SAVORY ROULADES with Ham & Corn, Creamed Chicken and Smoked Salmon fillings

Mum must have cut this recipe pretty roughly from the The Sun newspaper, her breakfast time reading every morning.  It’s missing a small section, but I think you can work out the ham and corn filling without it.  I’ve never made a roulade using potato, but it would make a nice firm base and Nancy Baldwin’s instruction are very helpful.
