Snack bars and banitsa shops in Burgas will serve more customers in December because of holiday orders. Mid-November is a good time to check display cases, while there is still time to repair or replace them.

From early December, offices order trays of snacks for parties, families buy trays of banitsa for gatherings, and kindergartens order rolls and milinki. They join the regular customers.

Near bus stops, markets and schools, snack bars are full from early morning. "Banitsa and boza" stays a morning habit in winter, and queues in December will be longer.

A snack bought at 10 or 11am should taste as good as the first tray out of the oven. A good heated display case keeps banitsa and rolls pleasant to eat late in the morning. Customers notice at once when banitsa has gone cold or dry.

A display case does not bake, finish baking or reheat cold food. It holds the temperature of food that has just come hot from the oven, and it must hold it evenly. Otherwise one end of the banitsa goes cold while the other dries out.

Some models for food outlets run between 30 and 90 °C. The hygiene rule for keeping hot food is about 63 °C, and a higher temperature over a long time dries out the dough.

Snacks go into the case while still warm, in small batches. Three refills during the morning are better than one overfilled case at 7am.

Display case size is given as the number of shelves, the volume in litres or the number of gastronorm trays. Before choosing a model, count the trays that come out of the oven in the busiest morning hour, and measure the counter by the till.

The case should not take up the space needed for the till and packing, and the shop assistant must be able to reach it freely from their side.
