A hundred guests, one cold oven, Provence Verte

How much crockery and glassware does a table of a hundred guests actually need?

Count in tens, then add a margin for breakage and second helpings. For 100 guests, plan 120 to 130 dinner plates, 120 side plates if there is a starter or a cheese course, and 120 sets of cutlery. Glasses are the item people underestimate: three per guest is the working figure, one for water, one for wine, one for a second wine or a soft drink, so 300 to 360 glasses, plus 40 spare. Cups or small glasses for coffee add another 110 to 120.

Rental companies in the Var deliver by the crate, usually in multiples of 12 or 24, which is why the count is done in tens and then rounded up to the nearest crate. A hundred guests seated at round tables of eight need 13 tables, 13 tablecloths, and roughly 104 chairs. If the meal is a buffet that circulates rather than a seated service, plates drop to about 90 but the glass count stays the same, because guests put a glass down somewhere and pick up another.

Serving dishes matter as much as plates. A cold oven means the food arrives in the dish it was assembled in: 12 to 15 large platters for a hundred guests, plus 20 bowls for sides and sauces. Keep a written inventory taped inside the storage crate, and check it against the rental list the evening before. The organisers who run these meals in the Var, documented on shared tables in the Provence Verte, treat the crockery count as the first fixed number of the plan, because everything else, menu, transport, service, is built on top of it.

How do you plan a menu when the oven is cold and the guest count is fixed?

Start from the constraint, not from the recipe. A cold oven means no roasting, no gratin finished at the last minute, no dish that depends on a hot blast of air. The menu is therefore built around one baked item prepared in advance, plus cold and room-temperature dishes that improve rather than suffer with a few hours of rest.

A workable structure for 100 guests: a cold starter assembled in the dish, such as a tomato and mozzarella platter with olive oil and basil, or a melon and cured ham plate in summer; one main dish baked earlier in the day and held warm in insulated boxes, such as a slow-cooked lamb shoulder or a vegetable tian; two cold sides, one starch and one vegetable; a cheese board; and a cold dessert, a fruit tart or a chilled cream. The baked main is the only item that touches the oven, and it leaves the oven free for the dessert if the dessert is baked too, which is why the two are scheduled at different times.

Build the menu month by month from what the stalls actually carry. In the Provence Verte, the market calendar runs roughly like this: spring brings asparagus, broad beans, cherries and strawberries; summer brings tomatoes, courgettes, aubergines, melons, peaches and apricots; autumn brings figs, grapes, mushrooms and squash; winter brings leeks, cabbage, citrus and root vegetables. A menu that follows the stalls needs fewer ingredients and less handling, which matters when the kitchen is a domestic one and the team is not professional.

Fix the guest count before the menu, never after. A hundred guests is a number that decides the size of every pan, the number of platters, and the number of people needed to carry them. If the count moves by ten, the quantities move by ten per cent, and the crockery count moves with it.

What quantities per guest, and how is the food held safely from market to service?

Quantities per guest, for a full meal with starter, main, sides, cheese and dessert, sit in these ranges. Protein: 200 to 250 g raw weight per guest for a boneless dish, 300 to 350 g if there is a bone. Starch: 250 to 300 g cooked weight, so about 100 g raw rice or pasta, or 250 g potatoes. Vegetables: 200 to 250 g prepared weight. Starter: 150 to 200 g. Cheese: 60 to 80 g. Dessert: 100 to 120 g. Bread: 80 to 100 g. These figures assume adults and a seated meal; a buffet that circulates tends to run 10 to 15 per cent higher on the cold items and lower on the hot ones.

The safety chain is the part that cannot be improvised. Cold dishes stay at or below 4 °C from the market to the moment they are set out, which means insulated boxes with ice packs, not a car boot in July. Hot dishes stay at or above 63 °C, which means insulated containers filled at the last possible moment and opened only at service. The two-hour rule applies to the buffet itself: food that has been out for more than two hours is not put back in the cold chain. In the Var, summer service temperatures regularly pass 30 °C, so the practical window is closer to one hour for anything containing meat, fish, egg or dairy.

Organise the day in blocks. Market in the morning, with a written list by stall and a cool box in the vehicle. Preparation in the early afternoon, cold dishes first, baked dish into the oven when the cold work is done. Transport in the late afternoon, hot and cold in separate containers, with a thermometer in each. Service in the evening, with the cold items set out last and the hot items carried out in batches rather than all at once. Clean and return the next morning, with the rental crates counted against the inventory.

What does the day itself look like, hour by hour?

A hundred guests do not need a complicated schedule, they need a written one. A realistic chronology: 07:00 market, 10:00 return and unpack, 11:00 cold preparation, 14:00 baked dish into the oven, 16:00 cooling and packing, 17:30 transport, 18:30 table setting, 19:30 cold items out, 20:00 service begins, 21:30 hot items cleared, 22:00 dessert and coffee, 23:00 clearing, 08:00 next day return of rental equipment.

The schedule holds only if the crockery count and the menu were fixed first. A missing crate of glasses at 18:30 is not a schedule problem, it is a counting problem from three weeks earlier. Write the plan, tape it to the kitchen wall, and give one person the single job of checking it against the clock.

What tends to go wrong, and how is it avoided?

Three failures repeat. The first is glassware: guests take a clean glass rather than reuse one, so the count runs out before the wine does. Put a marker or a glass charm on each guest's glass, or accept the higher count. The second is the cold chain: a dish prepared at 11:00 and left on a worktop until 17:00 has spent six hours in the danger zone. Pack it in the cool box as soon as it is made, not when the car is loaded. The third is the oven: a single cold oven cannot finish four different hot dishes at once, so the menu must contain only one baked item, or the baked items must be scheduled in sequence with a holding plan for each.

None of this requires professional equipment. It requires counting in tens, building the menu from one oven and the market calendar, and keeping every dish on the right side of 4 °C or 63 °C from the stall to the plate.
