Answer: Milk
Explanation: Having the milk go in first will allow the cereal to be more crunchy when first pouring the milk, but having the cereal a little bit extra soaked may be tastier for some people, but not me. The crunchier the cereal is the better. Although I believe both ways are okay, having crunchy cereal with a side of milk on the spoonful is a great way to start a morning.
