To make the tart
shells, sieve together flour and salt into a deep bowl. Add the chilled butter and rub it into the flour with your fingertips till it resembles breadcrumbs.
Add sufficient ice cold
water and knead lightly into a dough. Cover the bowl with cling film and keep it in the refrigerator for 30 minutes.
Take the dough out of
the refrigerator, keep it on the worktop and roll out into 3 mm thick sheet.
Cut into roundels with
a fluted cookie cutter and line the tart moulds with them. Prick with a toothpick so that the dough does not puff while baking.
Keep them on a
baking tray, keep the tray in the preheated oven for 7-10 minutes.
Take the tray out of
the oven and set aside to cool.
To make the custard
sauce, mix custard powder and a little milk in a little bowl.
Heat the remaining
milk with castor sugar in a non-stick pan and when it begins to boil, add the custard powder mixture and mix well and cook, stirring continuously till the mixture thickens.
Halve all the gapes
and strawberries. Chop the kiwi.
Fill the tarts with some
custard sauce and then garnish it with mixed fruits and serve immediately.
