"Pudding" in British English is a genuinely broader term than in American English — it refers to dessert generally, not just the specific creamy, custard-style dish Americans mean by "pudding" — and British regional pudding traditions cover a surprisingly wide range of formats.

Clearing up the terminology first

In Britain, "pudding" is often used as a general synonym for dessert course, regardless of what the actual dish is — a British person asking "what's for pudding?" is simply asking what dessert is being served, which can genuinely confuse American visitors expecting the word to refer to one specific creamy dessert.

Regional puddings worth knowing

Why steamed puddings specifically developed as a category

Steamed puddings — a genuinely distinct British cooking method compared to baking — developed partly out of historical kitchen practicality, since steaming didn't require a dedicated oven the way baking did, making it accessible to households without reliable oven access in earlier periods of British food history.

Ask a British person "what's for pudding?" and they're not necessarily asking about custard — they're just asking what dessert is.

A practical tip

If a UK menu lists a "pudding" section, expect it to cover the full range of desserts, not one specific dish — the term functions as a category header, and the actual options underneath it can range from ice cream to a steamed suet pudding.
