Prepare the syrup by boiling 2 and 1/2 glasses of water, the sugar and lemon juice for 2 minutes. Put aside. Melt the butter in a saucepan. Add 3 glasses of water and bring to a boil. Add a pinch of salt and the flour and keep stirring over a low heat for 10 minutes.

Remove from the heat and let it become warm, then stir the eggs in one by one. Oil your hands and take portions the size of walnuts from the mixture and fashion them into oval shapes. Make a slit down the center with your finger giving them the appearance of lips. Place the little pastries into the warm oil, cook them on a medium heat, then let them soak for 15 minutes in the cooked syrup.

Place them on a serving plate and top with fresh cream or crushed pistachio nuts.
