Jam roly-poly, known as Suety Jack in the Potteries, is made with suet pastry and may be boiled or baked. Lady Jekyll, writing in 1922, recommended the use of stoneless damson or plum jam for baked suet roly-poly puddings, and certainly the bland pastry needs a dark sturdy jam as contrast. She also suggested putting the pudding on a baking tin greased on one side only, and tilting the tin inside the oven to keep the required ‘roly’ shape and prevent the spreading of the pudding.
Stir together the flour, salt and suet and mix to a firm dough with water.
Roll out to a rectangle 8 x 12 in (20 x 30 cm) and spread thickly with the jam. Roll up firmly and put onto a greased baking sheet.
Bake at 425°F/220°C/Gas Mark 7 for 40 minutes until golden brown.
