Finding a full kilogram of vibrant, intensely tart rhubarb isn’t just a purchase for me; it’s a delightful culinary challenge, especially as a baker renowned for transforming humble plant-based ingredients into edible works of art. My goal with this particular harvest wasn’t just to make a crumble, but the Rhubarb & Ginger Crumble with a Hint of Orange. The inherent tartness of the rhubarb itself demanded a bold and complementary counterpoint. I envisioned the zesty, warming kiss of fresh ginger, a natural partner to cut through the fruit’s acidity and add comforting depth. But it was the bright, almost ethereal whisper of orange zest that truly elevated this dish, infusing a sun-drenched sweetness and subtle perfume that makes every bite sing. This recipe wasn’t merely conceived; it was destined to become a harmonious, comforting masterpiece, carefully balanced to showcase the rhubarb’s best qualities and make the absolute most of a generous harvest. And, as your own golden creation bakes to perfection in the oven, consider settling in with the wonderfully therapeutic story of Barbara – a tale of chopping, healing, and sweet solace – which you’ll find just a little further down the page, offering captivating entertainment while you wait.

My Famous Rhubarb & Ginger Crumble with a Hint of Orange
Equipment
- Large baking dish (approx. 25×30 cm or a large round pie dish)
- Large mixing bowls
Ingredients
For the Rhubarb Filling:
- 1 kg rhubarb washed, trimmed, and cut into 2-3 cm pieces (no need to peel unless very tough)
- 200 g caster sugar granulated sugar works too – *adjust to your rhubarb’s tartness and your preference!*
- 2 tablespoons fresh ginger finely grated or minced
- Zest of 1 large orange
- 2 tablespoons cornstarch or arrowroot powder
- 1 teaspoon vanilla extract
For the Vegan Crumble Topping:
- 200 g plain all-purpose flour
- 100 g rolled oats not instant
- 150 g light brown sugar for that lovely caramel note
- 1/2 teaspoon ground cinnamon optional, but highly recommended!
- Pinch of sea salt
- 150 g cold vegan butter the block-style is best here, like Miyoko’s, Earth Balance stick, or Flora plant butter, cut into cubes
Instructions
- Preheat & Prepare: Preheat your oven to 180°C (350°F) fan/convection, or 200°C (400°F) standard. Lightly grease your baking dish.
Make the Rhubarb Filling:
- In a large bowl, combine the chopped rhubarb, caster sugar, grated ginger, orange zest, cornstarch, and vanilla extract.
- Toss gently to ensure the rhubarb is evenly coated. The sugar will start to draw out some of the liquid. The cornstarch is crucial here – it will thicken the juices into a lovely, glossy sauce, preventing a watery bottom.
- Pour the rhubarb mixture into your prepared baking dish, spreading it evenly.
Prepare the Vegan Crumble Topping:
- In a separate large bowl, whisk together the flour, rolled oats, light brown sugar, cinnamon (if using), and pinch of sea salt.
- Add the cold, cubed vegan butter. Now, this is where the magic happens! Using your fingertips, rub the butter into the dry ingredients. You want to work quickly to keep the butter cold.
- Continue rubbing until the mixture resembles coarse breadcrumbs, with some larger pea-sized clumps of butter remaining. *Don't overmix!* Lumps are your friends here; they create that irresistible crunchy texture. You can also do this in a food processor with pulse function, but I find the hand method therapeutic and often more effective for that perfect crumb.
Assemble & Bake:
- Sprinkle the crumble topping evenly over the rhubarb filling, ensuring the entire surface is covered.
- Place the baking dish on a baking tray (to catch any delicious, bubbly overflow) and bake for 40-50 minutes.
- You'll know it's ready when the topping is a deep golden brown and the rhubarb filling is bubbling merrily around the edges, soft, and translucent.
Rest & Serve:
- Remove from the oven and let it cool for at least 15-20 minutes before serving. This allows the juices to thicken further and prevents the crumble from collapsing into a sloppy (albeit still delicious) mess.
- Serve warm, with a generous dollop of my homemade vegan vanilla custard, a scoop of creamy coconut ice cream, or even a swirl of whipped aquafaba cream.
Notes
Chef’s Notes
- Sweetness is Subjective: Rhubarb varies wildly in tartness throughout the season and depending on the variety. Taste a tiny piece of your raw rhubarb! If it’s very tart, you might want to add another tablespoon or two of sugar to the filling. You can always reduce it too.
- Don’t Skimp on the Ginger: The fresh ginger is key to balancing the rhubarb. Don’t use dried ginger powder here; it won’t give you the same vibrant punch.
- Texture is Key: For the crumble topping, resist the urge to overwork it. A light hand will ensure a tender, crumbly topping.
- Storage: Leftovers (if there are any!) can be stored covered in the fridge for up to 3-4 days. It reheats beautifully in the oven or microwave.
Allergens:
- Gluten (from Wheat flour and Oats)
- Soy (commonly found in vegan butter; check your specific brand’s ingredients)
- Nuts (specifically Coconut, if your chosen vegan butter contains it; while botanically a fruit, it’s often grouped with tree nuts for allergen labeling in some regions like the US)
Emission Hotspots:
- Shop to home transportation, if a combustion car is used
Sustainability tips:
- Walk or bike to the supermarket
- Embrace the Whole Stalk: For rhubarb, there’s no need to peel the stalks – the skin adds colour, texture, and nutrients. Simply trim the very ends and discard the leaves (which are toxic).
- Freeze Excess Rhubarb: If you find yourself with more rhubarb than you can use in one go, chop it and transfer to a freezer-safe bag. It’ll keep for months and can be used directly from frozen in future crumbles or compotes.
- Smart Leftovers: This crumble reheats beautifully! Store any leftovers in an airtight container in the fridge for up to 3-4 days. Reheat gently in the oven or microwave, and enjoy as a breakfast treat with some vegan yogurt, or as an afternoon pick-me-up.
- Compost Scraps: Any rhubarb trimmings, orange peels, or other fruit/veg scraps can be added to your compost bin, returning nutrients to the earth.
- Source Locally & Seasonally: Rhubarb is a fantastic seasonal ingredient in many temperate climates. Buying it from local farms or markets (especially during its peak spring/early summer season) drastically reduces transportation emissions. The same goes for ginger and oranges – look for locally grown options where possible.
- Choose Sustainable Vegan Butter: While vegan butter is inherently lower carbon than dairy butter, look for brands committed to sustainable palm oil (RSPO certified) or even better, palm-oil-free alternatives.
⚠️ Important Attention note for guinea pig owners! ⚠️
Please be aware that rhubarb leaves are toxic and should NEVER be fed to guinea pigs (or any other pets) due to their high concentration of oxalic acid. While the stalks are edible for humans, they are also high in oxalic acid, which can be harmful to guinea pigs, causing kidney problems and digestive upset. It’s best to avoid feeding any part of the rhubarb plant to your furry friends. Stick to guinea pig-safe veggies!

