Catering: cooking for a date that cannot be moved

The meal is served at 8.15 pm. Not 8.30. There will be a hundred and twenty guests, not a hundred and ten. The venue is a hired hall with no kitchen, no cold room and sometimes no power socket where one is needed. And there is no second sitting to make up for the first. The whole trade of catering lives inside those four constraints.

An activity defined by the client's location

Activity classifications put it with useful precision. The United Nations international nomenclature defines event catering as the provision of food services under a contractual arrangement with the customer, at the location the customer specifies, for a particular event. The French nomenclature follows exactly the same logic and illustrates it: weddings, banquets, cocktail parties, buffets, lunches and receptions of all kinds, at the client's home or in venues they have chosen.

Two words carry the whole trade: contract and the client's location. A caterer does not receive guests, they travel. They do not offer a standing menu, they answer a one-off request. They do not meet their clients on the night, they have known them for weeks.

Those same nomenclatures exclude from this activity the manufacture of perishable food for resale and food retailing: a caterer who opens a takeaway shop is not extending the trade, they are adding a second one with its own rules.

Everything is decided beforehand

The visible work lasts a few hours. The real work starts weeks earlier, and it is first of all a work of questions.

Exactly how many guests, and by what date will the list be final? What kind of meal — seated, buffet, standing reception, several formats in succession? What service time, and what happens before and after? Are there particular diets, dietary prohibitions, allergies? Who supplies the tables, chairs, crockery, linen? Is there floor staff, and how many?

A serious catering quotation answers those questions rather than displaying a per-head price. It states what is included and what is not, the team's arrival time, the finish time, the date on which guest numbers are locked, and what happens if that number changes. It is the document that prevents almost every dispute in the trade.

Visiting the venue

An experienced professional does not take a booking in a venue they have not seen, or at least have not obtained a precise description of.

What they look at has nothing to do with cooking: how do you get in with equipment, is there vehicle access and how far away, is there a lift or stairs, where can a plating area be set up out of sight, how many power sockets and at what rating, is there water, where is washing-up done, where does the waste go, how far is the plating area from the tables.

Those details shape the menu as much as the client's taste does. A dish needing last-minute reheating is not feasible without a hot point. Plating a hundred and twenty covers is not feasible on two metres of table. A competent caterer adapts the proposal to what the venue allows, and says so before signing rather than discovering it on the day.

Producing in series without producing identically

A caterer's production resembles neither a restaurant's nor a factory's.

A large number of rigorously similar portions must be made, in a constrained time, with equipment that then has to be transported. That imposes precise technical choices: favouring preparations that survive waiting and travel, separating elements that come together at the last moment, cooking some things just before departure and others on site, and calibrating portions to the gram, because one over-generous portion repeated a hundred and twenty times means running short at the end.

Calculating quantities is a skill in itself. It cannot be deduced from a universal rule: it depends on the kind of event, the hour, the duration, the make-up of the guest list and the number of different offerings. It is one of the points where experience shows most.

Transport is the riskiest part

Between the kitchen and the table there is a road. That is where a caterer loses control of the product unless they have organised for it.

You have to think about packing — suitable containers, wrapping, wedging so nothing moves — about separating cold from hot, about holding temperature for the whole journey, about loading order so that what comes out first is reachable first, and about the fact that the vehicle must be clean and dedicated to that use.

The World Health Organization estimates that 866 million people — almost one in nine worldwide — fall ill each year after eating contaminated food, and that these illnesses cause around 1.52 million deaths a year. The hazards are biological first: bacteria, viruses, parasites. An event by definition gathers many people around the same meal, which makes the stake particular — one mistake does not affect one customer, it affects a hundred.

The international reference framework is the Codex Alimentarius collection of codes of practice, developed jointly by FAO and WHO, whose general principles of food hygiene serve as the basis for every other hygiene text. Temperature control sits at its centre: sensitive preparations kept cold until the last moment, reheating done quickly and thoroughly, hot holding times limited and monitored, and a deliberate refusal to keep anything that has spent too long outside its safe range.

The precise obligations — approval or registration of the production kitchen, transport equipment, temperature records, staff training — belong to each country's regulation. They vary a great deal, and it is always the local rule that must be known before selling a service.

The day itself: set up, serve, break down

On site the job unfolds in three phases the client does not perceive as separate.

Set-up: arriving well before the announced hour, installing the plating area, laying the tables if that is included, bringing food up to temperature, a final check on guest numbers.

Service: this is where the number of people on the floor becomes decisive. Serving a hundred and twenty plates in an acceptable time requires a team that is sized and briefed — who serves which table, in what order, on what signal. A service that stretches out leaves the first plates cooling and the last guests waiting.

Break-down, finally, which clients always forget to count: clearing, repacking, cleaning, removing waste, leaving the venue as it was found. A caterer who leaves a dirty hall will not be recommended, whatever the quality of the meal.

What the client is really buying

They think they are buying a menu. They are actually buying peace of mind.

Someone organising a wedding, a significant birthday or a company seminar already has a dozen things to manage. What they want from a caterer is to remove one of them from the list. That means answering messages, confirming in writing, arriving at the stated time, raising difficulties yourself, and not turning a hitch into the client's problem.

It is also why recommendation is the trade's primary channel. A successful event is seen by dozens of people who will organise their own one day. Conversely, an incident is retold for a long time.

The economics of a job

The per-head price on its own says almost nothing. A catering job combines costs of very different natures.

There is the raw material, the only part that genuinely scales with guest numbers. There is production time, which rises more slowly than guest numbers — which is what makes small events proportionally more expensive. There is service staff, counted in people and hours, set-up and break-down included. There is logistics: vehicle, fuel, hired equipment, crockery, linen, packaging. And there is the margin of safety: what you plan in excess so as never to run short.

A caterer who bills purely per head without distinguishing these lines penalises themselves on small events and on distant jobs. A detailed quotation protects both sides and makes comparison honest.

Presenting a catering business

A client looking for a caterer wants to know very quickly whether you can do what they have in mind, on their date, at their venue.

A professional presentation therefore gives: the name of the business and what it does in one sentence, the types of work you genuinely take on — weddings, corporate receptions, cocktail parties, buffets, seated meals, family events — sample menus or packages, the range of guest numbers you can handle, the geographical area covered and your terms beyond it, the notice you prefer, what a standard job includes and what it does not, whether you can supply floor staff, crockery and furniture, how to request a quotation, and a contact that answers quickly.

Two elements matter especially. The guest numbers you can serve: it is the client's first filter, and it prevents impossible enquiries in both directions. And photographs of your real work: someone organising an important event buys on evidence, not on promises. Show laid tables, buffets, dishes, the team in service.

Finally, state what you can do about dietary constraints — particular diets, allergies notified in advance, adapted menus. Being able to answer "what is in it?" precisely is part of the trade, and information obligations vary between countries.

In short

Catering is a trade of production away from your own walls, for a single date and a venue you do not control. Its skill is not only culinary: it is logistical, contractual and organisational. You calculate quantities in advance, transport sensitive products, install yourself in a venue you had to survey, serve everyone at once, then erase your presence.

Obligations on production premises, transport, temperature and training depend on the country and sometimes the local authority: local rules apply. What does not vary is the founding constraint — there is no second chance, and the client knows it before they even sign.

Are you a caterer? Set out the kinds of events you cover, your guest capacity, your area and your lead times: that is what people check before asking for a quotation.
