Morphology

cook + up

The meaning 'to prepare or make (a dish)' is directly derivable from combining 'cook' (prepare food) with the particle 'up', which adds a sense of completion or quick/inventive preparation; this compositional pattern is common and predictable for learners. Note that the provided definition of 'cook' in the input is the figurative 'cook the books' sense and is irrelevant here — using the ordinary 'prepare food' sense makes the expression clearly transparent to a B1 learner who knows both constituents.

Etymology

The phrasal verb cook up may come from the simple idea of making food: imagine mixing ingredients to create a new dish. When someone cooks up a story they are mixing facts and ideas in the same way, so it now means 'to invent or make up' something, often to trick people.
