What sort of Lemon do we have
We have moved into a home where there is a lemon tree growing in the backyard. The tree itself has large thorns and the fruit look like tear drop shapes with rough skin, but not as rough as a bush lemon. When cut, the juice seems to be clear but a little sticky, feels a little bit like the sap of oleanders but not white. The lemon itself tastes something like a lemon but has a bitterness which is not like a lemon. It has a bitter aftertaste.
