Simple syrup: Place the sugar and water in a small saucepan and stir so that the sugar dissolves completely.
Juice the lemons: Juice your lemons. Depending on the size two or three lemons would be needed.
Combine lemon juice, simple syrup: Pour the juice and the simple syrup sugar water into a serving pitcher. Add more water if you would like it to be more diluted (though note that when you add ice, it will melt and naturally dilute the lemonade).
