Jam Roly-Poly Calories

Last reviewed: June 21, 2026

Jam Roly-Poly is a classic British steamed suet pudding: a flat sheet of suet pastry spread thickly with raspberry or strawberry jam, rolled into a log, wrapped in foil or a damp cloth, and steamed or baked until the pastry is tender and the jam has softened into a sweet, oozing filling. Traditionally served with a generous pour of warm custard, it is the ultimate British school dinner pudding — nostalgic, warming, and deeply comforting on a cold day.

About Jam Roly-Poly

Jam Roly-Poly appears in Victorian British cookbooks as a classic steamed suet pudding. It was a staple of British school dinners throughout the 20th century, earning the affectionate nickname 'Dead Man's Arm' in school canteens — a reference to its resemblance to a limb when steamed in a cloth. Suet puddings were a British culinary tradition stretching back centuries, valued for their economy and heartiness. The dish fell from fashion in the health-conscious 1980s and 1990s but has enjoyed a nostalgia-driven revival in British restaurants and gastropubs.

Cooking Tips

  • Use a proper suet pastry — butter won't give the same tender, steamed texture.
  • Spread jam generously, right to the edges.
  • Leave a 2cm border when rolling to prevent jam from leaking out.
  • Steam for 1.5–2 hours in a tightly sealed foil parcel for best results.
