I have been using Chicago Metallic popover pans, both the mini and standard size, for years. Always have performed very well, producing airy, golden popovers and Yorkshire pudding with minimal clean-up. I like the minis because I can make 12 at one shot rather than having to use two of the standard pans. I always have at least two of the minis and standards so that, whichever I am using, as soon as one comes out of the oven, the next goes in on a rotating basis. Around my house, anything less than several dozen puddings with a prime rib dinner is considered not only insufficient but also an insult. Love those pans.
