ACF Chef de Cuisine (CCC) cheat sheet

Maillard reaction: browning between amino acids and reducing sugars, optimal at 140–165°C (280–330°F); requires dry heat and alkaline conditions.

Carryover cooking: internal temperature rises 3–8°C (5–15°F) after removal from heat; rest large roasts 15–20 minutes before carving.

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

Emulsion: dispersion of fat in water (oil-in-water) or water in fat (water-in-oil); stable emulsions require an emulsifier (lecithin, mustard) and mechanical shear.

Starch gelatinization: starch granules absorb water and swell when heated to 60–95°C (140–203°F), thickening liquids; amylase enzymes thin sauces over time.

Protein denaturation: heat, acid, or salt alters protein structure; coagulation follows (e.g., egg proteins set at 63–70°C / 145–158°F).

Culinary ratios (by weight): vinaigrette 3:1 oil to vinegar; pie dough 3:2:1 flour:fat:water; rice pilaf 1:2 rice to liquid.

USDA yield grades for beef: Yield Grade 1 (highest cutability) through 5 (lowest); Quality grades: Prime, Choice, Select, Standard, Commercial, Utility, Cutter, Canner.

Plate cost = sum of (ingredient quantity used × unit cost) for all components on the plate, including garnish and oil for frying.

Selling price = plate cost ÷ target food cost percentage. Example: $4.00 plate cost ÷ 0.30 = $13.33.

As-purchased (AP) cost vs. edible-portion (EP) cost: EP cost = AP cost ÷ yield percentage. Example: $2.00/lb AP ÷ 0.80 yield = $2.50/lb EP.

Menu engineering matrix: stars (high popularity, high contribution margin), plowhorses (high popularity, low margin), puzzles (low popularity, high margin), dogs (low popularity, low margin).

Contribution margin = selling price − plate cost; use contribution margin, not food cost %, to evaluate menu item profitability.

Menu mix percentage = (number of an item sold ÷ total items sold) × 100; compare to expected popularity (70% rule: items below 70% of average popularity are low-popularity).

Recipe costing must include all ingredients by weight or volume; convert volume measures to weight for accuracy (1 cup flour ≈ 120 g).

Target food cost percentage is set by operation type: fine dining 28–32%, casual 30–35%, quick service 25–30%.

Standard recipe format includes: yield, portion size, ingredients by weight/volume, method, equipment, and critical control points.

Production schedule: forecast covers (number of guests) × item popularity percentage = projected item sales; use to determine prep quantities.

Par levels: minimum quantity of prepped items to have on hand; reorder when inventory falls to par.

Batch cooking: cook in small batches to maintain quality and reduce waste; hold hot foods at 57°C (135°F) or above.

Cross-utilization: use trim and by-products in other menu items (e.g., bones for stock, vegetable trim for soup) to reduce waste and cost.

Yield testing: determine actual usable product from a whole item (e.g., beef tenderloin yield ≈ 50–60% after trimming).

Mise en place: all ingredients prepped, measured, and organized before service; reduces ticket times and errors.

Ticket time management: target average ticket time by station; identify bottlenecks (e.g., grill station) and adjust staffing or prep.

Temperature Danger Zone: 5°C–57°C (41°F–135°F); limit time in this zone to 4 hours cumulative.

Two-stage cooling: 57°C to 21°C (135°F to 70°F) within 2 hours, then 21°C to 5°C (70°F to 41°F) within an additional 4 hours (total 6 hours).

HACCP seven principles: conduct hazard analysis, determine CCPs, establish critical limits, monitor CCPs, establish corrective actions, verify procedures, keep records.

Critical limit examples: cook poultry to 74°C (165°F) for 15 seconds; ground beef to 68°C (155°F) for 17 seconds; whole fish to 63°C (145°F) for 15 seconds.

Handwashing: wet hands, apply soap, scrub 10–15 seconds, rinse, dry with single-use towel; required after using restroom, handling raw food, coughing, or touching face.

FIFO (First In, First Out) rotation: store oldest products in front; label and date all prepared foods; discard ready-to-eat foods held over 7 days at 5°C (41°F) or below.

Cleaning vs. sanitizing: cleaning removes soil; sanitizing reduces microorganisms to safe levels. Chemical sanitizer concentration: chlorine 50–100 ppm, quaternary ammonium 200–400 ppm.

Cross-contamination prevention: separate cutting boards (color-coded), separate storage areas for raw and ready-to-eat foods, and never store raw foods above ready-to-eat foods.

