How to make sweet and sour?

Is it possible and/or desirable to make one's own sweet and sour with sugar and lemons? I don't like the idea of using something made with juice that's been sitting on a shelf for a couple of months. If anyone makes their own, do you have a recipee?

Found this by using the Search feature:

Juicers for tiki drinks

Thanks, Utopian. I'll give that one a try. Sounds easy.

Thanks for that, I wondered what the recipe was, I've been guessing so far.

I found this one in the book "Tiki Drinks"

Since sweet and sour is basically sugar, water, lemon or lime; this recipe fits. Best part you can keep the frozen cans on hand for impromptu parties.

1 can frozen limeade
1/2 can frozen lemonade

Mix and add water as directed from one of the cans (as if you where making one
batch of lemonade)

Use leftover lemon aid for other drinks.

Works for me, cost about $1
