Leavened Cake

My grandparents invited me for lunch today.
As always it was far too delicious and far too much.
My grandmother Margot made her famous leavened cake as well.
While enjoying the cake she told me a little bit about the receipt and how she watched her mother making the dough when she was a child.
She also pointed out that many people don't properly can make leavened cake.
Do you have any experiences?

So here is the recipe you were asking for:

Leavened Dough Base Recipe

Ingredients:
500g flour
100g sugar
250ml milk
30g leaven
80g butter or margarine
1 pinch of salt

Heap all flour in a bowl. Make a deepening in the middle. Mix 50g of the sugar with the lukewarm milk; mix in the crumbled leaven and fill the mixed fluid into the deepening. Work in about one third of the flour so that a small, semi fluid dough develops. Scatter some flour over it and cover the dough with a blanket. Put it in a warm (and not windy) place for at least 20 minutes (can also be 30 to 60 minutes). After this knead in all other ingredients and cover it again; put it on a warm place for another 60 minutes to ?let it go?.
Now roll out the dough on a flour covered base; then put it onto the oiled baking-plate.
Put on your filling (e.g. apples ? see below) ? let it go for another 20 minutes and put it into the oven.

This amount is enough for a whole baking-plate.

Apple Cake (like that one on the picture)

Ingredients
The above mentioned leavened dough
2kg apples
100g sultanas or currants
sugar appropriate to the taste of the apples
1 small package vanilla sugar
1 shot of rum or brandy
some almond plates
half a teaspoon cinnamon

Put the dough onto the oiled baking-plate; thereby press it onto the plate border. Cover the dough with cut apples (1/8 of an apple per piece) in a flake like fashion. Then distribute the sultanas and the almond plates. Put the cake into the oven for 40 minutes with ?middle heat?. Afterwards drip the cake with melted butter. Put it back into the still hot oven for 5 minutes. Finally sprinkle fine sugar above it.

Hhm ... yummy.
