Celiac plates are protected by dedicated equipment, a fixed order of work and sealed transport, applied the same way at every event. We use a countertop fryer reserved only for corn, yuca, plantain and potato, with oil that never meets wheat breading.
Purple-handled boards, knives, tongs and spatulas live in a sealed bin and are used only for allergy and celiac food. Gluten-free baking happens first thing in the morning, and the finished food goes into lidded containers on the top shelf of the cold room, above anything containing wheat.
Celiac plates travel covered in their own insulated carrier, each one labeled with the guest's name and table number. At the venue they are served before the main buffet opens, and staff wash their hands and change gloves before handling them.
