Why the Outside of Baked Foods Is Uncooked While the Core Gets Burnt in a Microwave Oven

Understanding the Science Behind Microwave Cooking

Microwave ovens are a handy tool for reheating and melting, but they have limitations when it comes to baking food like pizzas, cookies, or cakes. The key to this phenomenon lies in the way microwaves work: they heat based on the moisture content and do so from the inside out, rather than distributing heat evenly across the entire surface.

Microwaves operate using a specific frequency in the microwave band of radiation. Under normal circumstances, microwaves are low power and non-ionizing, making them safe for use. However, this frequency interacts with water molecules in the food, causing them to vibrate and generate heat. This steaming action tends to cook the food from the inside out, which can result in uneven cooking.

Common Culprits: Oven Temperature and Pan Material

There are several factors that can contribute to the outside of your baked goods being uncooked while the core of the food gets burnt. Here are some insights and solutions from a baking expert:

Oven Temperature

**Oven is too hot or heating unevenly:** If your oven temperature is too high, it can cause the external layers of the food to cook faster than the core. Similarly, uneven heating can result in the same problem. Using a cheap oven thermometer can help you ensure your oven is set to the correct temperature.

Pan Material and Placement

**Dark pan placement or wrong placement in the oven:** Dark-colored pans can absorb heat more quickly, which can cause burning. Additionally, placing baked goods too high in the oven can result in the outside being overcooked before the inside is properly cooked. Make sure to place your items towards the middle of the oven, not too close to the top or bottom.

Recipe Adjustments

**Moisture content in the recipe:** If the recipe calls for a higher liquid volume, the internal pockets of moisture may take longer to heat up uniformly, leading to a burnt core and an undercooked exterior. Adjusting the liquid content or using a lower oven temperature can help balance the cooking process.

solution: Adjusting Conditions for Even Results

Here are some practical steps to ensure even cooking in your microwave oven:

Reduce Oven Temperature

**Reducing the temperature by 25 degrees Fahrenheit:** If the oven is too hot, reducing the temperature can help prevent the outside from burning while the core is still raw. This adjustment can make a significant difference in achieving a better baked result.

Choose Appropriate Pans

**Use light-colored pans or glass/ceramic materials:** Light-colored pans reflect heat more effectively and reduce the risk of burning. If you are using metal, ensure it is safe for use in the microwave and also avoid placing it too close to the top or bottom of the oven.

Conclusion

Baking in a microwave oven can be challenging due to its unique cooking mechanism, but with the right adjustments, you can achieve perfectly cooked baked goods every time. By paying attention to oven temperature, pan material, and recipe adjustments, you can enjoy evenly cooked pizzas, cookies, and cakes that satisfy both your taste buds and your standards.
