"The four long house tables were laden with tureens of porridge, plates of kippers, mountains of toast, and dishes of eggs and bacon, beneath the enchanted ceiling (today, a dull, cloudy gray)" (Chamber of Secrets 86).
Kippers, in case you didn't know, is (according to wikipedia, that pinnacle of source materials) a whole herring. A small, oily fish, that has been split from head to tail, gutted, salted or pickled, and cold smoked. They are commonly eaten in Britain for breakfast.
I will keep my opinions on kippers to myself. Suffice to say, we will not be preparing them today.
