साइज मैटर्स

गलत पैन साइज सबसे आम बेकिंग गलती है। 9-इंच राउंड पैन की रेसिपी 7-इंच में ओवरफ्लो करेगी। स्क्वायर 8-इंच = राउंड 9-इंच (~400 cm²)।

स्वैप नियम

छोटे पैन: मात्रा 25% कम करें। बड़े पैन: तापमान 10°C कम करें और पहले चेक करें।

⚡ CalcWolf Insight

A 10-inch pan has 23% more area than a 9-inch pan, not 11%. People assume the difference is proportional to diameter, but area scales with the square of the radius. This is why your cake overflows when you go "just one inch smaller."
