"This is called 'Real Original' because it is based on the recipe taken directly off the back of a 1950s Chex cereal box. For the more complicated updated recipe, go to Chex Party Mix, which contains pretzels and bagel chips. Oh, and Anthony wrote me as well - he says that margarine is the original, not butter. He says the mix tastes better with margarine. I personally prefer butter, but it's your choice!..."
