No one could figure out how I coaxed such hearty flavor out of a few chicken bones, or made such wonderful fish fumet with fish racks and shrimp shells, all in the limited time available. Had my instructors given me a pat-down before class they might have learned my secret: two glassine envelopes of Minor's chicken and lobster base inside my chef's coat, for that little extra kick. They never figured it out.
