Gerbeaud Walnut slice { Zserbó }

Yay, Another Hungarian classic cross-off my "to-bake" list! Like many things, something that seemed daunting was actually manageable and I would go as far as saying easy! Of course, I'm not saying I did a perfect job. I was a bit dry and crumbly. To suit my taste and my family's, this recipe still needs tweaking, but it is a very good base to work on.

Ingredients
250g Flour
100g butter, room temperature
50g sugar + 1 sachet vanilla sugar
1 egg yolk
50ml Milk
10g fresh yeast (**I had no fresh; so, sub. with instant. Will lessen the quantity on next bake)
salt, a pinch

Filling
150g Ground walnuts
100g sugar (reduced to 70g)
1 sachet vanilla sugar
 200g apricot jam
+++ Lemon zest
Note :- I'll add some milk next time to the dry filling**

Chocolate icing
100g chocolate (used 1x60g bar)
1 Tbsp vegetable oil (not olive oil!)
+++ Rum

Ground walnuts to garnish

Method :-

1) Get ready the filling by mixing together ground walnuts, sugar, vanilla sugar and lemon zest +**.Set aside.
2) Start dough by bring milk to luke warm, add in instant yeast and a little sugar. Let it sit for 10 mins. until yeast mixture starts to foam/come alive.
3) Once yeast mixture is reading. In mixing bowl, mix together flour, sugar, salt. Then work in the butter until it resembles bread crumbs. Then add in the egg yolk and yeast mixture. Combine well and start to knead until smooth. Let it rest in a covered bowl for an hour.
4) 30 mins. into the dough resting time, start pre-heating the oven at 180°c.
5) Once dough full rest, divide it into 4. Start rolling out the 1 dough ball, enough to cover a 18cm round cake tin. Lay the rolled out dough into the the cake tin. Spread the apricot jam evenly and then sprinkle the walnut filling (1). Repeat this process for 3 layers and cover it with final rolled out dough. Pierce the layers with a knife all the way through to let any steam out when baking.
6) Bake for 30-35 mins. until golden brown.
7) Once the cake is cooled, start making the chocolate icing by melting chocolate by using double boiler or microwave (max 1min) and add in vegetable oil to loosen. Spread all over the cake and let it set in room temperature.


Note:-
It is best to let the cake sit over night to let the flavour melts together.
