The antonyms for the word "more infused" could be "less saturated," "barely permeated," or "scarcely immersed." These words suggest a level of subtlety, restraint, or incompleteness, indicating that the infusion process has been limited in some way. For example, if you say that the tea is less saturated with flavors, it may mean that the tea leaves have not been steeped long enough or that the water temperature was too low. Similarly, if you say that the dish is barely permeated with spices, it could indicate that you wanted a milder flavor or that you ran out of ingredients. Overall, the antonyms for "more infused" imply a lower degree of intensity, complexity, or richness.
