4. Waste Not

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.

And the finalists get some often-tossed portions of a fruit and the peels of a veggie to work into their desserts.
