Butter can not be made from dried milk.
Neither. Milk is an input for butter. One does not use milk on toast instead of butter which would make it a substitute. Nor does one always eat milk with butter which would make it a complement.

MILK
Butter is made from cow's milk. Pig's milk is only used to feed baby pigs.
Since butter is about 80% fat and whole milk is about 3.25% fat, you can get 0.039 liters of butter from 1 liter of milk. Most people make butter from cream, which is about 40% fat.
To make butter from milk, you need to separate the cream from the milk by letting it sit and then skimming off the cream. Then, you can churn the cream until it thickens and separates into butter and buttermilk. Finally, you can strain and wash the butter to remove any remaining buttermilk.
