Part of the attraction of a buffet is that you can take whatever you want. But that's a double-edged sword. The kitchen has to prepare a wide range of selections, but not all is eaten. And when guests have eyes larger than their stomachs, they create plate waste.
Last Wednesday, students learned how the hotel uses its food scraps, as part of Young Post's "Waste Not, Want Not" campaign.
"They have to look not just at controlling the wastage, but also hygiene," Yeung says. "The number one thing is whether the food is safe to eat. We want to make sure our guests leave the restaurant happy and well."
The seafood on ice from the night before may still taste delicious, but diners could fall ill if they eat it, as bacteria might have started to grow on the prawns, mussels and crabs. Yeung uses the leftovers to make a soup.
"By roasting the seafood in the oven, high temperatures kill the bacteria while retaining all those juicy flavours," he says.
Yeung even uses carrot peel to make vegetable stock with onions and celery, which can be used as the base for many sauces. That works for fish and meat bones too, he adds.
Other tricks include turning leftover beef, lamp chops, and steaks into a hearty stew to be served for staff, and grating bits and pieces of cheese to make macaroni and cheese.
On the day of Young Post's visit, students watched pastry sous-chef Tak Chung make a bread pudding with excess baguettes, rolls and ciabatta from the breakfast buffet. He sliced the leftover bread and spread it at the bottom of a baking dish. Then he covered the bread with a mixture of whisked eggs, cream, sugar and vanilla. After baking it in the oven, the stale bread became a delicious dessert.
"You can use croissants, too, which make the dessert more buttery," says Chung. "But it's best to avoid bread with filling, like chocolate Danishes or cocktail buns."
