What does curded mean?
Curded is the past tense and past participle of the verb curdle, describing the process by which a liquid—most famously milk—separates into solid lumps called curds and the thin liquid whey. This happens when milk turns sour, when acid such as lemon juice is added, or when it is overheated. The word also appears figuratively: blood may be said to have curded in fear or horror, evoking the way liquid thickens and stops flowing. In the kitchen, curded can be either desirable or disastrous. Cheesemakers deliberately curdle milk as the first step in making cheese, while a cook whose delicate sauce has curded faces a ruined dish. Because the transformation is so visible and irreversible, the word carries strong sensory associations of sourness and spoilage. Understanding curded helps readers follow both practical recipes and vivid literary descriptions alike.

Before the word 'curd' existed, English speakers borrowed it from 'crud' — the same root that gives us the word for something disgusting — which is why your cheese and your kitchen grime are distant linguistic cousins.

Etymology of curded
The verb curdle derives from the noun curd, which itself arose in Middle English as a variant of crud, from Old English crudan meaning 'to press or congeal.' Curdled was formed by adding the -le frequentative suffix, giving rise to forms like curdling and curded. The word has been part of English since at least the medieval period, long before modern dairy science explained the chemistry behind it.
