In Japan, people often boil water for ocha (tea) without a second thought—it’s just routine. In Mexico, street vendors boil water for aguas frescas on the sidewalk, and tourists watch in awe. Meanwhile, in the U.S., we’ve convinced ourselves that bottled water is safer, even though a kettle and a stovetop do the same job for pennies.

Fun fact: The ancient Greeks boiled water for wounds and drinking. Hippocrates himself was a fan of the “strain and boil” method. So you’re in good historical company, even if your pot is stainless steel.

Practical Tips for the Modern Boil

Tip one: Don’t waste energy boiling more than you need. A kettle is faster than a pot, and a lid speeds things up by trapping heat. Tip two: Let the water cool naturally. Pouring boiling water into a glass jar can crack it—ask me how I know. Tip three: If you’re boiling for taste, let it sit for a minute after boiling to release dissolved oxygen. That flat taste? It’s real, and it’s from over-boiling.

For an easy upgrade, add a slice of lemon or a pinch of salt once it’s cool—it masks the “cooked” flavor. Or just make tea. Tea solves everything.
