I plant about 5-6 basil plants in the summer. When it is time to harvest the basil I make large batches of this Basil Pesto. Once you make your large batch simply pour into ice cube trays, mason jars, container of your choice. Freeze! Will last in your freezer for 6-8 months, although we have never let basil pesto stay in our freezer for more than 3 months since the kids are older and started loving it on their bread, sandwiches, pizza etc.
