The prepared basin (with plenty of golden syrup!)
I don't have a steamer, so I used my big cast iron pot, scrunched up some tin foil so that the basin wouldn't touch the bottom of the pan
When cooking the boiling water came half way up the side of the pudding basin.
All tied up. I watched a video on YouTube on how to do this before I did it!
The finished product. Despite my excessive greasing, the top still stuck a bit.
