I got this recipe from Kelli. Thanks!
3/4 cup sugar
4 cups cold water
Cut lemons into thin slices, remove seeds. Place slices in a large non metal bowl; sprinkle with sugar and let stand 10 minutes. Press lemons with the back of a spoon to extract juice.
I actually got out my potato masher and gave them all a good squeeze. I got way more juice that I usually do just squeezing lemons into a pitcher.
Transfer mixture to a pitcher and add water. Stir and then remove lemons. Serve over ice.
