稍加 is an adverb meaning 'to add slightly' or 'to make a slight addition or adjustment'. It combines 稍 (shāo), meaning 'slightly' or 'a little', and 加 (jiā), meaning 'to add' or 'to increase'. Together, they form a compact expression used to indicate a minor, deliberate modification — often to improve, refine, or correct something without major change.

This phrase is common in formal and semi-formal contexts, especially when giving instructions, offering suggestions, or describing subtle improvements in cooking, writing, teaching, or daily tasks. It implies intentionality and moderation: the speaker acknowledges that only a small amount of something — time, effort, ingredient, or attention — is needed. It is rarely used in casual speech among friends but appears frequently in written advice, manuals, and professional feedback.
