About This Recipe
This recipe is a true impromptu—it came about when a host needed to feed surprise guests with minimal fuss. The key is using ready-made tartlets (sand pastry shells) that bake in minutes. The filling combines fresh apple cubes with sour cream, egg, sugar, and a spoonful of jam or preserves, then cooks quickly in the microwave. The result is a light, fruity, not-too-sweet dessert perfect for the holiday table.

Ingredients
- 1 large apple (about 150 g)
- 1 tablespoon lemon juice
- 2 tablespoons sour cream (20% fat recommended)
- 1 large egg
- 2 tablespoons granulated sugar
- Pinch of vanilla sugar or vanilla extract
- 2 tablespoons jam, preserves, or fruit spread (any flavor, e.g., apricot or berry)
- 6–8 ready-made sand tartlets (about 6 cm diameter)
Step-by-Step Instructions
Step 1: Wash and dry the apple. Peel it, remove the core, and dice the flesh into small cubes (about 0.5 cm). Place the cubes in a bowl and sprinkle with lemon juice to prevent browning. Toss gently.
Step 2: In a mixing bowl, combine the sour cream, egg, sugar, and vanilla. Whisk until smooth and homogenous.
Step 3: Fold the diced apples into the sour cream mixture, then add the jam or preserves. Stir until everything is evenly distributed. The jam adds sweetness and depth—choose a chocolate-covered raisins pairing? Actually, fruit jams like apricot or raspberry work beautifully here.
Step 4: Spoon the filling evenly into the tartlets. Place them in a microwave-safe dish. Microwave at full power (800 W) for 3 minutes. Let rest for 30–60 seconds, then microwave for another 1.5–2 minutes. The filling should be set but still slightly jiggly. For precise timing, refer to our best non-toxic immersion blender guide—it's not directly related, but we love kitchen tools that last.
Step 5: Allow the tartlets to cool to room temperature. This helps the filling firm up. Meanwhile, you can prepare a pot of tea or coffee. Want to elevate your coffee game? Check out our best George Howell coffee for a truly exceptional brew.
Step 6: Once cooled, garnish each tartlet with an extra dollop of jam or preserves. This adds a glossy, festive touch. For a more luxurious finish, try a best steam canner if you make your own jams from scratch—but store-bought works perfectly.
Step 7: Arrange the tartlets on a serving platter and serve with tea or coffee. A dusting of powdered sugar or a sprig of mint adds a final flourish. Happy New Year! For more dessert inspiration, see our Catalan sponge cake recipe.
Tips & Tricks
- Use a crisp, tart apple variety like Granny Smith for a pleasant contrast to the sweet jam.
- If your microwave has variable power, adjust the cooking time. The total cooking time should be about 4–5 minutes total, with a pause in between.
- Don't overfill the tartlets—leave a small rim to prevent overflow during cooking.
- For a richer flavor, substitute sour cream with crème fraîche or mascarpone.
- If you don't have ready-made tartlets, you can use puff pastry cups or even mini phyllo shells. For a different texture, try our best food processor for nut butter to make your own nut crusts.
Variations
This recipe is endlessly adaptable. Swap the apple for pear, peach, or even persimmon. Use different jams: cherry, strawberry, or even a best lava flavors inspired reduction? Or go savory: skip the sugar and add cheese and herbs for a quick appetizer. For a boozy twist, soak the apple cubes in rum or Calvados before adding. Pair with a best sweet wine with high alcohol content for a grown-up dessert.
Frequently Asked Questions
Can I make these tartlets in advance?
Yes, you can prepare the filling and assemble the tartlets up to a day ahead. Store them in the refrigerator, but wait to microwave until just before serving. For crispness, reheat in a best air fryer non-toxic for a few minutes.
What if I don't have a microwave?

Can I use a different fruit?

How do I prevent soggy tartlets?
