A written formula that fixes ingredient quantities, yields, portion sizes, and method so a dish tastes and costs the same no matter who prepares it.

Related: Recipe yield, Portion cost, Mise en place
Recipe yield

The total quantity or number of portions a recipe produces after preparation and cooking, used to calculate portion size and per-serving cost.

Related: Standardized recipe, Portion cost
Portion cost

The food cost of a single serving, found by dividing total recipe cost by the number of portions the recipe yields.

Related: Recipe yield, Food cost percentage
Food cost percentage

A ratio comparing the cost of food sold to food sales revenue, expressed as a percentage and used to judge whether menu pricing and controls are working.

Related: Portion cost, Menu engineering
Menu engineering

A method of rating menu items by both sales popularity and contribution margin, then adjusting placement, pricing, or recipes to improve overall profitability.

Related: Food cost percentage, Contribution margin
Contribution margin

The money left from an item's selling price after its food cost is subtracted; it shows how much each sale contributes toward labor, overhead, and profit.

Edible portion yield

The share of a purchased item's weight that remains usable after trimming, peeling, or boning, used to convert as-purchased amounts into as-served amounts.

Related: As-purchased cost, Portion cost
As-purchased cost

The price paid per unit of an item in the form it arrives from the supplier, before any trimming or preparation losses are accounted for.

Related: Edible portion yield, Par level
Par level

The target on-hand quantity of an item that covers expected use between deliveries plus a safety buffer, triggering a reorder when stock falls to it.

Related: As-purchased cost, FIFO rotation
FIFO rotation

First in, first out: a storage practice of placing newer deliveries behind older stock and using the oldest product first to limit spoilage and waste.

Related: Par level, Date marking
Date marking

Labeling prepared or opened foods with the date they were made or opened and a discard date, so staff use or throw out product within allowed holding limits.

Related: FIFO rotation, Temperature danger zone
Temperature danger zone

The range of roughly 41°F to 135°F (5°C to 57°C) in which bacteria multiply fastest; foods must be kept out of it or moved through it quickly.

Related: Date marking, HACCP plan, Two-stage cooling
Two-stage cooling

A required cooling method in which cooked food drops from 135°F to 70°F within two hours, then to 41°F or below within four more hours.

Related: Temperature danger zone, HACCP plan
HACCP plan

A written food safety system that identifies biological, chemical, and physical hazards at specific steps, sets critical limits, and defines monitoring, corrective actions, and verification.

Related: Critical control point, Temperature danger zone
Critical control point

A step in a food's flow where a control measure can prevent, eliminate, or reduce a hazard to an acceptable level, such as cooking or chilling.

Related: HACCP plan, Two-stage cooling
Cross-contamination

The transfer of harmful bacteria or allergens from one food, surface, or tool to another, often through shared cutting boards, hands, or unwashed utensils.

Related: Allergen control, Sanitizing
Allergen control

Procedures that prevent a major food allergen from reaching a guest who reacts to it, including separate tools, verified labels, and clear communication with service staff.

Related: Cross-contamination, Sanitizing
Sanitizing

Treating a cleaned food-contact surface with heat or an approved chemical to reduce microorganisms to levels considered safe by public health standards.

Related: Cross-contamination, Allergen control
Maillard reaction

The browning that occurs when amino acids and sugars react under high heat, producing savory flavors and color on seared, roasted, or toasted foods.

Related: Caramelization, Emulsion
Caramelization

The browning and flavor development that happens when sugars alone are heated to high temperatures, as in making caramel or browning onions.

Related: Maillard reaction
Emulsion

A stable mixture of two liquids that normally separate, such as oil and water, held together by an emulsifier like egg yolk or mustard.

Related: Maillard reaction, Gluten development
Gluten development

The formation of elastic protein strands when wheat flour is mixed with water and worked, giving structure to breads and toughness to overmixed batters.

Related: Emulsion
Standard operating procedure

A written, step-by-step instruction describing how a routine task must be performed so results are consistent and training is repeatable.

Related: Station setup, Mise en place
Station setup

The arrangement of equipment, tools, and ingredients at a work position so a cook can work efficiently without leaving the station or crossing other stations.

Related: Mise en place, Standard operating procedure
Cover

One guest served at a meal; covers are counted to forecast production, schedule labor, and measure sales per seat.

Related: Production forecast, Labor cost percentage
Production forecast

A prediction of how many guests and which menu items will be sold for a given period, used to plan purchasing, prep quantities, and staffing.

Related: Cover, Par level
Labor cost percentage

Total labor expense divided by sales revenue, expressed as a percentage; it tracks whether staffing levels are in line with business volume.

Related: Cover, Contribution margin
Prime cost

The combined total of food cost and labor cost, usually watched as a share of sales because these two expenses are the largest controllable costs in a kitchen.

Related: Food cost percentage, Labor cost percentage
Onboarding

The structured process of welcoming, orienting, and training a new hire in policies, safety, and job duties so they become productive and stay with the operation.

Related: Standard operating procedure, Progressive discipline