Featured Story
When Life Gives You Rhubarb

Barbara’s kitchen had, in recent weeks, become less a place of culinary delight and more a high-stakes arena for emotional processing. The divorce papers, finally signed, had left a peculiar emptiness, a sort of silent echo where arguments used to be. It was into this void that the rhubarb arrived: a gargantuan, intimidating bundle from the local market, weighing in at what felt like a metric tonne. It wasn’t planned; it just appeared, a flash of indignant pink amongst the greens, as if daring her to do something about it. And Barbara, with a new, simmering rage she hadn’t known she possessed, decided she would.
The first stalk was a revelation. Each crisp, defiant thwack of the knife against the cutting board was less about preparing fruit and more about exorcising demons. “That’s for the car insurance you ‘forgot’ to pay,” she’d mutter, slicing with precision. “And that,” a particularly aggressive hack, “is for the two years you spent perfecting that ridiculous sourdough starter while I fixed your socks.” The rhythm became hypnotic, a furious, cleansing ballet of blade and fibrous pink, each neat segment a tiny victory. The air, usually thick with the scent of simmering resentment, began to fill with the bright, slightly sweet aroma of pure, unadulterated rhubarb potential. This wasn’t just baking; this was active, culinary vengeance, subtly disguised as comfort food.
What emerged from the oven was nothing short of miraculous: mountains of bubbling, fragrant crumble, its golden top crust perfectly crisp, its interior a symphony of tartness and warmth. Tray after tray, she baked, the sheer volume of rhubarb a testament to her newfound, furious productivity. The kitchen, once sterile with unspoken grievances, now hummed with a delicious, golden glow. Only then, with the last crumbly morsel cooling on the counter, did Barbara survey her handiwork. Twelve generous portions. Enough to feed a small army. Or, more accurately, enough to feed a family that no longer existed. The silence returned, this time filled not with echoes of arguments, but with the cloying sweetness of triumph… and an awful, solitary understanding that she had nobody left to share it with.
Culinary Reality Check

