Well, this year for our holiday dinner, I finally did it! After a couple of previous experimental attempts at making Yorkshire Pudding (usually on a holiday and always with guests present), I finally got it right! Light and crispy and poofy huge. The biggest contribution to my success this year seems to be the Wondra flour, but using pan drippings and not taking shortcuts by using crisco and beef broth also yielded good results for me. I think cast iron muffin pans would work fabulous, but I'll have to wait to try that experiment until I add to my cast iron assortment.
