Rhubarb Crumble Tarts: The perfect way to round off a Sunday lunch
By leading celebrity chef Tom Kitchin.
A good crumble is the perfect way to round off a Sunday lunch and surely one of Britain’s most popular puddings. I do variations of crumble throughout the year, such as apple, greengage, rhubarb and red berry, according to the season, and I’m particularly fond of this rolled oatmeal topping, which works with any fruit.
250g plain flour, plus extra for dusting
50g icing sugar
150g unsalted butter, in pieces
1 free-range medium egg
1 free-range medium egg yolk, lightly beaten
6 rhubarb stalks, de-strung if necessary and cut into 1cm lengths
180g sugar, or to taste finely grated zest and juice of 1 orange
250g plain flour
pinch of sea salt
200g cold unsalted butter, in pieces
200g soft light brown sugar
75g rolled oats (or oatmeal)
few drops of pink food colouring
lemon thyme or shredded mint to finish (optional)
To make the pastry, sift the flour and icing sugar together into a food processor. Add the butter and pulse until the mixture resembles breadcrumbs. Add the whole egg and pulse briefly until the dough just comes together. Turn out onto a lightly floured surface, knead gently, then flatten into a round. Wrap in cling film and chill for 30 minutes.
In the meantime, for the filling, put the rhubarb into a heavy based saucepan with the sugar and orange zest and juice. Bring to a simmer, lower the heat and cook gently for 10–15 minutes until the rhubarb is softened but still holding its shape.
Meanwhile, to make the crumble, sift the flour and salt into a bowl. Add the butter and rub in with your fingertips until the mixture resembles coarse crumbs. Stir in the brown sugar, oats and a little food colouring – to give the crumble a nice pastel pink colour. Cover and chill for 20 minutes.
Roll out the pastry on a lightly floured surface to a 3–4mm thickness and use to line 4 individual flan tins, 7.5cm in diameter and 2.5cm deep. Trim the excess pastry away from the edges. Place in the fridge to rest for 15 minutes before baking. Heat the oven to 180°C/Gas 4.
Line the pastry cases with baking parchment and add a layer of baking beans. Bake the pastry cases ‘blind’ for 10 minutes, then remove the paper and beans and bake for a further 10 minutes until the pastry is cooked through. Remove the paper and beans and brush the inside of the hot pastry cases with the beaten egg
yolk to seal. Set aside on a wire rack.
Scatter the crumble on a baking tray and bake for 6–8 minutes until golden and crispy.
To serve, warm the rhubarb compote, if necessary, and use to fill the tart cases. Scatter the crumble evenly over the surface. Finish with a sprinkling of herbs or leave plain if you prefer. Serve with a scoop of vanilla ice cream or pouring cream.
