Quick summary
“A warm oven-baked dessert where sliced peaches and fresh blackberries cook until they form a bubbling, caramelized syrup with brown sugar. Covered with a generous layer of rustic oat flakes, butter, and cinnamon crumble.”
What you need to know
- The flour and lemon juice added to the fruits thicken the natural juices, creating a rich caramel.
- The cold cubed butter incorporated into the oats and flour ensures a crispy and grainy topping.
- The oven time of 45 to 55 minutes at 190°C browns the top while the fruit filling bubbles at the edges.
Ingredients
Main
- large, ripe, peeled and sliced Fresh peaches (or frozen)
- cups Fresh (or frozen) blackberries
- cup Light brown sugar (for the filling)
- tablespoon All-purpose flour (for the filling)
- tablespoon Fresh lemon juice
- teaspoon Pure vanilla extract
- teaspoon Salt (for the filling)
- For the Crispy Topping (Double):
- cups All-purpose flour
- cups Rolled oats (thick)
- cup Light brown sugar (for the topping)
- cup Granulated sugar
- teaspoon Ground cinnamon
- teaspoon Freshly grated nutmeg
- teaspoon Salt (for the topping)
- cups (250g) Unsalted butter, cold and cubed
- To serve:
- Good quality vanilla ice cream
- English cream or whipped cream
Instructions
Principal
- Preheat the oven to 190°C. Lightly grease a 23x33 cm baking dish. This is the first step to ensure even cooking of your crisp, making it easier for the fruits to bake and the caramel to bubble without sticking excessively. A well-prepared base is crucial.
- In a large bowl, combine the sliced peaches and blackberries. Add 1/2 cup brown sugar, 1 tablespoon flour, the lemon juice, vanilla, and 1/4 teaspoon salt. Gently mix until the fruits are well coated, forming the delicious filling. Set aside while preparing the topping.
- For the crispy topping, in another large bowl, mix the wheat flour, oats, both measures of sugar (brown and granulated), cinnamon, nutmeg, and 1/2 teaspoon of salt. This is the base for our generous and flavorful topping. Make sure all the dry ingredients are well combined before adding the butter.
- Add the cold, cubed unsalted butter to the dry topping ingredients. Use your fingers, a dough cutter, or a food processor (pulsing briefly) to incorporate the butter. The goal is to form a texture of large, irregular crumbs. The professional technique is not to overprocess, keeping the butter cold to ensure crispiness. In simple terms: crumbs, not a homogeneous batter.
- Pour the prepared fruit mixture into the greased baking dish, spreading evenly. Then, distribute the crunchy topping generously over the fruits, covering the entire surface. Remember, we are making a 'double crispy', so don't skimp on the topping. A thick layer ensures the desired texture after baking in the oven.
- Bake in a preheated oven for 45-55 minutes, or until the fruits are bubbling and tender, and the topping is golden and crispy. The most common mistake is not baking long enough, resulting in hard fruits. The irresistible smell that will invade your kitchen will indicate that it is almost ready. Serve with love and ice cream.
Chef's tips
- Use ripe, firm peaches that have been peeled so the wedges hold their texture without breaking down into a purée.
- Do not mash the topping farofa into a continuous dough; leave pieces the size of peas to give crunchiness.
- Let the crumble cool for 15 minutes before serving so the fruit syrup thickens in the dish.
Variations
- Add 1/2 cup of pecans or chopped nuts to the oat farofa to reinforce the crunchiness of the top.
- Add 1 coffee spoon of fresh grated ginger to the fruits for a citrusy, spicy aromatic touch.
- Serve with a scoop of good-quality vanilla ice cream or warm homemade custard.
Substitutions
- The fresh peaches can be replaced with firm apples, pears, or sliced fresh plums.
- Fresh blackberries can be swapped for raspberries, fresh blueberries, or chopped strawberries.
- Thick rolled oats can be replaced with traditional rolled oats or almond flour.
How to store
Store in a platter covered with plastic wrap in the refrigerator for up to 4 consecutive days. To reheat and restore the crispy texture of the oat topping, place in the oven at 170°C for 10 minutes.
Can it be frozen?
Freeze the already baked and cold crumble well sealed with aluminum foil for up to 60 days. To consume, heat directly in the oven at 180°C for about 25 minutes until the fruit filling bubbles again.
What to serve with
Pairs perfectly with creamy vanilla ice cream, freshly whipped cream, black coffee, or chamomile tea.
Frequently asked questions
How to easily peel fresh peaches without wasting the pulp?
Score a cross on the bottom of the peaches, plunge into boiling water for 40 seconds, and transfer to an ice bath; the skin will come off whole just by pulling with your hands.
Why did the oat topping get soggy instead of crunchy?
This happens when the butter is mixed melted or warm; use strictly cold butter cut into cubes and bake at a high temperature of 190°C until well golden.
Can I use frozen fruit in this crumble recipe?
Yes, use the frozen peaches and blackberries without thawing beforehand, increasing the flour in the filling by 1 teaspoon to compensate for the extra liquid purged in the oven.
Does the fruit filling leak a lot of liquid when cutting?
When coming out boiling from the oven the filling is fluid; wait for the 15-minute rest off the heat so the wheat flour starch gelatinizes and retains the syrup.
