"Backe, backe Kuchen,
Der Bäcker hat gerufen.
Wer will guten Kuchen backen,
der muss haben sieben Sachen..."

Funny nice and popular german's song for children :)
It means:
"bake bake a cake,
the baker said,
who wants good cake baking,
must have seven things..."

I think I need to put one more ingredient - polymer clay! :) When you forget the receipt - just make a cake from FIMO! How do you think?
