It describes how the forest provides trees, grasses, fruits, flowers, mushrooms and honey with hidden flavors that were traditionally part of Filipino cuisine but are now unknown and undervalued. It also mentions how open kitchens in the Batulao Forest are working to preserve these flavors by having staff prepare meals using ingredients like binacol, humba and sotanghon that showcase the heirloom flavors of the forest.
