Blueberry & cream cheese crostata

 November 28-29, 2020

   

For the first time in more than a year, our Ottolenghi cooking club met in person and shared food together. In a common pattern for our club, I volunteered for dessert duty early and with enthusiasm. The most appetising, picnic-friendly recipe I could find was this blueberry and cream cheese crostata, which was published online to coincide with Fourth of July festivities.

It starts with a shortcrust pastry that's very heavy on the butter - I found that it absorbed the full quantity of flour without including any of the water in the recipe. I'm a devotee of food-processed shortcrusts but I washed my hands thoroughly and dug in as directed here - it worked out fine, though I'm not confident it was worth the extra messiness. The dough was sticky and challenging to handle on a hot day, and I'm glad it was always intended to look a little rough around the edges.

The shortcrust pastry is topped with a cheesecakey layer, tangy with lots of lime juice and zest, and then macerated and slightly mashed blueberries. I was supposed to hold over a little zest and icing sugar for a last-minute garnish but that was more fuss than I could stretch to, and I don't think any of us missed it.

This crostata was a big success with the club - the pastry was crumbly and toasty, and the cream cheese and blueberry layers played back and forth with richness and freshness, sourness and sweetness. I would definitely make this again, especially for a picnic setting, and I can't help wondering how a vegan adaptation might go.

Blueberry & cream cheese crostata

(slightly adapted from a recipe by Yotam Ottolenghi in The Guardian)

pastry

100g plain flour

50g wholemeal flour

30g icing sugar

1/4 teaspoon salt

145g butter, cold

65mL water, ice-cold (I didn't use this)

extra flour, for working the dough

milk, for brushing

cream cheese filling

200g cream cheese, at room temperature

50g icing sugar

2 teaspoons cornflour

3-4 limes, to make 1 tablespoon zest and 1 tablespoon juice

1/2 teaspoon vanilla

blueberry topping

200g blueberries

20g icing sugar

Prepare the pastry dough in a large bowl. Sift together the flours, sugar and salt. Chop the butter into 1.5cm cubes and squish it into the flour. Ottolenghi recommends leaving butter chunks intact, then using the water to bring the dough together. I ended up rubbing the butter through until all of the flour was incorporated, not including any water at all.

Scatter the flour over a work surface and a rolling pin. Roll the dough out into a 30cm x 20cm rectangle, fold the shorter sides into the centre and roll gently over them. Repeat folding in sides and rolling over the pastry twice more. Wrap the pastry in plastic and refrigerate the dough for at least 30 minutes (I left mine overnight).

Beat together the cream cheese filling in a medium bowl: start with the cream cheese, sift over the icing sugar and cornflour, and add the lime zest, juice and the vanilla. Beat thoroughly, until smooth.

In a small-medium bowl, sift the icing sugar over the blueberries and stir them together. Partially crush the blueberries with a fork, leaving some whole.

Lightly flour a long sheet of baking paper; unwrap the pastry and place it on the paper. Roll the dough out - Ottolenghi aims for a 32 cm-diameter circle, and I went for an oval that I could fit onto my baking tray. Transfer the paper and pastry onto a baking sheet. Spoon the cream cheese filling into the centre of the pastry, spreading it out but leaving a 1-2 cm border of pastry free around the edges. Dot the blueberry mixture across the cream cheese.

Use a knife to make 2 cm deep cuts in the pastry border at 8 cm intervals. Gently fold each pastry section over and inwards, so that they slightly overlap and form a thick edge. Refrigerate the crostata on its tray for 30 minutes.

Preheat an oven to 230°C. Brush the edges of the pastry with milk, and bake the crosata for 10 minutes. Turn the oven down to 180°C and bake for a further 25 minutes, until the pastry is golden and cooked through. After letting it rest on the tray for 5 minutes, transfer it to a biscuit rack to keep the pastry as crisp as possible. Allow it to cool for another 30 minutes or more before serving.
