Marinate

Marinating is the process of soaking or coating food in a seasoned liquid or paste before cooking. A marinade may add flavour, change surface texture and, in some cases, help tenderize the exterior of the food. Its effect depends on the ingredients, concentration, time, temperature and structure of the product. Most marinades do not penetrate deeply into thick pieces of meat.

Common types of marinade

• Oil-based: oil carries fat-soluble aromas from herbs, spices and aromatics.
• Acid-based: citrus juice, vinegar or wine changes the surface proteins and can create a firmer or softer texture depending on the food and exposure.
• Dairy-based: yogurt or buttermilk can add flavour and help tenderize the surface of meat or poultry.
• Dry marinade: a mixture of salt, spices, herbs and other dry ingredients applied directly to the food.

How long should food marinate?

Marinating time depends on the ingredient and the marinade. Delicate fish may need only a short exposure, while larger pieces of meat may benefit from several hours under refrigeration. Excessive exposure to strong acids can make the surface of fish or meat mushy or denatured. Always marinate potentially hazardous foods in refrigeration.

Marinating versus brining

Marinating is primarily used to add flavour and modify surface texture. Brining uses a measured salt solution to change seasoning, water retention and texture. A marinade may contain salt, but it is not automatically a brine.

Food-safety considerations

Keep raw meat, poultry and seafood under refrigeration while marinating. Do not reuse raw marinade as a sauce unless it is handled through an approved cooking process. Acidic marinades do not reliably make raw food safe or eliminate pathogens.

Chef’s tip: Use a non-reactive container, keep the product covered and refrigerated, and pat the surface dry when a good sear is desired.

Key distinction: Marinating adds flavour and may alter surface texture; it does not guarantee deep tenderization or make raw food safe to eat.
