Chinois

Also: China cap, conical strainer, bouillon strainer, passoire chinois

A fine-mesh, cone-shaped metal strainer used in classical French cuisine to pass stocks, sauces, and purées to an ultra-smooth consistency by forcing liquid through its dense mesh with a ladle or pestle.

/sheen-WAH/French: chinois (Chinese), likely referring to the hat-like shape resembling a conical Asian straw hat (douli). Standard professional kitchen terminology in French cuisine since at least the 19th century.

Definition

The chinois is one of the most precision-demanding tools in the classical French brigade kitchen. Its form is distinctive and intentional: a deep, steeply tapered cone of extremely fine woven stainless steel mesh, terminating in a blunt tip, with a looped handle at the apex and a hook or hook-and-rod assembly to rest it over a pot or bain-marie insert. The conical geometry serves two functions: it concentrates all the liquid at the tip where the pressure of a rotating ladle or the systematic force of a pestle (a cone-shaped wooden or metal tamis pestle) can push it through the mesh with maximum efficiency, and the steep sides expose nearly the entire mesh area to the contents being strained rather than forcing all liquid through a flat disc bottom. In a professional kitchen, straining through a chinois is a two-step process: the finished stock, sauce, or coulis is first passed through a coarser conical strainer (called a China cap or passoire) to remove large solids, then a second pass through the fine-mesh chinois removes every trace of fat globule, vegetable fiber, and connective tissue fragment, producing the glass-clear consommé or the satin-smooth velouté that defines classical sauce cookery at its highest level. The ladle technique is essential: rather than simply pouring the liquid and letting gravity do the work, the cook presses the back of a ladle in gentle rotary circles against the mesh, forcing liquid through the fine weave while preventing solids from clogging the mesh pores. For coulis and purées, a wider circular motion with increasing pressure is used; for delicate consommé, minimal pressure preserves the clarity by avoiding any agitation of the sediment. The chinois is also the tool for pressing fat from a resting stock through the mesh to estimate yield and capture even the last tablespoon of stock from the solids.

In use

“She set the chinois over a tall cylindrical container, ladled in the veal stock one scoop at a time, and worked each portion through the mesh in slow circles until only a dry, compacted mass of vegetables and bones remained in the cone.”

Notes

Chinois vs. China cap: a frequent confusion

The terms 'chinois' and 'China cap' are often used interchangeably in English, but in professional kitchens they describe two distinct tools. The China cap (or coarse strainer) has large perforations — roughly 2–4 mm holes punched in a stainless cone — and is used for the initial straining of stocks and large-solids removal. The chinois proper has an extremely fine woven-wire mesh (100–200 mesh count per inch) and is used for the final, ultra-smooth pass. Both tools share the same conical geometry and ladle-pressing technique, but their fineness differs by an order of magnitude.

Mesh care and maintenance

The fine mesh of a proper chinois is difficult to clean and must be attended to immediately after use — proteins and fats that dry in the weave are nearly impossible to remove and will cause mesh corrosion over time. Professional practice is to run boiling water through the mesh from the outside immediately after straining, then scrub gently with a soft brush. The chinois should never be cleaned with a metal scourer or in a dishwasher with caustic detergent, as both degrade the fine woven mesh quickly. A well-maintained chinois lasts decades in a professional kitchen.

The pestle vs. ladle debate

Some classical kitchens use a cone-shaped wooden pestle (matching the angle of the chinois cone) to press purées and coulis through the mesh, arguing the pestle's broader contact surface moves material more efficiently than the curved ladle back. For clear stocks, however, the ladle is always preferred because the pestle applies pressure that can agitate and cloud the liquid. The choice depends on the product: purée and coulis — pestle; stock and sauce — ladle.
