In the United States, pudding means a sweet, milk-based dessert similar in consistency to egg-based custards, instant custards or a mousse, often commercially set using cornstarch, gelatin or similar coagulating agent. These puddings are known in some Commonwealth countries as custards (or curds) if they are egg-thickened, as blancmange if starch-thickened, and as jelly if gelatin-based. Pudding in America may also refer to other dishes such as bread pudding and rice pudding, although typically these names derive from their origin as British dishes.
Is that something Americans eat?
