Theme for big out of state gathering is to bring local delicacy/fave. Can be anything from app to entree/dessert or side. Can be reheated, as it's a 2-3 hour drive, but that works better for, say a takeout tray of eggplant parm than a Kinchley's Pizza. Examples? CT couple is bringing kielbasa from great old Polish delis; Brooklyn couple bringing Syrian foods from Atlantic Ave.
So I need to represent the best of Northern NJ/Bergen Cty to out of staters.
I was thinking B&W crumbcake. Ideas?
