Knead flour, salt and a glass of water to a dough. Fold dough and knead again. Cover with a damp cloth and leave for some time.

Divide dough into 8-10 pieces. Spread starch on it and roll out as thin as possible. Place half of it into a pan, pouring margarine on each layer. Spread walnuts evenly on it and place the remaining layers with margarine between one upon the other. Cut into squares. Pour the remaining margarine evenly on the baklava. Bake in medium hot oven for about an hour.

In the meantime put sugar in a saucepan, cover with water, add one tablespoon lemon juice and boil to a heavy syrup. Pour it upon the lukewarm baklava, a little at a time, so that baklava absorbs the entire syrup. Serve cold.
