Jam roly-poly, shirt-sleeve pudding, dead man's arm or dead man's leg is a traditional British pudding probably first created in the early 19th century. It is a flat-rolled suet pudding, which is then spread with jam and rolled up, similar to a Swiss roll, then steamed or baked. In days past, Jam Roly-Poly was also known as shirt-sleeve pudding, because it was often steamed and served in an old shirt-sleeve, leading to the nicknames of dead-man's arm and dead man's leg. In the past it was known as roly poly pudding.
