Practice cuts: julienne, brunoise, batonnet, dice, chiffonade. Speed comes with repetition. Explain proper knife maintenance, honing vs sharpening, and safety protocols.

Implement HACCP for restaurant compliance. Seven principles: 1. Conduct hazard analysis (biological, chemical, physical). 2. Determine critical control points (CCPs). 3. Establish critical limits (temps, times, pH). 4. Monitor CCPs with logs. 5. Corrective actions when limits exceeded. 6. Verification procedures (audits). 7. Record-keeping and documentation. Example CCP: cooking chicken to 165°F. Temperature danger zone: 40-140°F. Train all staff. Regular audits. Explain pathogen growth, cross-contamination prevention, and health department requirements.

Create FDA-compliant nutrition labels. Requirements: serving size, calories, 13 nutrients (fat, cholesterol, sodium, carbs, protein, vitamins). Calculation: 1. List all ingredients with amounts. 2. Use USDA database for nutrient values. 3. Calculate per serving. 4. Round per FDA rules. Software: Genesis R&D, ReciPal. Rounding: calories to nearest 5, fat to nearest 0.5g. Claims: 'low fat' (<3g), 'high fiber' (5g+), 'good source' (10-19% DV). Explain daily values, label format updates 2020, and compliance deadlines.

Scale recipes accurately for catering. Scaling factor: desired servings ÷ original servings. Multiply all ingredients by factor. Challenges: 1. Spices scale at 50-75% (not linear). 2. Thickeners (flour, cornstarch) at 80%. 3. Leavening agents carefully. 4. Salt to taste. 5. Cooking time: doesn't double with quantity. Equipment limits: oven capacity, mixing bowl size. Test small batch first. Baker's percentage for bread: all ingredients as % of flour weight. Explain why some ingredients don't scale linearly and surface area vs volume ratio.

Efficient batch sauce prep for week. Sauces: 1. Marinara (pasta, pizza). 2. Vinaigrette (salads). 3. Teriyaki (stir-fry). 4. Garlic-herb butter (vegetables, bread). 5. Tahini dressing (bowls). Portions: 1-cup jars, label and date. Storage: refrigerate 5-7 days, freeze 3 months. Sunday routine: 2-3 hours, make all sauces, portion proteins, chop vegetables. Benefits: saves time, reduces takeout, consistent flavors. Equipment: food processor, immersion blender, mason jars. Explain time-blocking and food safety storage guidelines.

Science of flavor pairing and affinity. Principle: ingredients with shared flavor compounds pair well. Coffee + chocolate: both contain pyrazines (roasted, nutty notes). Other natural pairs: tomato + basil, strawberry + balsamic, pork + apple. Flavor wheel: use to identify complementary flavors. Contrasting pairs: sweet + salty, acid + fat. Applications: menu development, dessert creation, cocktails. Database: foodpairing.com for molecular analysis. Experiment: taste, document, iterate. Explain volatile compounds, aroma, and taste vs flavor difference.

Create signature spice blends. Garam Masala formula: 2 tbsp cumin seeds, 2 tbsp coriander seeds, 1 tbsp black peppercorns, 1 tsp cardamom pods, 4 cloves, 1 cinnamon stick, 1 bay leaf, 1/4 tsp nutmeg. Method: 1. Toast whole spices in dry pan until fragrant. 2. Cool completely. 3. Grind in spice grinder to fine powder. 4. Store in airtight container (lasts 3 months). Other blends: Ras el Hanout, Berbere, Za'atar, Chinese Five-Spice. Explain essential oils, toasting activates flavors, and grinding releases aromatics.

Professional catering event planning. Timeline 100-person wedding buffet: Day before: shop, prep vegetables, make sauces, bake desserts. Event day: -4 hours: arrive, set up kitchen. -3 hours: start cooking proteins. -2 hours: finish sides, keep warm. -1 hour: set buffet, chafing dishes. Service: replenish as needed, clear plates. Staffing: 1 chef, 2 cooks, 3 servers. Equipment: warmers, coolers, transport containers. Checklist: permits, insurance, contracts. Calculate food quantities: 1.5 servings per person. Explain flow, timing, and contingency planning.
