This article will take you through everything you need to know about making the perfect crumble, from selecting your ingredients to serving suggestions.

Key Ingredients for Rhubarb Crumble with Apple

Essential Ingredients for the Filling

To make the best rhubarb crumble with apple, you’ll need just a few simple ingredients that come together to create the perfect balance of sweet and tart. Start with about 500g (4 1/2 cups) of rhubarb—it should be fresh, with vibrant red stalks. Don’t forget to clean the rhubarb and remove the leaves, as they are toxic! Then, you’ll add three Granny Smith apples (about 600g or 1.2lb whole), peeled and chopped into small cubes. These apples are perfect for crumbles, as their tartness complements the rhubarb’s tang while still holding their shape when cooked.

To round out the filling, mix in 1/3 cup of white sugar to sweeten the naturally sour fruits. Adding orange zest is optional, but it brings a wonderful citrusy zing to the dish that enhances the flavor of both the rhubarb and the apples. The best part? This filling is not only delicious but also simple to prepare—just toss everything together and you’re good to go!

Perfecting the Crumble Topping

The crumble topping is where you get that irresistible crunch, and it’s just as important as the fruit filling! For this topping, you’ll need 1 cup of rolled oats (not quick or steel-cut), which add texture and a subtle nuttiness. Combine it with 1 cup of plain flour and 3/4 cup of tightly packed brown sugar. The brown sugar helps create a caramely flavor, which contrasts beautifully with the tart fruit. You’ll also need 1/2 tsp of baking powder to give the topping a light lift and 1/2 tsp of cinnamon powder for that warm, comforting aroma.

The key to a perfect crumble is the butter—you’ll need 90g (6 tbsp) of unsalted butter, melted, to bind everything together. Finally, a pinch of salt will help bring out all the flavors and balance the sweetness of the topping. Mix all of these ingredients together until you get a sandy texture, and then you’re ready to top off your rhubarb crumble with apple!

Step-by-Step Guide to Making Rhubarb Crumble with Apple

Preparing the Rhubarb and Apple Filling

Start by preheating your oven to 200°C (375°F) (or 180°C fan). While the oven warms up, it’s time to get your fruit ready. Take your rhubarb and apples, and make sure they’re cleaned, peeled, and chopped. Once that’s done, toss them in a large bowl with the white sugar and orange zest. Give everything a good mix to ensure the fruits are evenly coated with sugar and zest. Then, transfer the fruit mixture into a 30 x 20cm (12 x 8″) baking dish. Spread it evenly, making sure the rhubarb and apple pieces are well distributed.

Making the Perfect Crumble Topping

Next, it’s time to prepare the crumble topping. In a separate bowl, combine the rolled oats, flour, brown sugar, baking powder, and cinnamon powder. Give everything a good stir to mix it up. Now, pour in the melted butter and stir again. The texture should resemble coarse sand, and the mixture should stick together when pressed. Grab handfuls of the crumble mixture and press them into clumps with your hands. This creates larger, chunky bits that will add crunch when baked. Scatter the crumble evenly over the fruit filling, covering it completely.

Baking and Serving

Now, pop the dish in the oven and bake for about 35 minutes, or until the crumble is golden brown and the fruit is bubbling around the edges. The rhubarb should be soft but not mushy, and the topping should have a nice, crisp texture. Once it’s out of the oven, let it rest for 5 minutes to cool slightly and allow the juices to thicken.

When it’s ready to serve, scoop generous portions of your rhubarb crumble with apple into bowls and top with a scoop of vanilla ice cream or a drizzle of custard for the perfect finishing touch. This dessert is a warm, comforting treat that’s sure to please everyone!

Tips for Perfecting Rhubarb Crumble with Apple

Adjusting for Different Apple Varieties

When making rhubarb crumble with apple, choosing the right apple variety is key. While we’ve recommended Granny Smith apples for their tartness and texture, you can experiment with other apples too! However, keep in mind that the flavor and texture of different apples vary. For example, Fuji apples are much sweeter than Granny Smith, so you might want to reduce the sugar slightly in the filling to avoid overpowering the tartness of the rhubarb.

If you opt for a sweeter variety of apple, such as Gala or Honeycrisp, you may also want to add a bit more lemon juice or citrus zest to balance out the sweetness. The goal is to maintain the perfect balance between the tangy rhubarb and the sweetness of the apples, so don’t be afraid to tweak the recipe to suit your taste.

