|Just out of the oven!|
My also-antique bundt pan is coated with Teflon, but it still works. (Note that Teflon is not considered harmful, that's kind of a myth.) The printed book I used is so old that the recipe version there only mentions a tube pan. Bundt pans became popular in 1966, which is probably when I received mine as a gift from my Aunt Bernadine, though she may have given it to me even before that. The app -- being entirely twenty-first century -- says to use a bundt pan, which I did.
I greased the pan with my secret hoard of original Crisco. I use it only for greasing baking pans, so I don't think it will harm us too much even though it's trans fat. I used butter as the shortening in the cake itself -- butter, the great and wonderful and vindicated fat that isn't anywhere near as dangerous as they once told us. Greasing the pan with Crisco does make a very crisp and brown exterior on a cake!
