So I did Yorkshire Puddings with my roast beef on Sunday. I used my Jamie Oliver recipe which has always given great results. I followed the recipe to the letter. They didn't rise.
The only thing was my flour turned out to have gone out of date November 19 (yikes) but we are shielding so couldn't get fresh supply.
Am I right in thinking that the past it flour would have scuppered the Yorkshires?
