How do you prevent jam from leaking out of small tarts while baking in oven?

Here are some tips to prevent jam from leaking out of small tarts while baking in the oven:

Before Filling:

* Use a good quality, thick jam: Thicker jams are less likely to run. Avoid using jams that are very runny or watery.

* Chill the jam: Place the jam in the refrigerator for about 30 minutes before filling the tarts. This will help thicken it slightly.

* Don't overfill: Leave a small space (about 1/4 inch) between the jam and the top of the tart crust. This allows room for the jam to expand as it heats.

* Use a piping bag: If you have one, pipe the jam into the tart shells for a neat and even filling. This helps prevent any overflow.

During Baking:

* Bake at a lower temperature: A lower oven temperature (around 350°F/175°C) will give the jam more time to set without bubbling over.

* Bake for a shorter time: Start with a shorter baking time and check the tarts regularly. They may be done sooner than you think, especially if you're using a smaller tart size.

* Use a baking sheet: Bake the tarts on a baking sheet lined with parchment paper to catch any potential spills.

Other Tips:

* Use a high-quality tart pan: Make sure your tart pan is in good condition and not warped or cracked. This will help ensure the crust bakes evenly.

* Chill the filled tarts: If you have time, chill the filled tarts in the refrigerator for 30 minutes before baking. This will help the jam set slightly.

* Don't overmix the dough: Overmixing the tart dough can make it tough, which can lead to cracks and potential leaks.

After Baking:

* Cool completely: Let the tarts cool completely before serving. This will give the jam time to set properly.

* Top with a glaze: If you're concerned about leaks, you can brush a thin glaze (like a simple syrup or a glaze made with lemon juice and powdered sugar) over the cooled jam. This will help to seal it in.

With a little practice and these tips, you can prevent jam from leaking out of your small tarts and enjoy delicious, perfectly baked treats.
