The benefits of sous vide: cooking food in bags immersed in water

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.

How freeze-drying leaves food with less than 4% of its original water content

In specialized equipment, foods are brought down to temperatures below freezing before a vacuum pump removes the air from the container, lowering the pressure around the food and the boiling temperature of water. Heaters beneath the food slowly raise its temperature above the now-reduced boiling point, causing the water to go from a frozen to a gaseous state.

Learn how air fryers cook food without the use of oils

While deep or pan frying involves oil transferring thermal energy to the food, air fryers warm food through constant airflow, which prevents the formation of a boundary layer of cold air around the food, though air is a worse conductor of heat.

How to cook food with lasers

Creative Machines Lab at Columbia Engineering have developed a system of software-controlled lasers to cook food with precision, retain moisture with the final-cooked product, brown food within its original packaging, and create an entirely new meal creation process for a consumer. Watch this three-minute video to see for yourself.

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.

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.

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.

How Michelin-starred chefs cook steak

Earning a Michelin star is no easy feat; neither is cooking a steak. This tutorial, featuring three Michelin-starred chefs, shows how the pros tackle the subtle art, walking even the most kitchen-averse eaters through the best ways to cook a great cut.

How the methods of catching fish for food affects their taste

Commercially caught fish are often killed through suffocation, allowing the causing the fish extreme stress and flooding their bodies with stress hormones and lactic acid. These chemicals cause the fish's flesh to become bitter where it was once rich and quickens the rotting process.

Gas station sushi is actually pretty safe to eat, experts say

Vending machine food, in general, gets a bad rap for its seeming lack of freshness, but whether the food you eat is safe usually depends on the quality of the cold chain supply logistics that brought it to the point of sale. Most prepackaged sushi fish has been flash frozen, and the rice has been mixed with vinegar to inhibit bacteria.

The microplane zester, mortar and pestle, and other underrated kitchen tools

Eight chefs weigh in on the most helpful culinary tools they often don't see in people's kitchens. The very specific fish fork, for example, not only delicately moves fragile filets but can double as an olive or soft cheese server.

Can fasting help you live longer?

Animal studies into the health benefits of calorie restrictions of 20%-40% suggest it extends life spans and reduces incidents of age-related diseases, including cancer. This article explores the research into fasting, calorie restriction, and longevity.

How to create salad dressings with oil and water solutions that don't separate into layers

Such dressings, even when whisked together, often break within a few minutes, resulting in bites that are either harsh or oily. Small amounts of emulsifiers, such as mustard or mayonnaise, can stabilize and suspend oil droplets in water for longer periods because they possess both hydrophilic (water-loving) and hydrophobic (water-repelling) ends.

How spoiled meat helped uncover a bacterium that can survive the vacuum of space

When a can of ground beef and pork spoiled despite attempts to sterilize it with gamma radiation, researcher Arthur Anderson isolated the bacteria in the food and discovered Deinococcus radiodurans. The polyextremophile has since been found on the walls of nuclear reactors and overcomes radiation damage through highly optimized DNA repair mechanisms.

'This is my invariable advice to people: Learn how to cook—try new recipes, learn from your mistakes, be fearless and above all have fun.'

Slow pour-over coffee resists the haste of 'espresso' and commodification of drip

Pour-over coffee involves what its name suggests: slowly pouring hot water from a gooseneck kettle over a funnel of ground coffee, usually requiring at least 3 minutes. This trend developed in the 1970s in opposition to on-demand drip coffee and "espresso," literally invented as an "express" option to save time.

Ultraprocessed foods include preservatives, dyes, sweeteners, and more

Processed foods are those that have been altered from their original state, which includes numerous processes that we consider natural, such as cooking or salting. Ultraprocessed foods contain at least one item that wouldn’t be found in a kitchen, like hydrogenated oils or high-fructose corn syrup. It’s estimated that nearly 75% of all foods consumed in the US are ultraprocessed, though that doesn’t mean that all of them are unhealthy. In fact, some, such as prepackaged whole wheat bread and soy milk, are recognized for their health benefits.

The history of many kitchen appliances involves unexpected discoveries and applications, including wartime radar turned hamster defroster and replacing an 'ice king' with heat-stealing boxes.

Sand 'batteries' can store excess electricity from the power grid as thermal energy

Energy collected from solar or wind power is used to heat insulated silos full of sand to temperatures as high as 450 degrees Celsius (842 degrees Fahrenheit), which can be retained for long periods. These thermal energy storage systems can be designed to boil water and generate electricity when needed.

Research studies can be conducted inside or outside of living samples

While "in vitro" experiments occur outside living organisms for cost-effectiveness, "in vivo" experiments take place inside them, providing real-life insights at a higher cost and with increased ethical concerns. Alternatively, "in silico" methods use computational simulations.
