NABTEB Catering Craft cheat sheet

Hospitality is the umbrella industry covering food and beverage service, accommodation, travel and tourism, and events; catering is the food and beverage subset.

Catering segments: commercial (restaurants, hotels, fast food, pubs) versus welfare or institutional (hospitals, schools, prisons, armed forces, staff canteens).

Contract catering is provided by an outside company on a client's premises under a service agreement; the client usually subsidises or pays per meal.

Off-premise catering (event, mobile, outdoor) prepares and serves food away from a fixed kitchen; on-premise catering serves within the operator's own premises.

Brigade de cuisine roles: executive chef, sous chef, chef de partie, commis chef, and kitchen porter; service side includes maître d'hôtel, chef de rang, and commis de rang.

Catering outlets are classified by service style: table service, counter service, self-service (buffet, cafeteria), and specialised (tray service, room service, airline).

Key hospitality characteristics: perishability, inseparability of production and consumption, variability, and intangibility of the service experience.

Nigerian catering contexts include buka or local eateries, hotel restaurants, outdoor catering for weddings and naming ceremonies, and industrial canteens.

Food commodities group into cereals and starches, pulses and legumes, vegetables and fruits, meat and offal, poultry and game, fish and seafood, dairy, fats and oils, sugars, and beverages.

Cereals (rice, maize, wheat, millet, sorghum) supply starch; when moist heat gelatinises starch, the grain softens and thickens the surrounding liquid.

Pulses such as beans, cowpeas, and groundnuts supply plant protein; soaking reduces cooking time and leaching of water-soluble vitamins.

Meat structure: muscle fibres, connective tissue (collagen and elastin), and fat; collagen converts to gelatine with long moist heat, tenderising tough cuts.

White fish has low fat and little connective tissue and cooks quickly; oily fish (mackerel, sardine, tuna) contains fat distributed through the flesh and spoils faster.

Dairy: milk is an emulsion of fat in water; heating with acid or enzymes coagulates the protein casein, forming curds used for cheese and yoghurt.

Fats and oils are used for shortening, frying medium, flavour, and emulsification; they smoke and break down when overheated, so reuse is limited.

Sugar functions as sweetener, preservative, colouring agent through caramelisation, and crystal controller in confectionery.

Equipment classes: large fixed equipment (ranges, ovens, refrigerators, steamers), mechanical equipment (mixers, slicers, food processors), and small utensils and hand tools.

Knife anatomy: blade, spine, edge, heel, tip, bolster, and handle; the chef's knife, paring knife, and serrated knife cover most preparation tasks.

Utensil materials: stainless steel resists corrosion, aluminium conducts heat well but reacts with acid foods, cast iron retains heat but rusts, copper conducts best and is costly.

Measuring tools include weigh scales for dry ingredients, graduated jugs for liquids, and measuring spoons; weighing is more accurate than volume for baking.

Heat sources: gas gives instant, controllable heat; electricity is cleaner and steadier; induction requires magnetic cookware; solid fuel and charcoal suit grills.

Refrigeration should hold 1-4 degrees Celsius (34-40 Fahrenheit) and freezers -18 degrees Celsius (0 Fahrenheit) or colder, checked with a thermometer.

Colour coding of chopping boards separates raw meat, fish, cooked food, vegetables, and bakery items to prevent cross-contamination.

Sanitation of equipment: wash in hot detergent water, rinse, sanitise with approved chemical or hot water, then air-dry; food-contact surfaces need regular checks.

Preparation steps: mise en place (gathering and prepping ingredients), weighing, washing, peeling, cutting into standard sizes, and portioning.

Moist heat methods: boiling (100 degrees Celsius at sea level), simmering (just below boiling), poaching (82-96 degrees Celsius), steaming, and stewing.

Dry heat methods: roasting, baking, grilling, broiling, and deep or shallow frying; dry heat browns food through the Maillard reaction and caramelisation.

Combination methods: braising and pot-roasting use searing followed by moist cooking; they suit tough cuts high in collagen.

Conduction transfers heat by direct contact, convection by moving air or liquid, and radiation by infrared waves; microwave cooking uses electromagnetic energy absorbed by water molecules.

Blanching briefly cooks food in boiling water then refreshes it in cold water to stop cooking and set colour.

Seasoning adds salt and pepper during cooking; flavouring adds herbs, spices, and aromatics; tasting and adjusting at each stage is standard practice.

Standard recipe cards fix ingredient quantities, yield, portion size, and method so results and costs stay consistent.

Service styles: silver or plated table service, family service, buffet, cafeteria, counter, tray, and room service; each changes staffing, equipment, and cost.

French service serves from a guéridon at the table; Russian service plates in the kitchen and carries to the guest; American or plated service is the most common.

