If you cook something at 425 degrees instead of 350 how much time would should it?

You can't just calculate the time reduction by a simple ratio. Here's why:

* Heat Distribution: Higher temperatures create more intense heat, but they might not distribute evenly throughout the oven. This can lead to uneven cooking.

* Food Type: Different foods respond differently to heat. Some benefit from a higher temperature (like a crispy roast), while others need a gentler approach (like a delicate cake).

* Oven Variations: Ovens vary in how they maintain temperature and distribute heat.

Instead of a simple calculation, here's a better approach:

1. Consult the Recipe: Always check the recipe for specific instructions and recommended temperature.

2. Adjust Time Carefully: A general rule is to reduce the cooking time by 25% when increasing the temperature by 75 degrees. So for a 425 degree recipe, you might aim for 75% of the 350 degree recipe's time. But this is just a starting point.

3. Check Doneness: The best way to know if your food is cooked is to check it using a thermometer or by other methods (like poking a cake with a toothpick).

Example:

* Original Recipe: Chicken breasts at 350 degrees for 30 minutes.

* Adjusted Time: Reduce the time by 25% (30 minutes * 0.25 = 7.5 minutes). New time is 22.5 minutes.

* Check Doneness: Use a meat thermometer to ensure the chicken reaches an internal temperature of 165 degrees Fahrenheit.

Remember: Cooking is an art, not a science. Experiment with adjustments, observe your food, and don't be afraid to adjust the cooking time as needed.
