The chefs must make use of ingredients that are usually thrown out, for being imperfect, overripe or stale. For example, the first basket includes juicer pulp and tea bags. Then in the second round, the competitors have to get creative with a little bit of salad dressing and some paltry scraps of poultry. And the finalists get some often-tossed portions of a fruit and the peels of a veggie to work into their desserts.
