When we talk about something that is "more half-cooked," we are referring to a situation where something is not entirely ready or still needs some work. The antonyms for this phrase could include "fully cooked," "well-done," "mature," "ripe," or "complete." These words suggest completeness or finality and imply that there is no further work to be done. Conversely, "unfinished," "raw," "immature," "incomplete," or "underdeveloped" could be suitable synonyms for "more half-cooked." Using these antonyms may help to better describe or understand the nature of the situation, particularly when discussing a project or goal that requires further development.
