Why didn’t my Yorkshire pudding rise?
Almost always one of these: the pan and fat were not hot enough, you opened the oven too early, or your batter was too thick. Make sure the fat is shimmering hot in the pan before you pour, and do not crack the door for at least 20 minutes.
Do I really have to rest the batter?
You will still get a pudding without resting, but a 20 to 30 minute rest improves rise and texture. If you want to rest it longer than about 30 to 60 minutes, pop it in the fridge for safety, then bring it back toward cool room temp and whisk again right before pouring.
What sausages should I use?
British bangers are traditional, but any pork sausage works. Choose sausages that are not too lean because a little fat helps with flavor and moisture. If using chicken or turkey sausage, add a touch more fat to the pan.
Can I make it without a cast iron skillet?
Yes. Use a metal baking dish, a roasting pan, or an oven-safe stainless skillet. Glass or ceramic can work, but they do not deliver the same immediate heat sizzle, so the rise is often a little less dramatic (and they can be more prone to temperature shock). If you use them, preheat the dish longer and expect a slightly gentler puff.
Can I make the gravy ahead?
Absolutely. Make it up to 3 days ahead, refrigerate, and reheat gently with a splash of broth or water to loosen.
Is it supposed to be a little soft in the middle?
Yes. The goal is crisp, browned edges with a tender, soft center. If the center is raw and sloshy, it needs more time in the oven, or your pan was too full.
