Tips for success:
- Use fresh, not frozen fruit, frozen fruit will melt as it bakes and may make your tarts soggy.
- Don’t let your dough get too warm, cold butter will release steam as it bakes causing the layers to puff up, if your dough gets too warm the butter will melt in the oven instead and your pastry will become tough and rubbery.
- Do not get the egg wash on the edges of the dough, this will adhere the layers of the puff pastry together, preventing them from puffing up.
- Sift the powdered sugar for the glaze, lumps in powdered sugar could cause the glaze to separate.
- Use seasonal fruits, because we can access any type of fruit year-round, it’s easy to forget that fruits grow in seasons. Fruits in season are more flavorful and make for much better tarts, plus it lets you refresh and customize these tarts all year round.
Baking with sourdough discard
When incorporated into buttery pastry, sourdough discard adds a slight tang. Since you’re not using it as a leavener, you can use your discard straight from the refrigerator. There’s no need to feed it or activate it before mixing it into your dough. Older discard will have a tangier, more acidic flavor than a freshly-fed sourdough starter. Both will work for this recipe, you’ll just get a slightly different flavor profile but your bake will still be delicious!

What you need
Sourdough rough puff pastry: Use my recipe for homemade sourdough puff pastry or use store-bought.
Fresh fruit: You can use any type of fruit, here I used a mixture of blueberries, blackberries, and cherries. Don’t use frozen fruit because they will release too much water as they bake and may make your tarts soggy.
Cane sugar: When possible, I like to use cane sugar since it is produced using a more sustainable way, feel free to substitute granulated sugar if that’s all you have on hand
Cornstarch: Helps thicken any juices that come out of the fruits as they bake, you can substitute all-purpose flour if you don’t have any on hand.
Egg: Helps with browning, if you don’t want to use an egg, you can substitute a little bit of baking soda diluted in water.
Powdered sugar: For the glaze, it’s best to sift your powdered sugar for the best results.
Vanilla: Adds flavor to the glaze, substitute lemon juice or almond extract.
