The sweet and crumbly biscuit crust acts as a contrast to the sourness of both yogurt and passion fruit in these easily-put-together tarts. For something sweeter, stir a couple of tbsp of icing sugar into the yogurt. The crispness is essential, but use a loose-textured, buttery biscuit rather than a hard gingernut. Makes 6
For the crust:
crumbly ginger biscuits 180g
cardamom pods 10
butter 80g
For the filling:
passion fruits 6
thick (strained) yogurt 500g
To finish:
crystallised rose petals 1 tbsp
passion fruits 2
You will also need 6 x 10cm metal rings or loose-bottomed tart cases.
Turn the biscuits to fine crumbs in a food processor or by putting them in a plastic bag and crushing with a rolling pin. Crack the cardamom pods, extract the seeds and grind them to a fine powder using a pestle and mortar or spice mill. Melt the butter in a small pan, add the cardamom then the crumbs and stir thoroughly. Set 4 tbsp of the crumbs aside.
Place the tart cases or metal rings on a baking sheet and divide the crumb mixture between them, packing them down lightly with the back of a spoon to form a thin disc. Refrigerate for 15 minutes until the butter has set.
