apple štrůdl beer dough

yes, beer!!!
...i make apple štrůdl (pronouced stroodle - it's like apple pie but in a roll) almost every week and a friend recommended beer dough to me. at first i was a little hesitant - beer, only 3 ingredients and no egg? but i decided to try it and it was the best dough i have ever tried and i'm sticking with this recipe for good!!! so here it is...only i have 4 ingredients, cause i like mine a little sweet(eventhough the beer makes it sweet a little already i still add a tbs of sugar).

400g flour - i use medium(as opposed to finely) ground
125g softened unsalted butter
200ml beer

1 tbsp sugar(optional)

directions:
mix untill smooth and let sit in the fridge - makes it easier to roll out!

note: i'm sure the taste differs a little depending on the beer - i used Svijany - a czech tradtional type of beer. and i would say it's a bit sweeter than american beer.

apple filling:

6-8 apples of choice (my fave is james grieve!)

2-3 tbsp sugar

cinnamon 2tsp
handfull of chopped walnuts (optional)

crumb topping - piškoty or graham crackers

directions for rolling:
- make a strip of apple filling in 1/3 of the dough, leaving
approx. 4cm of the ends blank(they will be tucked in)
- sprinkle a thin layer of crumbs(i just crush the piškoty
with my fingers) on top - to soak up some of the juice
from the apples, so the roll isn'y too soggy)
- fold over the 1/3 flap of dough
- roll over
- add a thin strip of apple filling + crumbs
- fold ends inward
- fold the remaining flap over the top

glaze:
- glaze with a beaten egg
- make fork holes along the top - to let out excess steam

bake:
- 180° C untill golden brown - approx 20 min

dobrou chuť :)
