Grandma's Apple Pie {light}

I loved my great grandmother a lot. She was my inspiration since I was a kid. She lived a difficult, but interesting life. I still remember her exciting life stories that she would tell me...and the older she got the more often she would repeat them over and over again:)
Whenever I would visit her, she would have something tasty to snack on. And this apple pie  I remember very well. It was always juicy, fragrant and so very tasty!
Luckily, I have her recipe saved and today I'm making this pie for my kids.
The dough contains cottage cheese, which makes it very soft with a little crunchy crust.  I reduced amount of butter from 1 cup to 4 tb.s. and I loved the result. Be generous and use a lot of apples (but be sure to use juice and sour sweet type), because this is the most important part!:)
1 1/4 cup low fat cottage cheese
1 egg
1 cup sugar
10g baking powder
pinch of salt
1t.s. lemon juice
4 tb.s. soft butter
2 cups flour
egg wash for the top
Preheat oven to 180C. Beat butter with sugar, add an egg. Sift flour and carefully add to the liquid mixture. Add baking soda and lemon juice. Then carefully combine and divide the dough into 2 parts, one bigger than the other.
Roll bigger part of dough into square and transfer it into 20x20cm greased baking dish, creating walls as well, but they should not be high.
Divide another part of dough into 6 and prepare stripes to make lattice top.
Filling
4 large sour sweet apples, cored, cut into cubes
about 1/2 cup sugar
1t.s. cinnamon
Mix everything together and let it sit for some 20 minutes, so that the apples begin to give their juice. Or you could microwave this mixture on high for 5 minutes or so.
Place apples over the dough and cover them carefully with stripes of dough. Brush with beaten egg.
Bake for 40 minutes. They are easier to cut when cooled...although the cake is very delicious when warm!
