Tips & Variations
- Use cold butter and pulse gently when making the crust to keep it flaky and tender.
- Add a tablespoon of finely chopped fresh basil or thyme to the filling for a subtle herbal note.
- For a gluten-free option, substitute the all-purpose flour with a gluten-free blend.
- Serve with a dusting of powdered sugar or a few fresh berries on top for added visual appeal.
Storage
Store the tart covered in the refrigerator for up to 3 days. Bring to room temperature before serving for the best texture and flavor. You can also chill it longer for a firmer, more refreshing dessert. Avoid freezing, as the mascarpone filling may separate upon thawing.

FAQs
Can I make the crust without a food processor?
Yes, you can use a pastry cutter or your fingers to work the butter into the flour mixture until it forms crumbs, then mix in the sour cream to form the dough.
What if I don’t have mascarpone cheese?
Cream cheese can be used as a substitute, though the tart’s flavor and texture will be slightly different—less silky but still delicious.
