Morphology

key + ingredient

The meaning is directly and compositionally derived from 'key' (important, essential) + 'ingredient' (a component or element); together they straightforwardly mean the essential component. This adjective+noun collocation follows a common compositional pattern found across languages, so a B1 learner who knows both words will readily infer the MWE meaning.

Etymology

Key ingredient uses key, a small tool that opens a lock, and ingredient, a part of a recipe. Imagine one spice that seems to 'unlock' the full taste of a dish — that small part makes everything work, so key ingredient means the 'most important part' of something.
