Ingredients:
- 6 Tbsp (85 g) Unsalted Butter, plus extra for greasing (for crust)
- 1 ½ cups (185 g) All-Purpose Flour (for crust)
- 2 Tbsp (25 g) Granulated Sugar (for crust)
- ¼ tsp (1 g) Fine Sea Salt (for crust)
- 3 – 5 Tbsp (45 – 75 ml) Ice Water
- 1 Large Egg Yolk (for the blind bake wash)
- 3 large (Approx. 650 g) Firm Dessert Apples, Peeled, cored, and diced
- 1 ½ cups (175 g) Fresh or Frozen Cranberries
- ½ cup (100 g) Light Brown Sugar (for filling)
- 2 Tbsp (15 g) Cornstarch or Plain Flour (thickener)
- 1 tsp (5 g) Ground Cinnamon
- ½ tsp (2 g) Ground Nutmeg
- 1 tsp (3 g) Orange Zest
- ½ cup (60 g) All-Purpose Flour (for topping)
- ½ cup (45 g) Rolled Oats (not instant)
- ¼ cup (50 g) Light Brown Sugar (for topping)
- 4 Tbsp (56 g) Cold Unsalted Butter, Cut into small cubes (for topping)
- Pinch (1 g) of Salt (for topping)
Instructions:
- Brown the Butter: Melt the 6 Tbsp (85g) butter in a saucepan over medium heat. Continue cooking, stirring frequently, until the milk solids settle, toast, and turn a nutty brown colour (about 5–7 minutes). Remove immediately and transfer to a heatproof bowl to cool slightly.
- Mix Dry Ingredients: In a large bowl or food processor, combine the flour, sugar, and salt for the crust.
- Incorporate Butter: Pour the warm (but not hot) brown butter into the dry mixture. Mix until crumbly—the texture should resemble coarse cornmeal.
- Add Liquid: Add the ice water, 1 tablespoon at a time, pulsing until the dough just comes together. Do not overwork.
- Chill: Form the dough into a disc, wrap tightly in plastic wrap, and chill in the refrigerator for a minimum of 60 minutes.
- Blind Bake: Preheat oven to 375°F (190°C). Roll out the chilled dough and press it into the 9-inch tart tin. Prick the bottom with a fork, line with parchment paper, fill with baking weights, and bake for 15 minutes.
- Egg Wash: Remove weights and parchment. Brush the base lightly with the egg yolk mixed with a splash of water (this helps waterproof the crust). Return to the oven for 5 more minutes until lightly golden. Set aside.
- Prepare Filling: In a large bowl, combine the diced apples, cranberries, brown sugar, cornstarch, cinnamon, nutmeg, and orange zest. Toss well to ensure the fruit is evenly coated with the thickener and spices.
- Make the Crumble: In a separate medium bowl, combine the flour, oats, brown sugar, and salt for the topping. Cut in the cold, cubed butter using your fingertips until the mixture resembles coarse, uneven pebbles.
- Assemble: Pour the fruit filling into the blind-baked crust, ensuring the fruit is distributed evenly.
- Top and Bake: Scatter the oat crumble topping over the fruit filling. Bake for 50–55 minutes at 375°F (190°C), or until the crumble is deep golden brown and the fruit juices are bubbling vigorously.
- Cool: Allow the tart to cool completely on a wire rack before serving (at least 2 hours). This is crucial for the filling to set.
