1) In a food processor pulse basil, garlic, parmesan cheese, salt
and pepper until smooth.
2) Slowly add the olive oil while pulsing.
Notes
1) Store in a sealed container and refrigerate until ready to use or
you can freeze this in ziplocks bags to use at a later date.
2) Add evaporated milk to soften taste and reduce use of olive oil.
3) Add sun dried tomatoes to make sun-dried tomato pesto. Make sure
that these are dried tomatoes and not the ones stored in olive oil
as it will change the texture of the recipe.
