Grease a round 20 - 22 cm ( 8 - 9 inch) cake pan with a removable rim, and place a piece of baking paper on the bottom. Pour in the dough, smooth it out and place in the preheated oven at 200 ° C in the middle rack of your oven and bake for about 20 minutes until light brown.
FOR THE FILLING
In a medium pot add the red currants, sugar, lemon juice, water and cornstarch. Bring to a boil on medium low heat, stir constantly, cooking until thickened, about 8-10 minutes. Move to a clean bowl and let cool completely. Refrigerate for about 20 -60 minutes to chill and thicken it.
Place the stiff meringue on top of the red currant filling. Using the back of a spoon form peaks over the top of the cake. Bake for approximately 10-15 minutes or until golden. Turn the red currant cake halfway through baking so it browns evenly. Let cool completely before serving. Enjoy!
