I had a pang of nostalgia the other day for a leek pudding and searched online for a recipe as there was nothing in any of our books by Sir Nigel of Slater that showed that he knew what to do. The online recipes I found all recommended boiling the pudding for 2-3 hours. Boiling for 2-3 hours? That's not a pudding, that's a hot wash for the sheets.
Anyway, I've now found this intriguing recipe which at least comes from the north-east so I'm trusting that the guy knows what he's talking about. I'll report back in due course.
