Here’s the big question everyone asks: How long do I actually boil this stuff? The official answer from health experts is simple. You need to bring the water to a full, rolling boil—not a timid little simmer, but a vigorous, angry boil that looks like a tiny storm in your pot. Then, let it roll for one full minute. That’s it. Sixty seconds. You can literally count it out, maybe while doing a little victory dance.
But wait—there’s a twist, because of course there is. If you live above 6,500 feet in elevation (hello, mountain friends!), the boiling point drops, and water boils at a lower temperature. That means you need to boil it for three full minutes instead of one. Why? Because lower temps mean it takes longer to kill the nasty critters. So adjust accordingly, or your water might still be plotting against you.
What About Kettles? Please Tell Me Kettles Count
Yes, electric kettles absolutely count! Most kettles will bring water to a rolling boil automatically, and that’s perfect. Just let it sit for a minute after the switch clicks off. But here’s a pro tip: don’t use a kettle that automatically shuts off at a lower temperature, like those fancy variable-temp ones. You want the full, crazy, sputtering boil. Otherwise, you’re basically just giving your water a warm bath, and that won’t cut it.
And while we’re at it—microwaves? Sure, but they’re trickier. Water in a microwave can superheat and explode in your face (dramatic, but true). So if you use a microwave, heat it in a microwave-safe container and add a wooden chopstick or a ceramic mug to prevent that. Then, once it bubbles violently, let it sit for a minute. Just be careful when you pull it out. Nobody needs a trip to the ER on top of a boil advisory.
