Fair play MM, it is a steak n kidney pud. Pea wet is the green water off mushy peas poured all over chips, as its cheaper. Mungryme is how someone from Wigan sounds saying I'm hungry and clempt is a Wigan word for hungry.
Loads more from the town with almost its own language but i'd better leave it to the Wiggeners to tell us more.
cheers mate ?
