Making foil pan molds per Maida Heatter's recipes
I loved the Buttermilk Lemon Bundt cake recipe from Food52 so I ordered an old volume of Maida Heatter's recipes. She makes foil pan molds from the outside of the baking pan, then inserts it in the pan. I assume it's to prevent sticking or easy removal of cookies. Is this necessary in the age of silicon mats and parchment paper?
