This as actually a recipe for a lemon flavoured syrup as opposed to lemonade per se. I mean, who needs a recipe for lemonade, right? Juice a couple of lemons, put the juice in a glass, add about 3 tablespoons of sugar, fill with water, stir forever, and voila! The purpose of this recipe is to avoid the "stir forever" part, and to get more mileage out of your precious lemons. So onwards!
The basic recipe for this comes from The Joy of Cooking. There is a cool section in there on drinks, and sugar syrups is my favourite part of that section. I found their version to be a little to lean on lemonyness (someone call Oxford!) so I've modified it a little.
Lyncburg Lemonade if you are so inclined.)
