What am I doing wrong? my popovers won't pop?

I’v never made them, but when you put them in was the cooker hot enough?

Was the oven hot enough? Is your baking powder fresh?

Here is an article with some tips on popover making.

Much to my wife’s chagrin, I have the OPPOSITE problem.

Make sure your oven is preheated to 425 degrees, my recipe says not to overmix, are your eggs fresh?

tried it with cold oven, and preheated oven. hand mixed one time and used mixer other time. I used to make them all the time when I was a kid and never had this problem! thanks evabody wish dear old mum was alive

Does your oven have an upper heating element? Popovers need to be heated only from the bottom, so if the oven has an upper heating element, you should take it out.
