title: "Do You Need an Oven Thermometer?"
lead: "Worth it if you bake and results matter — home ovens routinely run 15-25 °C (25-50 °F) off the number on the dial, and a cheap hang-in thermometer is the only way to see the real temperature. Skip it if you mostly roast and reheat, where being a little off changes nothing."
recommendation:
  name: "A hang-in oven thermometer if you bake — skip it if you only roast and reheat"
  reason: "The dial sets a target, not the truth: most home ovens are miscalibrated by 15-25 °C and swing above and below it as the element cycles, which is exactly why one cake browns and the next stays pale at the 'same' setting. A standalone oven thermometer that hangs from a rack costs little and shows the oven's actual temperature, so you can adjust the dial or move the rack — the cheapest single fix for inconsistent baking. It is a different tool from an instant-read food probe: the probe measures the food's core, the oven thermometer measures the air around it. If your oven only roasts vegetables and reheats leftovers, precision doesn't matter and you can skip it; bakers should own one. Put it where you bake — middle rack, toward the front — and read it after a full preheat."
