Mix together the sugar with the water, add the freshly squeezed lemon juice. Gradually heat the mixture on the stove while stirring nonstop.
Let the syrup come to a boil, boil 3-4 min. on medium heat and remove from the stove.
The resulting syrup is enough to syrup 1 large tray of baklava (for which you've used 2 packs of phyllo pastry sheets).
