Mix soften butter with brown sugar, vanilla sugar, lemon juice and water in a bowl. Add two eggs and sifter flour to a mixture. Mix everything together in a bowl. (You can use gloves to make a dough). Place in the freezer.
Roll out the dough. Grab a baking pan, place a baking paper inside the pan, then transfer a pie layer into a pan. Add strawberry jam on top of the dough. Slice the rest of fresh strawberries, add a little bit of sugar to them, mix and add them on top of the jam.
