A new word for a lot of Americans will be “stodge”. It’s a word with many negative connotations, but in the case of Jam Roly Poly that’s what it’s supposed to be – a stodgy comfort food designed to deliver calories straight to your waistline. Enjoy!
Preheat the oven to 160c / 315f.
Blend the first 4 ingredients thoroughly. Add the lemon juice to the water and stir into the flour blend until the dough just comes together – it should be slightly sticky, but not wet. With GF flour blends you may need to add a little more water – if so, add it a tablespoon at a time.
Roll the dough out to a half inch / one cm thickness. Try to get it as close to a rectangle as you can. If you’re me, a rough potato shape is the best I can do!
Spread the jam thinly over the surface, leaving an edge about the thickness of the width of your thumb at a long edge. Slowly and gently roll the dough towards the exposed edge, without trying to get it super tight. You want a rough cylinder with a little internal room for expansion. Pinch the cylinder closed at the jamless edge and leave the join up for the moment.
Butter up some baking paper and roll the dough log onto it, join side down. Wrap the dough log loosely with the baking paper, making sure the log is completely surrounded, and tie off the ends with string. Wrap the log up in a tea towel or foil to create a sealed cylinder.
Place the wrapped roly poly in a loaf pan or other convenient heat resistant receptacle, then place the receptacle on a trivet or other support (such as old jam jar lids) into a baking pan. Place the baking pan in the oven and pour boiling water into the baking pan – you want plenty of water in there, but not so much it splashes out of the baking pan. You also don’t want any water entering the loaf pan with the pudding in it.
Bake for 1 hour. Serve cut into slices so that you can see the internal swirl. Cover generously with custard and serve with a nice cuppa tea.
One note, this is not a super sweet pudding. The dough is meant to be fairly plain to allow the jam and the custard to take central stage.