Oh, this crumble. It’s a confection born of necessity, perhaps, but perfected by a certain… intensity. A glorious, bubbling testament to the power of a good bake, designed to comfort and delight, even if it occasionally challenges the very fabric of self-restraint. Here’s the unfiltered truth, straight from my notoriously honest kitchen:

Taste
Prepare for a complete surrender. This isn’t just delicious; it’s the sort of flavour that makes one question the very concept of “enough.” You’ll want more, then more still, then consider drastic measures to acquire the final spoonful.

Portion Size
The recipe claims it serves 8. This is a cruel fiction, a polite suggestion for a world with far more self-control than mine. In reality, consider it a decadent feast for two very determined individuals, or perhaps four who are willing to engage in a quiet, yet fierce, battle for the last crumb.

Combination
A true masterclass in culinary alchemy. The unapologetic tang of the rhubarb performs a perfect, desperate dance with the fiery kiss of fresh ginger. And the orange? That’s the unexpected whisper, the note that elevates it from mere dessert to a symphony of comfort. Yes, the sugar content seems… generous, but it’s less an addition and more a necessary counter-measure, taming the rhubarb’s formidable acidity into a sweet, yielding submission. Adjust with caution, perhaps a quarter less if your rhubarb is mild, but know that audacity has its rewards here.

Texture
A marvel. The topping achieves that elusive state of perfection: simultaneously crumbly and crisp, with pockets of delightful chew from the oats, all melting into the tender, almost jammy surrender of the fruit below.

Spices
The ginger isn’t merely present; it announces itself with a warm embrace, a necessary partner to the rhubarb’s tartness. The orange zest is the elegant counterpoint, a bright, sunny note that lifts the entire composition.

Timing
Remarkably accurate, a rare solace in a world of uncertainties. Though, one must factor in the intensity of the chopping; the rhythmic thwack of knife on stalk can be surprisingly therapeutic, and one might find oneself extending the process for purely emotional benefit.

Processing
Even on the most chaotic of days, when despair looms and the universe seems to conspire against you, these instructions remain foolproof. They guide you from raw ingredients to golden perfection with a benevolent, almost uncanny precision.

Completeness
The recipe, in its glorious entirety, provides everything you need. No vital ingredient is overlooked, no crucial step omitted. Even a soul adrift will find their way to a perfectly baked crumble.

Environment
If we were to subsist purely on this plant-based marvel, the planet would, I daresay, offer a collective sigh of relief. It’s a whisper of planetary redemption, a dessert that aligns with greener skies, if not thinner waistlines.

Health
Here, we must inject a dose of tragicomic reality. While this crumble is a beacon of plant-based goodness, brimming with wholesome rhubarb and oats, it is, in its present form, rather enthusiastic about sugar. It truly is vegan, and that’s a stellar achievement for the planet, but its quantities of sweetness and refined flour mean it’s less a daily staple from the EAT-Lancet playbook and more a joyous, occasional rebellion.

Tips for Redemption
My advice? Embrace the recipe exactly as it is. It’s a masterpiece of balance and flavour, requiring no meddling. Your greatest challenge, my dear, will be resisting the urge for a second, then a third, slice. Remember, joy in moderation: too much sugar is rarely a friend, and rhubarb, in copious, relentless quantities, carries its own quiet warning about oxalic acid. Enjoy its brilliance, but perhaps not for every meal, lest your kidneys stage a polite, yet firm, intervention.
