Make the tart crust Recipe ID: 344146 or any crust of your choice. Make the filling while the tart dough is resting.
Put the egg and sugar in a bowl, and mix well with a whisk until it becomes pale in color. Sift the flour and corn starch into the bowl, and mix while adding the soy milk in little by little.
Loosely cover with cling film and microwave for 4 minutes at 600 W. Stir once every minute. Remove the cling film and microwave for another minute. If microwaving at 1000 W, reduce the total cooking time from 5 minutes to 4.
Pour the Step 2 mixture into the tart crust and bake for 15 minutes at 200°C, or 10 minutes at 240°C. Cook until the surface browns slightly, but if it looks like it will burn, cover with aluminium foil.
By coating the bottom of the crust with caramel, you can transform this into a pudding tart. For an easy caramel sauce recipe, check out Recipe ID: 620607.
Story Behind this Recipe
I modified a custard tart recipe I found in a magazine, and also replaced the milk with soy milk. This is surprisingly simple to make.
When heating the custard in the microwave, keep an eye on it and be sure to mix well. If it isn't sweet enough, add some sugar. It's also tasty if you brush the bottom of the tart crust with jam. If halving the recipe, microwave for 3 minutes.
