Wholesale produce supplier for caterers: sourcing for events

A wholesale produce supplier for caterers has a different job from one that serves a single restaurant. A restaurant works through roughly the same list every week and tweaks it at the edges. A caterer might do forty covers on Tuesday and four hundred on Saturday, cook a menu once and never repeat it, and work to a date that cannot move. Buying fruit and veg against that shape takes planning a standing weekly order never needs — and a supplier who flexes with you rather than one built around one fixed drop.

This is a guide to sourcing produce for event and contract catering: how the buying differs, what to look for, and how to place an order so a big service is covered without a wall of waste behind it.

Why a wholesale produce supplier for caterers buys differently

The hard part of catering is that the volume keeps changing. Three things make produce buying for caterers unlike a restaurant's:

• The numbers swing. A quiet midweek drop and a 300-cover wedding can fall in the same seven days. Your order has to breathe with the diary rather than settle at a steady weekly figure.
• The dates are fixed. A restaurant can push a dish to tomorrow if a delivery falls short. A wedding lunch at one o'clock cannot move, so the produce has to be right the first time.
• The menus are often one-offs. You cost and cook a canapé list once, then never again. There's no month of repeat orders to smooth out a bad guess on quantity.

Add the range of formats a caterer runs — canapés, bowl food, buffets, plated banquets, festival trading — and you're buying for several different kitchens at once. That is a sourcing problem before it is a cooking one.

What should a caterer look for in a produce supplier?

A caterer should look for a supplier who answers to the diary rather than the calendar: someone who takes a late-changing order, delivers on the days you need, and picks fresh close to service. Ortaggi orders close at midnight by phone, WhatsApp or email, and routes run Monday to Saturday across London and the South East, so a Saturday event can be ordered against on Friday night. Produce is hand-picked at New Covent Garden Market each morning from around half past midnight and delivered before service, which is what lets a caterer commit to a fixed date with the freshest stock behind it.

The wider judgement calls — cut-offs, substitutions, provenance, how a supplier behaves on a bad morning — are worth putting to any supplier before you commit. Our checklist of questions to ask a wholesale produce supplier runs through them in plain terms; the answers matter more to a caterer than to anyone, because you rarely get a second service to fix a miss.

Match your order to the shape of the event

Build a catering order from two things: a covers count and the menu, in that order. Start with confirmed numbers, add a sensible contingency for the format — a walk-around canapé reception is harder to portion than a seated lunch — and only then translate the menu into a produce list. Working backwards from "what did we order last time" is how a caterer ends up long on one line and short on another.

Trim waste at the list stage rather than in the kitchen. Order whole where you'll use it and specify a size that matches the job: large, uniform potatoes for a fondant, smaller grades for a crushed side. Ask how many to a box on the lines that dominate a big prep, so your team can plan labour against real numbers instead of guessing on the day. A tight list beats a generous one every time you'd otherwise be paying to bin trim.

Hold your spec when the numbers get big

Consistency is the thing that breaks first at volume. Four covers forgive a variable box of tomatoes; four hundred do not, because one soft crate throws a whole section behind at exactly the moment there's no slack to absorb it. Write a spec — variety, size, grade, ripeness — and hold your supplier to it across the whole order, down to the last tray off the van.

Getting that down in writing is a skill in itself, and it pays back hardest on a large event. Our guide on how to spec fruit and veg for a kitchen covers how to pin a line down so the same thing lands every morning. For a caterer, a written spec also gives a relief chef or an agency prep team something to check the delivery against when your regular crew is spread across three jobs.

How do you order produce for a one-off event?

Order for a one-off event by giving the supplier three things: the date, the confirmed covers, and the menu or produce list — then place it by the cut-off the night before. With a midnight cut-off, a Saturday function can be firmed up on Friday evening once your final numbers are in, which is usually the last moment a caterer knows them.

Talk through substitutions before the order goes in, while there's still time to change the plan. Fresh produce is a living crop, and a line that didn't make grade overnight needs a route through — the nearest equivalent, a different variety, or a heads-up early enough to flex the dish. A supplier who sources to order helps here: if a speciality line isn't on the standard list, ask, and it can often be brought in for the date rather than left off it.

Buy with the season, not against it

Menu planning for an event is easier when it leans on what the market is landing. Produce that's in season arrives in better condition, in steadier supply and with more give on the quantities a big event demands — far better than chasing an out-of-season line that turns up thin and dear the week you need a hundred portions of it. Our weekly read from the market floor tracks what's changing hands; the late-September Market Note has the fruit board turning from summer stone fruit to new-season citrus and squash, which is the sort of shift worth building an autumn event menu around.

For a caterer this earns its keep as a planning tool. Lock the centrepieces of a menu to lines that will be plentiful on the date, and keep the flexible garnish work for whatever is best on the morning.

Where does the produce come from?

Ortaggi buys at New Covent Garden Market in Nine Elms, south-west London — the capital's main wholesale fruit and veg market, and the answer to "where is the wholesale vegetable market in London?" for most trade buyers. Buying is done by hand each morning from around 00:30, and the range covers chefs' staples through herbs, leaves, mushrooms and speciality lines, with anything off the standard list sourced on request. Delivery runs out of the market before morning service, across central and Greater London and into Kent, Surrey, Sussex and Essex.

That base matters to an event caterer for a simple reason: the produce is selected the same morning it reaches you, by people choosing it off the stands, rather than sitting a day or two in a depot on the way. For a fixed-date service, freshness on the morning is worth more than almost anything else on the invoice.

Different jobs, different produce needs

"Catering" covers a spread of businesses, and each buys produce a little differently:

• Event and banqueting caterers live on the swing between quiet weeks and huge single services — the volume-and-spec discipline above is the whole game.
• Contract caterers running canteens, care homes and school kitchens buy steadier lists but across many sites, so consistency and reliable delivery days carry the day.
• Caterers feeding film and TV productions work to long, unpredictable shoot diaries. Ortaggi supplies the caterer's kitchen for that work — the produce that feeds the unit, rather than delivering to the location itself.
• Festival and stadium traders need volume that lands in a tight window and holds up through a long trading day.

Whichever you are, the supplier question is the same one every trade kitchen asks — see our overview for caterers and event suppliers, and the wider picture of what a restaurant and trade food supplier does day to day. The buying just has to answer to your diary as closely as it answers to your menu.
