A friend gave me a HUGE bag of lemons the other day. I love lemon in my water so I pulled out my old-fashioned juicer and started washing, slicing, and squeezing lemons. It took quite a while!
I strained the juice, put it in ice trays and popped them into the freezer. Later, the frozen cubes were transferred to a large zip top freezer bag and now every night I have a refreshing glass of ice water with fresh frozen lemon juice. It's quite a treat!
