Pastry Tips for Flakiness: The key to a flaky pastry is keeping the butter cold throughout the process. Grating the butter into the flour helps to distribute it evenly without overworking the dough. Once grated, handle the dough as little as possible with your hands to prevent warming the butter.
The folding method used here is similar to laminating dough (like puff pastry), helping to create layers without the need for extensive rolling and folding.
Chilling the Dough: Allowing the dough to chill for at least 3 hours (or overnight) is crucial for the flour to fully hydrate and for the gluten to relax. This step makes rolling easier and ensures a tender, crisp crust.
If you’re in a hurry, you could make the pastry the night before or even freeze it for later use. When freezing, thaw the dough overnight in the fridge before using.
Draining Tomatoes: Tomatoes contain a lot of water, which can make the galette soggy if not properly prepared. By slicing and salting the tomatoes in advance, you encourage them to release excess water. Blotting them with paper towels further reduces moisture.
Rustic Appearance: Don’t worry about the galette being perfectly round or the edges looking flawless! The beauty of a galette is in its rustic charm—it’s meant to look homemade and organic, with folds that naturally occur as you pleat the dough.
You can substitute peaches with nectarines. Fresh herbs like basil or thyme could also complement the sweetness of the peaches and tomatoes.
