Oven Conversion
Fan Oven Conversion
Fan ovens usually cook faster and distribute heat more evenly. The common rule is to reduce conventional settings by about 20°C (or 25°F), but timing and recipe type still matter.

What Matters for This Conversion
- - Use the 20°C reduction rule as a baseline.
- - High-sugar and delicate bakes may need extra care.
- - Check doneness early because airflow can accelerate browning.
FAQ
Is fan oven always 20°C lower?
It is a good baseline, not an absolute for every recipe.
Do baking times also change?
Often yes. Start checking 5-10 minutes earlier.
Why does fan heat brown faster?
Forced air increases heat transfer at the surface.
Does this apply to all foods?
Most baked goods benefit, but very delicate items may need additional tuning.
