I've got two giant basil plants in the garden and winter is coming, so it's time to start harvesting them. I used to make pesto but that was work. Today I just brought in half of one plant, shown here,
pulled the leaves out, stuffed them into a plastic bag,
and put them in the freezer. If it's like spinach and other greens, you can crumble them while they are frozen and it even saves time chopping. So hopefully I'll have fresh-frozen basil throughout the winter.
