Popovers Not Popping

RICHARD QUESTIONRose, I have tried your Butter Popover (page 178 of The Bread Bible) recipe three times and for the life of me I cannot get the popovers to rise. They are tasty, for sure, but puffy? No. Your directions have been followed to the letter (including using Wondra), but to no avail. Thanks for any insight you can offer. ROSE REPLY It seems like a physical impossibility that the popovers aren't rising. Could your oven be off? is the fat in the pan getting really hot before pouring in the batter? Try switching to the all-purpose bleached flour suggested on page 180. the popovers will be less tender but they are sure to pop.
