I am going to try Rose’s recipe this year, I’ve been making another recipe that uses evaporated milk, but I’d like to try the milk/cream thing this year. Rose says to put the pyrex pie plate directly on the floor of the oven, or on a baking stone. Since my oven is electric, I’d have to use the baking stone option. I’ve never baked anything in a pyrex glass dish directly on a baking stone, so I am hesitant to do this for fear of t he glass breaking. Is this really a safe thing to do? I’d hate number one to have the pie ruined, but worse, the clean up would be a disaster if the pie plate shattered.
