Worked example

The packet says 400°F for 20 minutes.

  1. Take 36°F off the temperature: 400 − 36 = 364, which rounds to 365°F on the dial.
  2. Take 20% off the time: 20 × 0.8 = 16 minutes.
  3. Start checking a couple of minutes early, at about 14 minutes.

400°F is about 204°C. If the recipe is American and doesn't mention a fan, it's probably a conventional oven.

Foods often cooked at 400°F

  • Fries and potato wedges
  • Chicken wings
  • Roast vegetables
  • Salmon fillets

If the packet's 400°F is for an oven without a fan, switch the converter to Conventional.

For when to turn and how to tell it's done, see the guides for chips and fries, chicken breast and frozen food.
