The memory that serves this topic most is that whenever my family ordered a pizza, what ever remained after the meal was left in the stove until the morning. For breakfast, I would be treated to the savory deliciousness of remembering what was a good night is now to be the start of a good morning. Yet refrigeration of the food detracts from the goodness of it slightly. For me, best bet is to to leave in the box, wait some 12 hours, prepare a plate and enjoy.
Cold pizza is money. Re-heated--poo poo.
