Technique:salt as a chef's tool for flavour and texture
Salt denatures muscle proteins so they retain more moisture during cooking: wet brining increases the moisture capacity of poultry by 15\u201325% (Modernist Cuisine, 2011). Juicier meat for the same cost price.
In brief
Brining is the treatment of meat or fish with a salt solution (wet brining) or dry salt mixture (dry brining) before cooking. Salt denatures muscle proteins and increases their capacity to retain moisture, resulting in a juicier end product. Additional benefit: salt on the surface dries the skin for a crispier crust.
- Wet brining: 5\u20138% NaCl in water, 12\u201324 hours for poultry, 30\u201360 min for fish (CIA, 2011)
- Dry brining: 0.5\u20132% salt on the surface, 1\u201324 hours depending on thickness (L\u00f3pez-Alt, 2015)
- Mechanism: osmosis + protein denaturation increases moisture capacity by 15\u201325% (Modernist Cuisine, 2011)
- Side effect: surface moisture evaporates after brining, skin dries: ideal for crispy roasting (McGee, 2004)
Wet brining vs. dry brining
Wet brining: 5\u20138% NaCl solution
Wet brining: dissolve salt in cold water (5\u20138% = 50\u201380 g salt per litre), optionally add sugar, herbs and spices and fully submerge the product. Modernist Cuisine (2011): wet brining increases the moisture retention of poultry by 15\u201325%. CIA (2011): always brine in the refrigerator at 4\u00a0\u00b0C, never at room temperature. Brine temperature is critical: bacterial growth in warm brine is a hazard. After brining: rinse and pat dry before cooking.
Dry brining: superior for crispy skin
Dry brining: sprinkle the product with 0.5\u20132% of its weight in salt (e.g. 10 g salt per 1 kg chicken). Rub into the surface, including under the skin for poultry. Place uncovered on a rack in the refrigerator for 1\u201324 hours. L\u00f3pez-Alt (The Food Lab, 2015): the first hours, salt draws moisture from the product (osmosis); afterwards the surface reabsorbs this salty moisture. The result: deeply penetrated salt and a dry surface for crispy roasting.
Fish brining: salmon and other oily fish
Brining fish for smoking or cooking: wet brining salmon for 30\u201360 min in a 10% brine (100 g salt per litre) produces the classic gravlax texture. Dry brining salmon: 2\u20134% salt on the surface, 30\u201360 min, then rinse before smoking. McGee (2004): salt draws moisture from the fish tissue (dehydration), firms the texture and extends shelf life by lowering water activity. For gravlax, sugar (1:1 with salt) and dill are also added.

The science of brining
Osmosis and moisture retention
Osmosis: water moves from low to high salt concentration. During wet brining, salt water enters the cell via osmosis, but also partly exits (if the brine concentration is high). The net effect at the correct brine concentration (5\u20138%): salt denatures myosin proteins, which form a looser network and hold more water. Modernist Cuisine (2011): 15\u201325% more moisture in cooked poultry after wet brining.
Salt and protein structure
Salt (NaCl) dissociates into Na+ and Cl- ions that bind to muscle proteins. This disrupts the intermolecular bonds of myosin, loosening the protein structure and creating more space for water. McGee (2004): this is the same chemistry as brining for preservation, but at a lower concentration range for cooking.
Dry brining: the osmotic cycle
L\u00f3pez-Alt (2015) describes the 3-phase cycle: (1) First 30 min: salt draws moisture from the product (osmosis), surface becomes wet. (2) 30\u201360 min: salt dissolves in the moisture, forming a concentrated salt solution on the surface. (3) After 60 min: this salty liquid is reabsorbed through diffusion, penetrating deeper into the meat. After 12\u201324 hours the surface is dry: ideal for crispy roasting.
Step-by-step method
-
1
Calculate the salt dosage
Weigh the chicken: 1.5 kg chicken = 22.5 g salt (1.5% of body weight). Use non-iodised table salt. Optional: add 0.5% sugar, black pepper and paprika for flavour.
-
2
Apply salt to the surface
Sprinkle the salt evenly over the entire surface, including the cavity of the chicken. Work the salt under the breast skin with your fingers. Even distribution is essential.
-
3
Place on a rack in the refrigerator
Place the chicken on a rack above a tray (to catch any liquid) in the refrigerator. Uncovered: air circulation around the chicken dries the surface. 4\u00a0\u00b0C is mandatory.
-
4
Wait 12\u201324 hours
Minimum 4 hours for a noticeable effect, optimal 12\u201324 hours. After 1\u20132 hours you will see moisture on the surface: this is the osmotic phase. After 12 hours the surface is dry: the salt has been reabsorbed.
-
5
Cook without rinsing
With dry brining: DO NOT rinse before cooking. The salt has already penetrated deep into the meat. Pat the surface dry with kitchen paper and cook directly. Result: crispy, golden skin.
HACCP and food safety during brining
Brining exclusively in the refrigerator
Brining at room temperature is prohibited in the professional kitchen. Brine solution above 8\u00a0\u00b0C creates ideal conditions for Salmonella and Campylobacter. NVWA: always handle raw poultry at 4\u00a0\u00b0C. Use a chilled container or cold ice beneath the brine container if refrigerator capacity is insufficient.
Never reuse spent brine
Spent brine (from wet brining) contains proteins, blood and potential pathogens from the raw product. Discard immediately after use. Never reuse for a subsequent batch, even if the brine looks clean. CIA (2011): spent brine is a microbiological hazard.
\u23f1 Over-brining: texture damage
Wet brining for longer than 24 hours at high concentrations damages the muscle proteins excessively: the meat becomes mushy and loses its texture. Dry brining for more than 48 hours produces an overly salty taste. Monitor brining times with a timer.

Food cost and brining
- Moisture retention: 15\u201325% more moisture in the end product means more usable weight per purchased kilogram
- Waste reduction: less dehydration during cooking = less portion weight loss = more portions per kilogram purchased
- Cost-efficient: salt is one of the cheapest ingredients: brining a chicken costs less than \u20ac0.05 in salt
- Quality perception: brined chicken with crispy skin justifies a higher menu price
