Making shortcrust pastry has to be amongst the easiest and the best skills to have in the kitchen. For providing the perfect backdrop to an endless variation in fillings, from savoury, like the leek and dorset blue tart I made at River Cottage, to a sweet seasonal fruit tart, shortcrust pastry is perfect. The glorious days of blueberries are imminent, so let’s make a rustic tart, the one I baked for the folks at Heart Home, when they came out to visit the old cottage.
I like to make a large recipe, and bake two. Start with 500 grams of flour (I used a mix of white and whole spelt), 250 grams of cold unsalted butter, a couple of egg yolks, a pinch of salt, and 100 ml of cold milk, though we may not use it all. For the filling, cook five or six cups of blueberries until their liquid reduces a bit, then remove from heat and toss with 1/4 cup of sugar and 1/3 cup of light flour. Squeeze half a lemon in, too.
Cut the butter into the flour til it’s in tiny pieces, and then start rubbing the butter into the flour. (I like to wash my hands in cold water, as you don’t want to melt the butter in!) You’re looking for the moment when the flour turns yellow, and resembles breadcrumbs.
Yellow? Excellent. Mix in the two egg yolks.
Add some milk in splashes, just until the dough comes together and no more. Knead it for a minute. You could break the dough in half and form two balls. I wrap mine in parchment, then toss it in a bag to chill in the fridge for a half hour. Heat your oven to 375F/180C. On a very lightly floured surface, roll the dough out thinly, and lift it onto a flat, parchment lined tray.
Dollop the blueberry filling into the middle, fold the pastry in, and sprinkle with some coarse sugar if you’ve got some around. Bake it for close to an hour! And serve, cooled, with some whipped cream. It looks
incredibly gorgeous when it’s baked, especially if you’ve got a professional photographer and a pair of magazine editors to document the event.
