@mckenzie,
Making cinnamon toast on Sunday nights was one of my childhood chores.
I mixed butter, sugar and cinnamon in a bowl and put bread on a baking sheet (covered with a tea towel).
Then Ed Sullivan started.
During the first commercial I spread the butter/sugar/cinnamon mixture on the bread and put it in the oven on 200 or maybe 250 (it's nearly 50 years ago so I'm not exactly sure). Second commercial, I went to the kitchen, pulled out the cinnamon toast, cut it into strips and put it on plates for snacks during the second part of the show.
Good memories of the bubbling toast topping
