How do you convert a recipe that fits into 9 inch tart pan to 11 pan?

Understanding the Difference

* Area: A 9-inch tart pan has a smaller area than an 11-inch pan. To figure out the difference in area, you'll need to calculate the area of each circle:

* 9-inch pan: Area = πr² = π * (4.5)² ≈ 63.62 square inches

* 11-inch pan: Area = πr² = π * (5.5)² ≈ 95.03 square inches

This means the 11-inch pan has roughly a 50% larger area than the 9-inch pan.

Adjusting the Recipe

1. Filling: Since you have more space in the larger pan, you'll need to increase the amount of filling. Here's how:

* Simple increase: You can simply increase the filling by 50% to match the increased area.

* More precise: If you want to be more precise, consider the recipe's instructions. If it calls for a specific depth of filling, you can calculate how much more filling you need to achieve that depth in the larger pan.

2. Crust: You may need to adjust the crust recipe as well. Here are a few approaches:

* Increase proportionally: Increase the crust recipe by 50%.

* Keep crust the same: If the recipe already calls for a thin crust, you can keep the original recipe and use the extra space in the pan for a larger filling amount.

* Roll out a larger crust: You might want to roll out the crust into a larger circle to fit the 11-inch pan. You can do this by increasing the original crust recipe by about 25% to 30%.

Important Considerations

* Baking time: Since you have more filling and a potentially larger crust, you might need to increase the baking time. Start by checking the original recipe and adjust it as needed.

* Cooking temperature: You may not need to change the baking temperature.

* Don't overfill: Even though you'll have more space, don't overfill the pan. The filling should be level with the top of the crust, but not overflowing.

Example

Let's say your original recipe for a 9-inch tart calls for:

* 1 cup of filling

* 1 crust recipe

For an 11-inch pan:

* Filling: Increase the filling by 50% to 1.5 cups.

* Crust: You can either increase the crust recipe by 50% for a thicker crust or keep the original recipe and use the extra space for more filling.

* Baking Time: Check the original recipe's baking time and increase it slightly.

Remember: It's always a good idea to start with a slightly smaller amount of filling and then add more if needed. This will help prevent overfilling and ensure a successful tart.
