I know this pudding should have been made months and months ago, but
we are suddenly invited to a dinner for 20 people and the pudding that
is awaiting is too small, so I need to make a Very Large one.

Unfortunately I cannot cook it by putting it in a pan au bain marie on
top of the stove because of the size, so thought I might try it au
bain marie in the oven

Anybody got any experience and/or advice.

Thanks enormously.
Cheers
Menno
