To play with this recipe
Increase the amount of basil (four times) and don't use olives or sun-dried tomatoes for a more classic green pesto. Add chives, ramps (!!), or fresh parsley for variations on herbaceous flavors. Substitute walnuts for cashews for a creamier buttery taste or almonds for a drier fresher take. Take out the fresh tomatoes and double or triple the amount of olive oil for a more traditional Italian version (too heavy on the vegetable fats for me, but deeeeelicious).
