Brining

Lore & Background

Brining is similar to marination, but a marinade usually includes a significant amount of acid such as vinegar or citrus juice. It is also similar to curing, which involves significantly drying the food over a much longer time period. For meat, brining duration varies from 30 minutes to several days depending on cut size, thickness, and desired effect. Dry brining involves covering meat in dry coarse salt, which draws moisture from the interior to the surface, where it mixes with the salt and is then reabsorbed, essentially brining the meat in its own juices; the salt rub is rinsed off before cooking.

Brining is significant as a versatile method for enhancing food texture and flavor while extending shelf life. Food scientists have two theories about the brining effect, but which one is correct is still under debate. One theory holds that salt ions diffuse into cells, causing water absorption via osmosis. The other theory states that salt denatures proteins, which coagulate and trap water molecules during cooking, preventing dehydration. For fish, wet-salting with at least 20% salt ensures long-term preservation, while lighter salting requires refrigeration. Vegetables undergo anaerobic fermentation in brine or vinegar during pickling, which can preserve perishable foods for months. Brine is also used in cheese production for brined cheeses like halloumi and feta, and for washed-rind cheeses like Munster.

• Brining can be achieved by covering meat in dry coarse salt, which draws moisture from the interior and reabsorbs it with salt.
• Food scientists have two theories about the brining effect, but which one is correct is still under debate.
• Heavy-salted fish must be desalted in cold water or milk before consumption.
• Pickling can preserve perishable foods for months without requiring complete sterility before sealing.
