Lemon jam

I must be crazy, but on my day off I'm making jam. I bought the lemons over a month ago intending to make this, and now it's my last chance before a) it's too late to give as Christmas gifts and b) the lemons go bad.

The recipe I found uses metric measurements, isn't totally specific, and uses more lemons than I have. So it's a bit scary, but I'm estimating how much sugar and water to use. Even if it's a flop, though, the lemons smell so good that it's not going to be a waste.

And now while the lemons are boiling, I'm going to have second breakfast and read.
