History of lemonade

Here's an interesting piece about the history of lemonade.

The trade in lemon juice was quite considerable by 1104. We know from documents in the Cairo Geniza--records of the medieval Jewish community in Cairo from the tenth through thirteenth centuries--that bottles of lemon juice, qatarmizat, were made with lots of sugar and consumed locally and exported.

I tend to look up every little thing when I'm writing because I don't trust my brain. I would hate to write something and then find out that lemons were secretly developed by a lime grower in Florida in 1864...

In other words I had my surgery today and it went well. I'm in some pain and my throat is sore and irritated from throwing up a lot and having a tube down it but other than that so far so good. More details later.