How to Achieve the Right Crumble Texture

The crumble topping is where you can really play around with the texture. For a crunchier crumble, you can increase the amount of rolled oats in the mixture, or even add chopped nuts like almonds or pecans. These will add extra crunch and depth of flavor, making each bite even more satisfying.

On the other hand, if you prefer a softer, more delicate topping, simply reduce the amount of oats and butter slightly. The key is to ensure that the crumble doesn’t fall into the fruit filling and become too soggy. A quick tip: avoid overmixing the crumble ingredients. The mixture should be chunky, not too fine, to maintain that crispy texture on top of your rhubarb crumble with apple.

Rhubarb Crumble Variations

Combining Other Fruits with Rhubarb

While rhubarb crumble with apple is a classic, you can easily customize the recipe by adding other fruits to the mix. For instance, strawberries are a popular pairing with rhubarb, adding a bit of sweetness and an extra burst of color. Simply swap or mix the apples with an equal amount of fresh strawberries for a different take on your crumble.

You can also experiment with pears, which have a soft, sweet flavor that complements the tartness of rhubarb. Try using Bosc pears for a firmer texture that holds up nicely when baked. For an extra touch of flavor, consider mixing blackberries or raspberries with the rhubarb—they pair well with the sour tang of rhubarb and provide an additional fruity layer to the crumble.

Making a Gluten-Free or Vegan Rhubarb Crumble

If you’re looking for a gluten-free or vegan version of rhubarb crumble with apple, it’s relatively easy to make substitutions. For a gluten-free option, use almond flour or gluten-free oats in place of regular flour and oats. You can also swap butter with coconut oil or a vegan butter substitute to make it vegan-friendly. These substitutions won’t change the flavor drastically, but they will make the crumble suitable for those with dietary restrictions. The result is still a delicious, comforting dessert!

Serving and Pairing Ideas

What to Serve with Rhubarb Crumble with Apple

Rhubarb crumble with apple is delicious on its own, but pairing it with the right accompaniments can really elevate the experience. A scoop of vanilla ice cream is a classic choice, offering a cool, creamy contrast to the warm, tangy crumble. The smoothness of the ice cream melts beautifully into the fruit filling, making every bite extra indulgent.

Alternatively, you can serve your crumble with a generous dollop of whipped cream. If you’re after something richer, consider pouring over custard—its creamy, slightly sweet texture complements the tartness of the rhubarb perfectly. For a more decadent twist, try drizzling some caramel sauce over the top for an added layer of sweetness.

If you’re looking for a lighter option, a scoop of Greek yogurt can also work wonders. Its creamy texture and slight tang can balance out the sweetness of the crumble without overpowering it.

Perfect Pairings: Ice Cream, Custard, or Cream?

While ice cream, custard, or cream are all great choices, each brings its own charm to the table. For a traditional, comforting feel, vanilla ice cream is the go-to. It’s simple and complements the dessert without stealing the spotlight. If you’re in the mood for something rich and luxurious, go for custard—it adds a touch of indulgence. On the other hand, whipped cream is light and airy, making it an ideal pairing if you prefer a less heavy topping.

Ultimately, it’s all about personal preference, so feel free to experiment with different options until you find your perfect match!

Frequently Asked Questions (FAQs)

Can I Use Frozen Rhubarb for Rhubarb Crumble with Apple?

Yes, you can use frozen rhubarb if fresh rhubarb isn’t available. The good news is that frozen rhubarb holds its flavor well, so it’s a perfect substitute in rhubarb crumble with apple. However, keep in mind that frozen rhubarb may release more moisture during baking, which can make the filling a bit runnier. To combat this, consider adding a little extra cornstarch or flour to thicken the filling and ensure it holds its shape.

How Do I Know When the Rhubarb Crumble with Apple is Done?

The key to perfectly baked rhubarb crumble with apple is a golden-brown topping and bubbling fruit filling. When the crumble is deep golden and the fruit juices are bubbling around the edges, you’ll know it’s ready. Typically, baking for 35 to 40 minutes should do the trick. If you’re unsure, insert a knife into the filling—the rhubarb should be tender but not mushy.

Can I Make Rhubarb Crumble with Apple in Advance?

Absolutely! Rhubarb crumble with apple can be made in advance and stored in the fridge for a day or two before baking. Simply prepare the fruit filling and crumble topping, store them separately, and assemble the dish right before you bake it. If you’ve already baked it, you can refrigerate leftovers for a few days, and simply reheat it in the oven for that fresh-baked feel.