Restaurant front-of-house roles: maître d'hôtel (seating and reservations), chef de rang (station head), commis de rang (assistant), and cashier.

The service sequence runs from reservation and greeting through seating, menu presentation, order taking, service, clearing, billing, and farewell.

A cover is one seated guest; covers per service and average spend per cover are core operating measures.

Table setting follows the rule of working outward from the plate; forks left, knives and spoons right, glasses above the knife.

Reservation and table-planning systems control seating capacity; overbooking and table-turn timing affect guest satisfaction and revenue.

Complaint handling: listen without interruption, apologise, act promptly, and follow up; records of complaints feed service improvement.

Food poisoning is mainly caused by bacteria (Salmonella, Staphylococcus aureus, Clostridium perfringens, Bacillus cereus, E. coli); viruses and chemicals also cause illness.

The danger zone is 5-63 degrees Celsius (41-145 Fahrenheit); bacteria multiply fastest there, so food should pass through it quickly.

Bacterial growth needs food, moisture, warmth, time, acidity level, and oxygen; removing any one factor limits multiplication.

Cross-contamination occurs when raw food or dirty hands and equipment touch ready-to-eat food; separate boards, knives, and storage prevent it.

Personal hygiene rules: clean uniform, tied hair, short nails, no jewellery, handwashing before work and after toilet or handling raw food, and exclusion of sick staff.

HACCP is a seven-principle system: hazard analysis, critical control points, limits, monitoring, corrective action, verification, and record keeping.

Pest control relies on proofing buildings, screening windows, storing waste in sealed bins, and regular inspection; poison and traps are placed away from food areas.

Kitchen safety hazards include slips, cuts, burns, and electrical shocks; fire blanket and dry powder extinguisher suit fat fires, never water.

Macronutrients: carbohydrates supply 4 kcal per gram, protein 4 kcal per gram, fat 9 kcal per gram; alcohol supplies 7 kcal per gram.

Balanced diet principles: adequacy, balance, calorie control, moderation, and variety; the food groups are energy foods, body-building foods, and protective foods.

Micronutrients: vitamins are organic and needed in small amounts; minerals are inorganic; water-soluble vitamins (B group, C) are lost through leaching and heat.

Protein quality: complete proteins (animal sources, soya) contain all essential amino acids; complementary plant combinations such as rice and beans improve the profile.

Menu types: à la carte (each item priced separately), table d'hôte (fixed price for a set meal), and du jour (dish of the day).

A balanced menu varies colour, texture, flavour, cooking method, and food group across courses and avoids repeating the main ingredient.

Special diets: diabetic (controlled sugar and refined carbohydrate), low-salt, low-fat, vegetarian, gluten-free, and allergy-aware menus need accurate ingredient checks.

Menu planning factors include customer profile, season, cost, available equipment and skill, nutrition balance, and food availability.

Flour strength depends on protein content: strong bread flour has high gluten-forming protein, soft cake flour has low protein, and pastry flour sits between.

Yeast fermentation produces carbon dioxide and alcohol; dough develops gluten through kneading, and proving allows gas to expand before baking.

Bread faults: too little kneading gives dense crumb, too much salt slows yeast, and under-proving gives a tight, torn crust.

Lamination alternates dough and fat layers; steam in the oven separates the layers, producing puff pastry rise.

Sugar stages by temperature: thread, soft ball, hard ball, soft crack, hard crack, and caramel; each stage suits different confectionery.

Creaming method beats fat and sugar until pale and fluffy before eggs and flour are folded in; the rubbed-in method cuts fat into flour for shortcrust.

Egg foams (sponge and meringue) trap air; stable foam needs clean utensils free of fat and careful folding to avoid deflation.

Chocolate requires tempering to stabilise cocoa butter crystals, giving snap, gloss, and resistance to bloom.

Food cost percentage = (cost of food sold divided by food sales) multiplied by 100; a common target range is 28-35 percent for restaurants.

Cost of food sold = opening stock + purchases - closing stock, adjusted for staff meals and transfers.

Selling price can be set by the food cost method (ingredient cost divided by target food cost percentage) or by the markup method (cost plus a percentage or multiplier).

Gross profit = sales minus cost of goods sold; net profit = gross profit minus operating expenses such as labour, rent, utilities, and marketing.

Break-even point in units = fixed costs divided by (selling price per unit minus variable cost per unit).

Portion control and standard yield testing reduce waste; the edible portion cost is the purchase cost divided by the yield percentage.

Labour cost percentage = labour cost divided by total sales, multiplied by 100; productivity is measured as covers or sales per labour hour.

Stock control uses minimum and maximum levels, reorder points, and stocktaking; FIFO rotation reduces spoilage and hidden loss.
