Hi, I wish to cut a lemon in half and save one half. what is the best way
to save that half? in a plastic bag in fridge, or can I freeze it and then
defrost it and still use a little at a time?

The other half of the lemon I wish to use immediately and just use a little
each day.

what is the best way to cut it and squeeze it? The often seen way of thin
segments squeezed between the fingers seems hard work. thanks
