Frequently asked questions
What is the fan/convection oven adjustment?
Fan (convection) ovens circulate hot air, cooking food more evenly and efficiently. They typically cook 20°C (about 35°F) hotter than conventional ovens. Always reduce the temperature by 20°C when converting a recipe written for a conventional oven to a fan oven, or reduce cooking time by 10–15%.
How do I convert Gas Mark to Celsius?
Multiply the Gas Mark by 14 and add 121: °C ≈ (Gas Mark × 14) + 121. Gas Mark 4 = (4×14)+121 = 177°C ≈ 180°C. This calculator handles all conversions automatically.
