If I was ELI5, I would say the steel is like pancake batter, but you’re not sure who made it or what’s in it.

So you make a small pancake and taste it. From there you can add water, milk, eggs, salt, flour or if you want them to be super special, chocolate chips! Make another small one, taste it, and if it’s good, make the rest of the batter into pancakes!

Same with the steel. Test a little bit, then add whatever kinds of other steels or elements you need to make the steel perfect for what you need it for!
