Before you boil something, make sure that you roast it.
Why would you roast something before you boil it? Because that something is tea! Or maybe coffee. Tea leaves and coffee beans are roasted before they're boiled.

Smell the wafting scent of roasted centaur as you sip on your freshly-roasted tea.
