What food would you say is your specialty?

My speciality‘s messing up
I’ve done it once again!
Yet again I spoiled the bread
I thought I‘d added yeast.
It doesn’t look as if I did
Or maybe not enough.
It’s getting well beyond a joke
I know my wife won’t laugh!
I make mistakes,
keep losing things
I think I always have
But worryingly
It’s getting worse
I’m not right in my head.
