For the pastry
200g gluten free plain flour, plus extra for rolling
1 tsp fine sea salt
1½ tsp gluten free baking powder
125g unsalted lactose free butter, softened to room temperature, plus extra for greasing
125g caster sugar
1 large sprig thyme, leaves stripped
3 egg yolk
dry, uncooked rice, for baking
For the filling
250g ripe, even-size strawberry, hulled
4 tbsp icing sugar, sifted
2 tbsp balsamic vinegar
284ml tub lactose free double cream
finely grated zest 1 lemon
finely grated zest 1 lime
2 ripe (wrinkled) passion fruit, halved
6 large basil leaves, chopped
icing sugar and a handful small basil leaves to serve
Serves - 8
To make the pastry, sift the gluten free flour, salt and baking powder into a large bowl. Rub in the lactose free butter until it is the texture of crumbs, then mix in the sugar and thyme leaves.
Make a well in the centre. Beat the egg yolks together, then stir into the mixture with a table knife until it forms soft clumps.
Using your fingers, draw the pastry together into a rough dough. Turn out onto a lightly floured work surface and knead into a smooth ball. Cover with cling film and chill for at least 30 mins. Rub a little softened lactose free butter around a plain 20cm x 2cm flan ring.
Cover a heavy baking sheet with nonstick baking parchment and place the ring in the centre. Dust the work surface and rolling pin with flour. Lightly re-knead the dough until smooth, then roll out to a round roughly 30cm in diameter.
Lift the dough over the rolling pin and drape over the ring. Press gently into the sides and let the overhang fall on the outside. Break off a chunk of gluten free pastry and roll into a ball.
Dip into a little of the icing sugar, then use it to press the dough into the ring. Do not trim at this stage. Chill the tart case for at least 30 mins, preferably in the freezer.
Heat oven to 180C/fan 160C/gas 4. Cover the tart case with a large round of baking parchment, then half-fill with uncooked rice. Place in the centre of the oven and bake for 15 mins.
Remove and lift out the parchment and rice. Turn oven to 160C/fan 140C/gas 3, wait about 5 mins, then return the case and bake for a further 10 mins until golden brown.
Remove and cool for 10 mins. Using a small, sharp knife, cut away excess pastry, trimming the ring top. Loosen the sides with a knife, pull off the ring and leave to cool. The case should be biscuit crisp.
To make the filling, place the strawberries on a plate, dredge with the icing sugar and vinegar, then set aside. Beat the lactose free cream with the grated zests until just forming soft peaks.
Scoop the passion fruit pulp into a small sieve and rub through onto the cream with the back of a spoon. Stack the large basil leaves together, shape into a roll, thinly slice into shreds, then chop. Fold these into the lactose free cream.
When the base has completely cooled (it doesn’t matter if it has broken around the sides a little), assemble the tart. Spoon the lactose free cream into a piping bag without a nozzle, then pipe in small, even dollops over the base.
Drain the strawberries and press lightly onto the lactose free cream. Dust over more icing sugar, tuck in the small basil leaves among the strawberries and serve immediately.
