The legal requirement for receiving chilled high-risk foods like raw poultry is that it must be at or below 5°C to prevent rapid bacterial multiplication. Accepting meat at 8°C or 12°C places it in the temperature danger zone, while 0°C or below indicates freezing, which is incorrect for a fresh chilled delivery.

Braising is a combination cooking method that involves browning the meat first, then simmering it slowly in a small amount of liquid within a covered vessel. Submerging entirely is boiling or stewing, rapid cooking in fat is frying, and suspending over water is steaming.

A classic velouté is a foundational ‘mother sauce’ made by thickening a white stock (such as chicken, veal, or fish) with a blond roux. Using milk creates a béchamel, using brown stock creates an espagnole, and egg yolks with cream is a liaison used for finishing, not the base.

Slips and trips are major hazards in a commercial kitchen; an oil spill must be communicated immediately and cleaned up using absorbent paper and degreaser to remove the slip hazard. Leaving it, adding water, or using flour creates a dangerous, slippery paste that worsens the hazard.

Blind baking involves lining the raw pastry with parchment and baking beans to weigh it down, which stops the base from puffing up and the sides from collapsing. This ensures a crisp, fully cooked case that will not become soggy when a liquid filling is added.

Trussing ties the wings and legs closely to the body, creating a uniform shape that prevents the extremities from overcooking and drying out before the thicker parts are done. It does not seal in juices or speed up cooking; in fact, it slightly restricts airflow into the cavity.

Plunging cooked vegetables into ice water is known as refreshing (or shocking), and it instantly stops residual heat from overcooking the vegetables while locking in their bright colour. Blanching is the initial brief boiling process, and macerating involves soaking in liquid to soften or flavour.

Round fish, such as salmon, cod, and trout, yield exactly two fillets—one from either side of the backbone. Flatfish, such as sole or turbot, yield four fillets (two from the top and two from the bottom).

Coeliac disease requires strict avoidance of all gluten, and even microscopic cross-contamination can cause severe health issues. Gluten is a protein that cannot be destroyed by high cooking temperatures, and spelt/rye contain gluten, making those options dangerous.

Deep-frying relies on high heat to instantly seal the exterior of the food, creating a barrier that cooks the inside via steam. If the oil temperature drops too low, this barrier does not form quickly enough, allowing oil to seep into the batter and making it heavy and greasy.

A split mayonnaise (a cold emulsion) can be rescued by starting a new emulsion base with a fresh egg yolk and slowly whisking the broken mixture into it. Adding more oil will worsen the split, and applying heat will cook the egg yolks, ruining the sauce entirely.

Purée soups are naturally thickened by the starchy ingredients they contain (like potatoes, pulses, or root vegetables) once they are cooked and blended. While a liaison or roux is used in velouté or cream soups, purée soups rely on their own ingredient starches.

During roasting, heat forces the meat’s juices toward the centre. Resting allows the muscle fibres to relax and the juices to flow back through the meat evenly, so they stay inside the slices rather than bleeding out onto the cutting board. Carryover cooking actually continues during the resting phase.

Standard food safety rules dictate that raw meats must always be stored below cooked or ready-to-eat foods to prevent contaminated blood or juices from dripping onto safe food. Wrapping items does not override this fundamental top-to-bottom storage hierarchy.

In shallow poaching (cuisson), the high-quality cooking liquid captures the delicate flavours of the fish. It is standard practice to reduce this liquid and finish it with butter or cream to create a matching sauce (like a vin blanc sauce). Discarding it wastes essential flavour.

A julienne is a classic French knife cut resulting in thin, matchstick-like strips typically 2mm x 2mm x 40mm. A 5mm dice is a macedoine or brunoise (depending on exact size), 10mm sticks are batons, and flat squares are paysanne.

Crème anglaise relies on egg yolks for thickening. Egg yolks coagulate (cook and scramble) at around 82°C (180°F). If the mixture reaches boiling point (100°C), the proteins will tightly bind and separate from the liquid, ruining the smooth texture of the custard.

Mandolines have exceptionally sharp, exposed blades that cause severe hand injuries in commercial kitchens. The primary safety rule is to never use the bare hand near the blade; the provided safety guard or a protective cut-resistant glove must always be used.

A blanquette is a classic white stew where the meat is blanched (briefly boiled and rinsed) to remove impurities without browning, keeping the sauce white. Brown stews require searing the meat in hot fat to initiate the Maillard reaction, which gives the sauce a deep brown colour.

Steaming uses vaporized water to cook food without the addition of any fats, making it an ideal method for low-fat dietary requirements. Deep-frying, pan-frying, and confit all involve cooking the food in significant amounts of fat or oil, which contradicts a low-fat diet.