Four-step training method: prepare (explain), present (demonstrate), practice (trainee performs), follow-up (evaluate and correct).

Job description components: title, summary, essential duties, qualifications, reporting relationship, and physical requirements.

Progressive discipline: verbal warning, written warning, suspension, termination; document each step with dates and specific behaviors.

Fair Labor Standards Act (FLSA): non-exempt employees must be paid overtime at 1.5× regular rate for hours over 40 in a workweek.

Turnover rate = (number of separations ÷ average number of employees) × 100; calculate monthly or annually.

Performance appraisal: use objective, behavior-based criteria (e.g., ticket times, attendance, sanitation scores) and conduct at least annually.

Onboarding: first 90 days critical; include orientation, safety training, and a 30-60-90 day review plan.

Delegation: assign task, grant authority, provide resources, set deadline, and follow up; match task to employee skill level.

Food cost percentage = (cost of food sold ÷ food sales) × 100. Cost of food sold = beginning inventory + purchases − ending inventory.

Labor cost percentage = (total labor cost ÷ total sales) × 100; includes wages, taxes, benefits, and meals.

Prime cost = food cost + labor cost; target prime cost is typically 60–65% of sales.

Break-even point (in sales) = fixed costs ÷ (1 − variable cost percentage). Example: $50,000 fixed ÷ (1 − 0.65) = $142,857.

Budget variance = actual − budget; favorable if actual expense < budget, unfavorable if actual > budget.

Inventory turnover = cost of food used ÷ average inventory value; higher turnover indicates efficient inventory management (target 4–8 times per month for perishables).

Contribution margin per item = selling price − variable cost per item; used for menu pricing and profitability analysis.

Operating profit = gross profit − operating expenses; gross profit = sales − cost of goods sold.

Purchase order (PO) must specify: item description, pack size, quantity, unit price, delivery date, and payment terms.

Receiving checklist: verify count, weight, quality, temperature (fresh 5°C/41°F or below; frozen −18°C/0°F or below), and documentation; reject substandard deliveries.

Invoice approval: match invoice to PO and receiving report (three-way match) before payment.

Inventory valuation methods: FIFO (first in, first out), LIFO (last in, first out), and weighted average; FIFO is standard for perishable food operations.

Par stock level = (usage during lead time) + (safety stock). Example: daily usage 10 cases × 3-day lead time = 30 cases + 5 safety = 35 cases.

Storage guidelines: dry storage 10–21°C (50–70°F) at 50–60% humidity; refrigerated storage 1–4°C (34–40°F); freezer storage −18°C (0°F) or below.

Inventory count frequency: at least monthly for full physical inventory; weekly for high-value or perishable items.

Approved supplier list: suppliers should be inspected and approved based on product quality, price, delivery reliability, and food safety compliance.

NSF/ANSI certification: equipment must be certified for sanitation and constructed with smooth, non-porous, cleanable surfaces.

Fire safety: Class K extinguishers for commercial cooking equipment (animal/vegetable oils); inspect monthly and service annually.

Ventilation: exhaust hoods must provide 100–200 cfm per linear foot of hood; make-up air must balance exhaust.

Equipment preventive maintenance schedule: daily (cleaning, temperature checks), weekly (deep clean), monthly (calibration), annually (professional service).

Electrical safety: GFCI outlets required within 6 feet of water sources; lockout/tagout procedures for equipment repair.

Slip and fall prevention: use non-slip mats, clean spills immediately, post wet-floor signs, and maintain proper drainage.

Refrigeration temperature monitoring: log temperatures at least twice daily; calibrate thermometers monthly in ice-point water (0°C/32°F).

OSHA Hazard Communication Standard: Safety Data Sheets (SDS) must be accessible for all chemicals; label all secondary containers.

Situational leadership: adapt style (directing, coaching, supporting, delegating) to follower readiness (ability and willingness).

SMART goals: Specific, Measurable, Achievable, Relevant, Time-bound; use for team and individual objectives.

Active listening: pay attention, show engagement, reflect back, clarify, and summarize; reduces miscommunication in the kitchen.

Conflict resolution: address issues privately, focus on behavior not personality, seek win-win solutions, and document outcomes.

Ethical standards: honesty, integrity, confidentiality, fair treatment, and compliance with laws and regulations.

Communication channels: pre-shift meeting (line-up), daily logbook, bulletin board, and digital messaging; ensure messages are clear and timely.

Team motivation: recognition, professional development, fair compensation, and a positive work environment reduce turnover.

Professional associations: American Culinary Federation (ACF) provides certification (CCC, CEC, CMC) and continuing education.
