Brining
Brining: preserving, seasoning, and tenderizing food with brine or coarse salt.
Last updated
Brining is a technique for treating food with either a saltwater solution or dry coarse salt, serving to preserve, season, and improve tenderness. While the basic process relies on salt, additional ingredients such as herbs, spices, sugar, caramel, or vinegar can be introduced to deepen the flavor profile. The duration of brining varies significantly by food type: meat and fish are typically brined for less than twenty-four hours, whereas vegetables, cheeses, and fruit undergo a much longer process known as pickling. Brining is distinct from marination, as marinades generally contain a substantial amount of acid like vinegar or citrus juice.
Dry brining
It also differs from curing, which primarily involves the application of salt (and often nitrates/nitrites) to preserve food; while drying may accompany curing, it is not a defining requirement. For meat, brining involves soaking it in a seasoned saltwater solution before cooking, with times ranging from thirty minutes to several days depending on the cut’s size and thickness. An alternative method, dry brining, coats the meat in coarse salt and lets it rest; the salt draws moisture from the interior to the surface, where it mixes with the salt and is then reabsorbed, effectively brining the meat in its own juices. The salt rub is then rinsed off and discarded before cooking.
Food scientists debate two theories for brining’s effect. One holds that salt ions diffuse into cells due to higher brine salinity, while cell solutes cannot escape, causing the cells to absorb water via osmosis. The other suggests that salt denatures proteins, causing them to coagulate into a matrix that traps water during cooking, preventing dehydration.
Fish
In fish preparation, wet-salting involves immersion in brine rather than dry salting. For long-term preservation, the brine must contain at least 20% salt—a process called heavy salting—and the fish must be desalted in cold water or milk before consumption. Lighter salt levels suit immediate consumption but require refrigeration. Wet-salting is used for salted herring (heavily salted with 20% brine), soused herring (lightly salted at 2–3%), anchovies (which may liquefy after years for paste), and caviar.

Lore & Background
Food scientists have two theories about the brining effect, but which one is correct is still under debate. The brine surrounding the cells has a higher concentration of salt than the fluid within the cells, but the cell fluid has a higher concentration of other solutes. This leads salt ions to diffuse into the cell, while the solutes in the cells cannot diffuse through the cell membranes into the brine. The increased salinity of the cell fluid causes the cell to absorb water from the brine via osmosis.
The salt introduced into the cell denatures its proteins. The proteins coagulate, forming a matrix that traps water molecules and holds them during cooking. This prevents the meat from dehydrating.
Reader's Guide
Meat: Brining is a food processing technique in which meat is soaked in a salt water solution – a brine – similar to marination before cooking. The brine may be seasoned with spices and herbs. Duration varies from 30 minutes to several days depending on the cut's size, thickness, and desired effect. Dry brining: Brining can also be achieved by covering the meat in dry coarse salt and left to rest for several hours.
The salt draws moisture from the interior of the meat to the surface, where it mixes with the salt and is then reabsorbed with the salt essentially brining the meat in its own juices. Fish: As opposed to dry salting, fish brining or wet-salting is performed by immersion of fish into brine, or just sprinkling it with salt without draining the moisture. To ensure long-term preservation, the solution has to contain at least 20% of salt, a process called 'heavy salting' in fisheries; heavy-salted fish must be desalted in cold water or milk before consumption. If less salt is used, the fish is suited for immediate consumption, but additional refrigeration is necessary for longer preservation.
Vegetables
Wet-salting is used for preparation of: salted herring, non-gutted, with hard or soft roe and heavily salted (20% NaCl brine, with final product containing around 12% salt); soused herring which is gutted and lightly salted (2–3% NaCl), without roe; anchovies, which can be immersed in brine or wet-salted. After several years, the fish liquefies and can be processed into paste or anchovy butter; caviar and other types of roe. Vegetables: Vegetables are immersed in brine, vinegar or vinaigrette for extended periods of time in the process of pickling, where they undergo anaerobic fermentation which affects their texture and flavor.
Pickling can preserve perishable foods for months. Antimicrobial herbs and spices, such as mustard seed, garlic, cinnamon or cloves, are often added. Unlike the canning process, pickling (which includes fermentation) does not require that the food be completely sterile before it is sealed. The acidity or salinity of the solution, the temperature of fermentation, and the exclusion of oxygen determine which microorganisms dominate, and determine the flavor of the end product.
