Yorkshire's looking good. My wife has been making it for years with a recipe from a lady in BC that runs a B&B. I just asked her what she does and here's some tricks.
- Oven 425 - 450°C (we use 425 as convection)
- Bacon Grease in each baking tin ~ 1 tsp each one
- Get the bacon grease literally "smoking hot" and make sure to turn your fans on high. Fire alarm in the house will sound if not
- Keep the mix and all mixed ingredients at room temp
- when the grease is smoking, put the mix in each cup immediately. I tried to do it myself but couldn't hold a candle to my wife. For every 1 I did she has 5 done.....you still want it smoking when adding mix
- 20 - 25 mins
Hope any of these "secrets" I just groomed from my wife helps you in your recipe! Great looking food you have going
