Someone appeared with a giant

Someone appeared with a giant box of Lisbon lemons so I spent last night making a megabatch of limoncino. To make limoncino you let the zest from 5 lemons steep in the sun in 2 1/8 cup of vodka or grappa for 8 days, then you filter it and sweeten it with a syrup made from 2 1/2 cups sugar and 2 cups water and color it if you want it yellower. Then you bottle it and let it sit in the dark for a month. Then you store one bottle in the freezer and serve it after big meals.

So, the question is: what do I do with all that juice. I made Italian soda syrup, Melanie is making lemon curd, I am freezing some. But there is still a lot of lemon juice. Does anyone have any ideas? I might make ceviche Friday.

Needless to say, peeling and cutting away pith from lemon zest kept me from the Kyrie, and there is the Dante Readers' meeting tonight, so there will be a slight delay.
