First, grab a pot and fill it with about four cups of water. This is not the time for cold tap water straight from the pipes of mystery. Use filtered if you can, because no one wants iced tea that tastes like it was filtered through a gym sock.
Bring that water to a rolling boil. A rolling boil, people—not a sad little simmer that looks like it’s having an existential crisis. When the water is dancing aggressively, turn off the heat.
