Sunday roast problem

I have absolutely no answer. I just wanted to bond with another flat pudding maker. Both grandmothers and mother made fantastic puds, and I am no slouch as a cook generally.
But the kitchen goddess deserts me whenever the words 'Yorkshire Pudding' are uttered. I have strayed from my mum & gm's recipe to try to get an answer, and have tried just about every trick I have ever come across. I shall monitor this thread in case of new ones.
And no, I daren't try Aunt Bessie's. Every ancestress ever would come to haunt me!

My son does a superb Sunday dinner and he cooks the Yorkshires whilst the meat is roasting, rather than having to put the heat up towards the end. They stay hot in the second oven. So this could account for the early time.
We eat at 1 pm on Sundays.

I’m just puzzled at someone having a roast dinner at 12.00.

Why?

Some of us like to eat early, and perhaps the OP is having afternoon tea later?

Have you used the wrong flour?

I quite like the flat puddingy effect of using SF flour occasionally.

Auntie Bessies ?

Perhaps EvaDarcy is in a time zone two hours ahead MerylStreep!

DD was cooking hers when she phoned at 9 am today (our time).

Check your oven temperature. You can buy oven thermometers.
