As children in the 50s we bought paper bags of Kali (my mouth's puckering up at the thought of its sharpness now!) and Spanish (chewy roots or twig-like pieces) in Rochdale, too, but at the sweet shop, not the toffee shop, Elaine.
Toffee was sold on the market and was displayed in shallow oblong tins. It had to be broken up with a special hammer. I've still got an old one in my kitchen drawer, and very handy it is, too, for all kinds of jobs. The salesman's cry of "Home made Toffee" rang out across the market and attracted us children, who loved to find the weirdest shaped pieces, especially large ones which would stretch your mouth and face into funny shapes. Really yummy was his treacle toffee.
