I've got this recipe down to a "science"... uh, no. I have a very confident sense of the ingredients then adjust each time I make it :)
About 6 handfuls of basil. About 1-2 cups of extra virgin olive oil. Put it in the Food Processor until it begins to liquify. Then add the fun ingredients, beginning with toasted pine nuts. I leave them on the stovetop in a small pan for about 2-3 minutes until golden brown. (My preference is about a 1/4 cup) Add those to the food processor along with 1-2 ample squeezes of lemon juice, salt and pepper and a small clove of garlic. Let it blend for about 1-2 minutes. Taste, adjust seasoning as needed.
This recipe is perfect to put on an sandwich or wrap, as a salad dressing or even over pasta or with meat. The taste is strong so very little is needed. It refrigerates well so it can last a while :) On occasion, I'll add a bit of spinach or parsley to the ingredients or a splash free lemon or lime.
