Stock is a foundational liquid preparation in cooking, produced by simmering bones, meat, fish or vegetables with water and aromatics to extract flavor, body and nutrients. In classical cuisine the technique was codified by chefs such as Marie-Antoine Carême and refined by Auguste Escoffier, who helped standardize stocks as the backbone of sauces and soups. Modern cooks still rely on stocks to provide depth that cannot be achieved by plain water or single-seasoning broths.
Characteristics and common types
Stocks vary by main ingredient and technique. A few widely used categories are:
- Chicken stock — made with poultry bones and trimmings; versatile and often clear when strained.
- Beef or veal stock — typically made from roasted or raw bones; longer simmering releases collagen and yields a richer, gelatinous body when chilled.
- Fish stock (fumet) — made from fish bones and heads; cooked quickly to avoid bitterness and over-extraction.
- Vegetable stock — made from onions, carrots, celery and other vegetables for a meatless base.
Mirepoix (a mix of onions, carrots and celery) and other aromatics are often added, sometimes tied into a bouquet garni to concentrate and later remove herbs. The result of a well-made stock is a clean, concentrated liquid that amplifies the flavors of the dish it supports.
Preparation and kitchen techniques
The basic method is gentle simmering: cover bones or vegetables with cold water, bring slowly to a bare simmer and cook long enough to extract flavor without vigorous boiling, which clouds the liquid. For a darker, more intense stock, bones may be roasted first; for a clearer stock, vegetables are often sweated rather than browned. Skimming any foam or impurities from the surface improves clarity and taste.
Some practical notes: fish stocks are brief and fragile, finished in about twenty minutes to half an hour; beef and veal stocks benefit from several hours of simmering to draw out gelatin and minerals. Modern appliances such as pressure cookers can shorten extraction time, while slow-cookers and ovens offer convenience for long, low-temperature extraction.

Uses, examples and culinary importance
Stock is used directly as the base of soups and stews, or reduced and combined with other ingredients to make sauces and gravies. It is the starting point for preparations such as gravy, consomé (clarified stock), velouté and demi-glace (reduced brown stock), and for cooking grains and legumes to infuse them with flavor. Stocks also play a key role in braising and poaching, where their richness contributes to the finished texture of meats and vegetables.
Storage, safety and quick methods
Fresh stock can be refrigerated for a few days; many cooks refrigerate for three to four days or cool and freeze portions for months. Re-boiling stored stock before use is a traditional safety step. Clear labeling and rapid cooling help avoid spoilage. Commercial bouillon or stock cubes offer convenient, concentrated flavor in a pinch, and ready-made stocks are widely available for home cooks.

Distinctions and notable facts
Stock is often contrasted with broth: stock emphasizes extraction from bones (and therefore gelatin and mouthfeel), while broth is sometimes made mainly from meat and can be seasoned for direct consumption. Consomé is a clarified, intensely flavored stock. Commercial products such as bouillon cubes or powdered soup bases provide convenience but differ in concentration, salt level and additives.
