Mix flour and sugar, eggs and butter
Cocoa, lemon or vanilla
Beat and bind them well
And even then.
If you really tried
You could find a way
To separate them out again.
That’s a mixture.
But put it in the oven:
Apply heat
And chemical reactions will take place
You’ve got yourself a compound there
And things will never be the way they were
The only thing that’s left to do
Is eat.
