Harvest the top 2-3 inches of your basil plants in the morning, before the sun's heat drive oils back down into the plant
Bring fresh basil indoors and rinse if you're worried about bugs or dirt
Weigh out 200 gm (about 10 cups of loose basil leaves/stems)
Set aside
Peel 12 garlic cloves and set aside
Pour 1 C of olive oil into your kitchen blender
Add 1 teaspoon of salt
Drop 6 garlic cloves into the oil
Divide your fresh basil in half and place half in the blender
Fasten blender lid into place and pulse to start breaking up basil and garlic cloves
Once things have been broken up, puree for about 20-30 seconds or until you're happy with the consistency of your sauce
Use a spatula to pour your sauce into 4 oz (125 ml) jars, leaving 1/4 inch of head space at the top
Carefully top your jars with olive oil, being sure to cover the sauce
Tightly fasten a lid into place and label
Repeat the process with the remaining half of the basil, measuring in 1 C olive oil, 1 teaspoon of salt and 6 garlic cloves in your blender. Stuff basil on top of these ingredients and puree
Finish filling jars, top with oil, lid, label and freeze for 8-12 months
