So requirements are:
It needs to be big enough for 8 people!
I think it needs to be stainless steel, ceramic won't work on stove top and cast iron is too heavy.
Suitable for induction
Budget not really a constraint, it's a lifetime purchase...so quality is important.
So far this Aga buffet pan comes closest - but would love to see other ideas, hear your comments before I make the final decision.
