There are some tricks to making your popovers perfect.
If you don’t have the popover pan, it is OK to use a muffin pan.
The cups are smaller so they don’t need to be in the oven as long.
No reason to purchase a special pan.
Try and get your ingredients to room temperature.
Always use all purpose flour, unless you like to eat hockey pucks.
Make sure your cups are greased, you don’t want those puppies sticking.
I also preheated my pan while I preheated my oven.
Last but not least, I know you will be tempted, please, please, please, do not open the oven door. Use the light and peek in through the glass.
When are they done?
When they are golden brown and delicious!
