There’s a small dessert counter tucked behind a tea shop on a side street I almost never walk down, and I would not have found it if a guide had not handed me a numbered ticket and told me to keep moving. It was the last stop on an eight-stop neighborhood tour. Eighth out of eight.
By that point I was full, faintly tired, and already half-thinking about my couch. Then a little glass tumbler appeared, with a ribbon of pink running through cold cream and a green-flecked drift of crumble across the top. Eight years later, here we are.
The Eighth Stop That Changed the Whole Tour
We had eaten our way through tacos, dumplings, a grain bowl, two pastries, a bao, and a brothy soup. The guide kept saying “save room for the last one,” and I kept not saving room, because nobody ever does. Then she pulled us into a narrow tiled room with two stools and a chalkboard that just said “fool of the day.”
The owner’s name is Margot, and she trained in London before opening her tiny place on this block. She told us, very matter-of-factly, that a fool is one of the oldest English desserts. The word shows up in John Florio’s Italian-English dictionary in 1598, and the earliest printed recipe is in The Compleat Cook in 1655, a book of recipes from Queen Henrietta Maria’s court. She said all of this in the tone someone might use to recommend a sandwich.
The version she made that afternoon was roasted Yorkshire rhubarb, soft cream, and a pistachio crumble. I went back the next week. I went back the week after that. I have spent the years since trying to crack it at home.
Why This Roasted Rhubarb Fool with Pistachio Crumble Lives in My Head
For one thing, it is pink. Forced rhubarb, the kind grown in the dark sheds of the Rhubarb Triangle in Yorkshire between Wakefield, Morley, and Rothwell, has a color that does not really exist anywhere else in food. Not strawberry red. Not raspberry. A quiet, blushing, candle-lit pink.
For another, it is restrained. A fool is not a trifle. There is no sponge, no booze-soaked base, no custard layer (although historically, before forks were common, fools were actually made with eggy custard, not whipped cream). It is fruit folded through cream and that is all. The simplicity is the point. Margot was very firm about this when I asked her once if she ever added cake. She did not add cake.
The pistachio crumble is the part that is not strictly traditional. It’s a modern British move, the kind of thing you see in magazines and restaurants now, a little bridge between an old English pudding and the slightly Middle Eastern feeling of cardamom and green nuts. I love it for the crunch against the cream. I also love it because it makes the dessert feel a little dressed up.
What I Used
- Forced Yorkshire rhubarb when I can find it, in 2 inch batons
- Superfine sugar, to coax the syrup out of the stalks
- Orange zest and a splash of fresh orange juice
- Vanilla bean paste, or scraped seeds from a pod
- Very cold heavy cream (the closest thing we get to UK double cream)
- A little powdered sugar for the cream
- All-purpose flour, rolled oats, demerara sugar
- A pinch of ground cardamom and fine sea salt
- Cold unsalted butter, diced
- Roughly chopped shelled pistachios, the brightest green ones I can find
Inside the Pan with the Rhubarb
Once the rhubarb hits the hot tray with the sugar and the orange juice, something quiet starts happening under the parchment. The sugar pulls water out of the stalks, the way salt would draw moisture from a cucumber, and that water meets the heat and dissolves the sugar into a thin, translucent syrup. The red skin, pressed against the liquid, releases its color in slow ribbons, staining the syrup pink before the fruit itself even looks done.
Inside each baton, the cell walls are softening. Pectin loosens. The acidity, the very thing that made these stalks so eye-watering raw, mellows down to something almost wine-like. The orange zest oils bloom in the heat, throwing off a smell that lands somewhere between marmalade and candle smoke. Vanilla seeds darken into the syrup like little flecks of ink.
You want to pull it before the batons collapse. Tender, but still holding their shape. The minute you stir, you have stewed rhubarb. Without a stir, you have something prettier.
The crumble does its own quiet work on its own tray. The butter melts into the flour and oats, the demerara softens and re-crystallizes around the pistachios, and the whole tangle goes from wet sand to crisp golden rubble. It firms up as it cools, the way a cookie does.
Folding It All Together
Cold cream is very good at trapping air. When you whisk it cold, the fat globules link and net around tiny bubbles, and you get those soft floppy peaks that look like they might still topple. Stop there. Over-whipped cream is a heavy, grainy thing, and a fool made with stiff cream is no longer a fool.
I crush about two thirds of the cooled rhubarb with a fork, leaving the rest in soft, intact pieces. Two tablespoons of the reserved syrup go over the cream first. Then the crushed fruit. Then I fold, two or three turns of the spoon, no more.
You are looking for marbling. Streaks of pink syrup running through the cream like watercolor. If it goes uniformly pink, you have stirred too much. The marble is the whole point.
A Few Worth-It Twists
For a richer version, swap a quarter of the cream for thick vanilla custard or Greek yogurt. Custard is, historically, what fools were originally made with, before whipped cream took over in the late 17th century. Yogurt is just lovely.
If forced rhubarb is out of season, outdoor rhubarb in April through June works, though the color will skew more sunset than ballet slipper. The pinch of cardamom in the crumble plays beautifully with the pistachios. Sometimes I’ll whisk a teaspoon of orange blossom water into the cream if I’m feeling festive.
Margot’s tea shop is still there, last I checked, and I still go. But I make this at home now too, in coupes I bought specifically for it. Somehow it still tastes like that eighth stop on a tour I almost did not finish.
Roasted Rhubarb Fool with Pistachio Crumble
Ingredients
Equipment
Method
- Preheat the oven to 375 F. Line a rimmed baking sheet with parchment paper.
- Arrange the rhubarb batons in a single layer on the prepared sheet. Sprinkle evenly with the superfine sugar, orange zest, orange juice, and vanilla bean paste, then turn gently to coat.
- Roast for 15 to 18 minutes, just until the rhubarb is tender when pierced but still holds its shape. Do not stir during roasting. Let cool completely on the tray, then drain off and reserve the syrupy juices in a small bowl.
- While the rhubarb cools, make the crumble. In a bowl, combine the flour, oats, demerara sugar, cardamom, and salt. Add the cold diced butter and rub between your fingertips until the mixture looks like coarse crumbs with some pea sized lumps. Stir in the chopped pistachios.
- Scatter the crumble onto a small parchment lined sheet pan in clumps. Bake at 375 F for 14 to 16 minutes, stirring once halfway, until deep golden and crisp. Cool completely; it will firm up as it sits.
- In a chilled bowl, whip the cold heavy cream with the powdered sugar to soft, floppy peaks. Stop while the cream still flops over on itself; over-whipped cream will make a heavy fool.
- Lightly crush about two thirds of the cooled rhubarb with a fork, leaving the rest as whole pieces. Drizzle 2 tablespoons of the reserved syrup over the cream, then spoon in the crushed rhubarb.
- Using a large spoon, fold the rhubarb through the cream just two or three times so streaks of pink syrup ribbon through the cream. Do not over-mix; the marbled look is the point.
- Spoon the fool into 6 coupes or glasses, tucking the reserved whole rhubarb pieces between layers and finishing with a final drizzle of syrup on top.
- Chill for at least 20 minutes and up to 2 hours. Just before serving, shower each glass generously with the pistachio crumble so it stays crisp against the soft cream.
