Howard Johnson's Ice Cream used to be available at the grocer's. I loved their pistachio flavor. They had other frozen items. I loved their croquettes. And something called Toasties or like that. It was a frozen, cooked corn meal item in the shape of a Pop Tart. You put it in the toaster and out came a hot, toasted corn meal muffin-tasting food. It was delish with butter.
In the early '60s my grandparents bought us a milk shake maker. It was a tall cup with a lid and it looked like a rocket ship. You added a powdered flavor packet, milk and ice and shook it for your own personal milk shake. They always gave us stuff mom would never buy for us.
