1/3 C. kosher salt

6 C. fresh basil leaves, packed

2 C. extra-virgin olive oil

 

In a large saucepan, bring 4 quarts of water to a boil with the salt. Add the basil and cook for 15 seconds. Drain through a sieve and immediately plunge the basil into an ice water bath to stop the cooking process. When cool, drain again and squeeze all the water from the basil with your hands. Place the basil and the oil in a blender and pulse a few times to break up the herbs. Then blend for 2 minutes to puree. Strain the infused oil through cheesecloth or paper coffee filters. Transfer to a sterilized glass bottle or jar and cover. Refrigerate for up to 2 weeks.
