Harry, who has spent the last ten years of his life being rather poorly fed, is astonished to see a vast display of delicious food appear on the golden plates after the Sorting:
Harry’s mouth fell open. The dishes in front of him were now piled with food. He had never seen so many things he liked to eat on one table: roast beef, roast chicken, pork chops and lamb chops, sausages, bacon and steak, boiled potatoes, roast potatoes, fries, Yorkshire pudding, peas, carrots, gravy, ketchup, and, for some strange reason, peppermint humbugs.
The Dursleys had never exactly starved Harry, but he’d never been allowed to eat as much as he liked. Dudley had always taken anything that Harry really wanted, even if It made him sick. Harry piled his plate with a bit of everything except the peppermints and began to eat. It was all delicious.
After they’d eaten, dessert appeared:
When everyone had eaten as much as they could, the remains of the food faded from the plates, leaving them sparkling clean as before. A moment later the desserts appeared. Blocks of ice cream in every flavor you could think of, apple pies, treacle tarts, chocolate eclairs and jam doughnuts, trifle, strawberries, Jell-O, rice pudding — (PS7)
