellets and fuses.

How science came to understand umami

Before Dr. Kikunae Ikeda sat down in 1907 and pondered the taste of dashi, scientists typically agreed upon four types of taste: sweet, salty, bitter, and sour. He boiled 90 pounds of kelp into a resin that he then stripped of different compounds until he was left with a single ounce of brown crystals. Testing later revealed these crystals were glutamate, an amino acid and one of the protein's building blocks.

The research that led to sour

Scientists are trying to figure out if there are unique receptors that respond to the molecules that make up flavors we associate with calcium, blood, batteries, and other items that often escape dinner menus. Taste researcher Dr. Danielle Reed says the minimum evidence for a taste category typically involves identifying dedicated receptors and then removing them to show the taste vanishes.

Explore a list of 12 recipes incorporating techniques from molecular gastronomy

The recipes include popcorn shooters that taste like liquid caramel corn, almost-instant soft serve made by blending frozen fruit with sugar and fromage blanc, a fusion of fried rice and pizza, and skewered fruit coated in a broiled, glossy meringue.

The importance of volatile aroma compounds in the flavor quality of food

Processes such as air movement and heating cause food to lose aroma molecules, which studies have shown play a major role in our sense of taste. While losing these molecules to the environment leaves fewer to be processed during consumption to intensify flavor, it can also produce previously nonexistent aroma compounds or release previously trapped ones, altering or enhancing the food's flavor.

Spontaneous combustion involves an object igniting on its own

Even without matches, sparks, or external flames, exothermic chemical or biological reactions can increase the internal temperature of objects to the point where they reach a threshold temperature that can cause them to catch fire. Running batteries and fermenting bacteria within compressed materials can build this heat and cause combustion.

Explaining why salt should be used to season food early in the cooking process

Experiments involving the same dishes, with salt added at the start of cooking versus at the end, have been shown to yield drastically different taste outcomes because salt takes time to diffuse into foods, particularly vegetables, whose cells are surrounded by cellular membranes and walls. Salting at the end will produce a concentrated surface coating, rather than even seasoning.

Microwave ovens heat food by agitating certain molecules with non-ionizing light

Molecules with resonant frequencies within the microwave range vibrate, producing heat between adjacent matter, just as hands warm when rubbed together. The mesh in front of an oven's door confines the microwaves to the container, while the rotating plate allows different parts of food to travel through regions of maximum vibration.

How texture affects taste

Texture is the brain's interpretation of several sensations, including pressure, as registered by our teeth, tongue, and finger tips, and sound, as recorded by our ears. Texture also speaks to food particle sizes—smaller than 35 microns contributes to the sensation of creamy—and the balance between flavor and mouth time, such as the crunch of a crispy chip or the bounce of a chewy caramel.

The 'drinks' included cocktails in the form of alcohol-infused sugarcanes, a cotton candy piña colada, and a dual-textured, temperature-changing gin fizz. Foods included a gorgonzola cheese sphere with the consistency of a chocolate egg and a dish of freeze-dried and foam tofu with the appearance and texture of tiramisu.

The origin of the term 'molecular gastronomy' and its first international workshop

The 1992 event was born from a conversation between American cooking instructor Elizabeth Cawdry Thomas and Italian physicist Ugo Valdrè, who agreed on the merits of the science of cooking. The International Workshop on Molecular and Physical Gastronomy was named, in part, after the field of molecular biology to lend it prestige and greater seriousness.

Understanding the biochemistry of ingredients and taste can improve flavor and texture

Keeping eggs at room temperature produces smoother batters when baking, and doing the same with tomatoes helps prevent a mealy, granular mouthfeel. Salting meat a day before gives more time for proteins to break down, improving flavor and tenderness, while cooking vegetables in well-salted water can lock in nutrients and color.

Our sense of smell affects what foods taste like and how we perceive it

Scent stimulates our olfactory sensor neurons high in the nasal cavity, and the brain attaches labels to those scents. But when we eat, chemicals from the foods travel from our mouths and throat to those neurons. We have roughly 400 odor receptors, and they can be used to decipher more than 10,000 different odors (or more than one trillion by some calculations), including the nuances of different foods.

Learn the history of food science breakthroughs from the 20th century

Long after humans developed the means to produce sufficient food to feed civilizations, scientific research focused on a wide variety of objectives, such as developing methods to preserve food quality (accomplished via frozen food), speeding up cooking (leading to the microwave), and lowering the cost of sweetening food, which high fructose corn syrup provides.

Miracle berries make things that normally taste acidic or sour, such as lemons, taste sweet, like sugar-coated candy, by binding a special protein called miraculin to taste buds.

Although vinegar was first discovered when wine was left to sour after exposure to air, the fermentation of different base ingredients contributes to the variety of vinegars seen today.
