WACS Primary cheat sheet

Professional identity is built on three pillars: technical competence, ethical conduct, and accountability to guests, colleagues, and the public.

Conflict of interest exists when personal interest could influence professional judgment; disclose it before decisions are made.

Plagiarism includes copying recipes, menus, or plating without attribution; credit the originator when adapting signature work.

Confidentiality covers recipes, cost data, supplier terms, and guest information; do not share outside the operation without authorization.

Accepting gifts from suppliers can create bias; most codes require disclosure or refusal of gifts above nominal value.

Harassment and discrimination violate professional ethics and law; report through established channels and document incidents.

A professional CV must be accurate; falsifying experience, titles, or certifications is grounds for dismissal and reputational harm.

Ethical sourcing means verifying claims about labor, animal welfare, and environmental impact rather than repeating marketing language.

Temperature danger zone is 5°C to 60°C (41°F to 140°F); minimize time food spends in this range.

Two-hour rule: ready-to-eat food held in the danger zone must be discarded after 2 hours cumulative exposure.

HACCP has seven principles: hazard analysis, CCP identification, critical limits, monitoring, corrective actions, verification, and recordkeeping.

A CCP is a step where control is essential to prevent, eliminate, or reduce a hazard to an acceptable level; a critical limit is the measurable boundary.

Handwashing requires soap, running water, and at least 20 seconds; wash before food contact, after raw protein, after restroom, and after waste handling.

Cross-contamination is prevented by color-coded boards, separate raw and ready-to-eat storage, and cleaning and sanitizing between tasks.

Cooling from 60°C to 20°C within 2 hours and from 20°C to 5°C within a further 4 hours is a common safe cooling protocol.

Reheating must reach 74°C (165°F) for at least 15 seconds within 2 hours; do not reheat more than once.

High-risk foods include raw and cooked meat, poultry, seafood, eggs, dairy, rice, and cooked pasta; they require strict time-temperature control.

Mise en place is the setup of ingredients, tools, and station before service; it reduces errors and improves speed.

The brigade system assigns stations: saucier, poissonnier, entremetier, garde manger, patissier, and commis, each with defined responsibilities.

Workflow design follows the order of production: receiving, storage, prep, cooking, plating, and washing, without crossing clean and dirty paths.

FIFO (first in, first out) rotation ensures older stock is used first; label and date all stored products.

Knife safety: carry with blade down and edge away, cut on a stable board, and never leave knives in a sink or across a walkway.

Equipment capacity must match menu volume; an overloaded oven or mixer produces uneven results and accelerates wear.

Cleaning schedules are documented per station and per equipment; sanitizing requires a contact time specified by the product label.

Standard recipes and yield tests are operational controls that keep cost, quality, and consistency aligned.

Wheat flour protein content determines use: cake flour about 7-9%, all-purpose 10-12%, bread flour 12-14%.

Gluten forms when glutenin and gliadin hydrate and are worked; fat and sugar inhibit gluten development.

Salt strengthens gluten and controls yeast; it should be weighed, not estimated, in bread formulas.

Fresh herbs are added late for aroma; dried herbs are added early to rehydrate and release flavor.

Maillard browning occurs between amino acids and reducing sugars above about 140°C (285°F); it requires dry heat and low moisture.

Caramelization is sugar pyrolysis, beginning around 160°C (320°F); it is distinct from Maillard browning.

Emulsions are stabilized by emulsifiers such as lecithin in egg yolk; a broken emulsion can be recovered by re-emulsifying with a small amount of liquid.

Fat carries flavor and conducts heat; smoke point determines suitability for frying, with refined oils generally higher than unrefined.

Dry-heat methods include roasting, grilling, broiling, sautéing, pan-frying, and deep-frying; moist-heat methods include poaching, simmering, boiling, and steaming.

Combination methods include braising, stewing, and pot-roasting; they use moist heat after an initial dry-heat sear.

Blanching is brief partial cooking in boiling water followed by ice-water shock to set color and stop enzyme action.

Searing browns the surface through Maillard reactions; it does not 'seal in' juices, which is a persistent myth.

Reduction concentrates flavor by evaporating water; it also concentrates salt, so seasoning must be adjusted after reduction.

Emulsification, thickening with roux or starch, and seasoning are finishing techniques that determine sauce texture and balance.

Resting meat after cooking allows juices to redistribute; large cuts rest 10-20 minutes, small cuts 3-5 minutes.

Knife cuts are defined by dimension: julienne 1-2 mm x 40 mm, brunoise 1-2 mm cubes, dice 6-20 mm depending on size name.

The 14 major allergens in many jurisdictions include celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, peanuts, sesame, soybeans, sulphur dioxide/sulphites, and tree nuts.

Allergen information must be accurate and available to guests; staff must know where allergens appear in every dish and in shared equipment.

Cross-contact is prevented by dedicated utensils, boards, fryers, and storage; cleaning alone may not remove allergen residues.

Macronutrients provide energy: carbohydrate 4 kcal/g, protein 4 kcal/g, fat 9 kcal/g, alcohol 7 kcal/g.

A balanced plate typically emphasizes vegetables and fruit, whole grains, lean protein, and unsaturated fats.

Dietary requirements include medical (allergy, coeliac disease, diabetes), ethical (vegan, vegetarian), and religious (halal, kosher) needs; each requires distinct controls.

Coeliac disease requires strict gluten avoidance; 'gluten-free' claims require verified ingredients and controlled preparation areas.

