"Recipe for Disaster" (Entry 9)

The time. Was Christmas.
It was her mother's and her mum's
mother's recipe before.
Used for decades,
Tried and tested.
Loved, each year, by all
in the family, they'd jaw.
So when she made it...
and it did not work.
It did not rise,
and taste? Well... abhor!
She cooked it again,
then again, and again
and each more awful,
much worse was the chore.
She glared at the recipe,
vowed Nigella was in,
and her mother's? The door!
