Cereal first. It’s the level of the cereal which determines the volume of milk required. Think of the milk as a garnish. But it’s something to roll around in your head, like flopping your pancakes on a plate covered in syrup, or depositing a big slice of pie on top of a scoop of ice cream.
I tried it milk first just now on my mini-wheat’s . Was fun and exciting, then turned out normal. vanilla flavor was stronger. Will use when I am running low on milk. Which is now.