Nutrition labels and ingredient lists are the primary verification tools; recipes must be updated when suppliers or formulations change.

Food cost percentage = (cost of food sold / food sales) x 100; it is a core profitability indicator.

Portion cost = purchase price per unit / number of portions yielded; yield testing accounts for trim, cooking loss, and shrinkage.

Waste hierarchy: prevent, redistribute, recycle, recover, dispose; prevention has the greatest impact.

Menu engineering classifies items by popularity and contribution margin: stars, plowhorses, puzzles, and dogs.

Energy and water use can be reduced by loading equipment fully, switching off idle equipment, and fixing leaks promptly.

Seasonal and local purchasing can reduce transport emissions and cost, but must be verified rather than assumed.

Record waste by category and weight; measurement is the basis for reduction targets and staff accountability.

Inventory control through par levels, accurate receiving, and regular stocktakes reduces spoilage and theft.

A professional code of conduct typically covers integrity, respect, safety, and responsibility to the public.

Mentoring and knowledge sharing are ethical obligations in a profession that depends on apprenticeship and craft transmission.

Social media posts about employers, guests, or colleagues can breach confidentiality and damage professional standing.

Sustainability claims in marketing must be substantiated; greenwashing undermines trust and may breach consumer law.

Whistleblowing protections exist in many jurisdictions; report serious food safety or ethical breaches through appropriate channels.

Fair labor practices include accurate pay, safe hours, and respect for rest breaks; these are ethical and legal requirements.

Cultural appropriation in food requires care; credit origins and avoid misrepresenting traditional dishes.

Continuing professional development is part of ethical practice; skills and knowledge must be maintained and updated.

Bacterial growth is fastest between 20°C and 50°C; refrigeration at 5°C or below slows growth but does not stop it.

Spore-formers such as Clostridium perfringens and Bacillus cereus survive cooking; rapid cooling prevents germination.

Listeria monocytogenes grows at refrigeration temperatures and is a particular risk for ready-to-eat foods and vulnerable guests.

Salmonella is associated with raw poultry and eggs; Campylobacter with poultry; E. coli O157 with undercooked beef and contaminated produce.

Cleaning removes visible soil; sanitizing reduces microorganisms to safe levels; both steps are required.

Pest control requires proofing, waste management, and regular inspection; sightings must be logged and acted upon.

Personal hygiene includes clean uniform, restrained hair, short nails, no jewelry on hands, and exclusion of ill staff from food handling.

Allergen management is part of HACCP in many systems; undeclared allergens are a leading cause of food recalls.

Receiving checks include temperature, packaging integrity, dates, and quantity; reject non-compliant deliveries.

Dry storage should be cool, dry, and ventilated; keep off the floor and away from chemicals.

Refrigerator organization: ready-to-eat foods above raw foods; raw poultry and fish on the lowest shelves.

Freezer storage requires airtight packaging and date labels; avoid overfilling to maintain air circulation.

Onion varieties differ in pungency: yellow for cooking, red for raw, shallots for delicate sauces.

Fish freshness indicators: clear eyes, red gills, firm flesh, fresh sea smell, and springy texture.

Meat grades reflect marbling and maturity; aging improves tenderness through enzymatic breakdown.

Dairy: milk fat content determines whipping and cooking behavior; cream with at least 35% fat whips reliably.

Leavening agents: baking soda needs acid; baking powder contains acid and is activated by moisture and heat.

Chocolate: couverture has higher cocoa butter and requires tempering; compound coating uses other fats and does not temper.

Stock making: cold water start for clarity, gentle simmer, skim regularly, and strain without pressing.

Roux stages: white (cooked briefly), blond (lightly colored), brown (nutty); each thickens differently and adds distinct flavor.

Mother sauces: béchamel, velouté, espagnole, hollandaise, and tomato; derivatives include mornay, suprême, and béarnaise.

Hollandaise is a warm emulsion of egg yolk, butter, and acid; it can break if too hot or if butter is added too quickly.

Poaching temperature is 70-80°C (160-175°F); boiling is 100°C (212°F) at sea level and toughens protein.

Deep-frying temperature is typically 160-190°C (320-375°F); overcrowding lowers temperature and increases oil absorption.

Seasoning should be layered during cooking and adjusted at the end; acid, salt, fat, and heat are the primary balance levers.

Plating principles include balance, height, negative space, and temperature control; food should arrive as intended.

Allergen risk assessment must consider hidden ingredients such as sauces, marinades, stocks, and garnishes.

Shared fryers and grills are common cross-contact points; dedicated equipment or thorough cleaning is required.

Vegan diets exclude all animal products; vegetarian diets vary by whether eggs, dairy, and fish are included.

Halal and kosher requirements include approved ingredients, separate equipment, and certification; verify with the supplier.

Diabetes management may require carbohydrate awareness; portion control and balanced meals support blood glucose control.

Nutrition claims such as 'low fat' or 'high fibre' are regulated; use only approved wording and verify against composition.

Menu descriptions must not imply absence of an allergen unless verified; 'free from' claims require controls.

Staff training on allergens must be documented and refreshed; new staff must not serve food until trained.

Gross profit = selling price - food cost; gross profit margin = gross profit / selling price x 100.

Selling price can be set by food cost percentage method: price = portion cost / target food cost percentage.

Yield percentage = edible portion weight / as-purchased weight x 100; use it to calculate true portion cost.

Waste can be reduced by using trim in stocks, staff meals, or preserves, and by accurate forecasting.
