If you like key lime pie, you’ll like this. It hits the same notes, but is even more fragrant and fruity, thanks to all the passion fruit, lime and the crunchy ginger biscuit base. Condensed milk is one of the best things that comes in a tin and I welcome any opportunity to use it. Incorporating it into the filling helps this tart bake much faster than a traditional custard, and brings a delightfully creamy, silky texture.
Passion fruit and ginger tart
Prep 20 min
Cook 25 min
Chill 2 hr
Serves 8
For the base
200g ginger nut biscuits
80g unsalted butter, melted
1 tbsp caster sugar
For the filling
4 large egg yolks
100ml passion fruit juice, strained from 10-12 passion fruit, seeds reserved
Zest and juice of 2 limes
¼ tsp salt
397g tin condensed milk
150ml double cream
Heat the oven to 190C (170C fan)/375F/gas 5, and line the base of a loose-bottomed 23cm cake tin with baking paper.
For the base, crush the biscuits in a food bag (or use a food processor) until they are mostly fine. Put the crumbs in a large bowl, add the melted butter and sugar, and stir well to coat. Press the biscuit mix into the base of the lined tin, then bake for 10-12 minutes, until the edges look lightly browned. Remove and leave to cool a little. Turn down the oven to 160C (140C fan)/325F/gas 3.
For the filling, put the egg yolks, passion fruit juice, lime juice and zest, and salt in a bowl and mix to combine. Stir in the condensed milk and mix again until smooth. Pour the filling on to the biscuit base, then bake for 13-16 minutes, until the custard is set with a very slight wobble in the middle. Leave to cool completely, then chill for one to two hours.
To make the topping, lightly whip the cream to soft peaks, then spoon dollops on to the tart. Top with some of the reserved passion fruit seeds, then slice and serve.
