Cut away any excess greaseproof paper and tuck the foil underneath. This will ensure that the pudding remains watertight.
Make a handle for the pudding by threading a double length of string through the string already tied around the pudding. Pull it through to the other side and secure.
Place the pudding into a saucepan and fill the water level to half way up the basin. The water level should not drop down to less than 1/4 way up the pudding basin.
Steam for several hours, or as recipe indicates. Top up water when necessary.
When the pudding is steamed, cut the string around the bowl. Gently ease away the paper and foil.
