What British dessert is a steamed suet pastry rolled around jam?

Jam roly-poly is the British dessert made from steamed suet pastry rolled around jam.

The pudding consists of a suet-based dough spread with jam, rolled into a cylinder, and steamed until cooked. Raspberry jam is a familiar filling, although other jams can be used. It is traditionally served hot, often with custard.

The dessert is sometimes nicknamed “dead man’s arm,” a reference to its shape and its historical method of being wrapped before steaming. Older recipes describe cooking it in a cloth, while modern versions are often steamed in foil or baking parchment.

Jam roly-poly belongs to the family of British steamed puddings, alongside spotted dick and treacle sponge. Unlike spotted dick, it is defined by its rolled form and jam centre rather than dried fruit mixed through the dough.
