Step 1: Determine your preferred milk:cereal ratio through trial and error.
Step 2: Thereafter, pour all cereal and milk from a measuring cup, thus ensuring accurate cereal and milk quantities.
Step 3: Idc whether you pour milk or cereal first, you do you, but eat it before it gets soggy. Why are you eating your cereal so slowly? Soggy cereal is a crime. If you want to savor your morning (you weirdo, mornings suck) then do so over a cup of your coffee/tea/hot caffeinated beverage of your choice.
