Look For my second book coming out this spring.  All you need to know about gardening.

1)Pick fresh basil in the morning while the oils are at the fullest.

2) wash them and then put them in a food processor with a little
butter or oil and give it a whirl.

3) pour it into ice cube trays and freeze. After frozen put into
freezer bags and freeze. If you use oil or butter in the above step
and not water you can use them for just about anything.

Another method
Lay clean basil on a cookie sheet and put in the oven and dry them. I
have a gas oven so i just leave the pilot to do its work during the
night. I then put into a pint jar in my spice section.
