Cold chain, allergens and the paperwork

This is the part of catering nobody photographs and every professional gets right. Food between 5 and 63 degrees is food that is growing bacteria, and the whole discipline consists of minimising the time it spends there. Two hours is the working limit indoors, one hour in a hot garden, and the clock starts when the cool box is opened rather than when the guests sit down.

What a serious supplier shows you

Ask any caterer for three documents: their food business registration or licence, their public liability insurance, and their allergen matrix for your menu. All three exist in a real business and arrive within a day. A supplier who cannot produce them is not necessarily dangerous, but they are working without the structure that makes safety repeatable, and at a hundred covers that matters.

Allergens as a service discipline

Collect requirements in writing at the invitation stage, put them on the seating plan, hand that plan to the kitchen two days before, and let the captain carry a copy. The dish for the guest with the allergy is prepared separately, marked, and carried by one person who knows whose it is. Anything less than that is how the wrong plate reaches the wrong guest, which is the one failure in private dining that can end an evening in an ambulance.

Outdoors in summer

Heat shortens every limit. Butter, mayonnaise, cream, raw fish and anything with egg belong in a cool box until twenty minutes before they are eaten, and a buffet in 30 degree shade has a genuine life of about an hour. Build hot menus around dishes that are cooked and served immediately, and cold menus around things that are stable: cured, pickled, acidic, or simply robust.

The dietary matrix turns your guest list into a kitchen document, and the quantity calculator keeps the shopping proportionate so nothing sits around waiting to be used.
