Pesto may have become popular in North America by the 1980's and 1990's however it is a recipe that apparently has been around for centuries. With its origins possibly dating back to the Roman age. Pesto originated in Italy, in the regions of Genoa and Liguria, and was first documented around the 1850's when basil became introduced as a main ingredient.
Previously mentioning our 2 foot basil plant helps and does lend itself to create this effortless purée; regardless this pesto recipe is not complicated to make, all thanks to using a speedy food processor. A herbaceous and tangy flavour with a balance of nutty earthiness and richness that clings when tossed with pasta. You may substitute the walnuts with another nut such as pecans or almonds or with the more traditional pine nut.
Basil Pesto
---------------------------------------------------------------------------------
1/3 cup walnuts pieces
2 large cloves of garlic, roughly chopped
2 cups lightly packed fresh basil leaves
1/2 teaspoon salt
1/4 teaspoon black pepper
2/3 cup extra olive oil
1/2 cup grated Parmigiano Reggiano cheese (not parmesan)
Using a food processor, chop the walnuts and garlic together.
Add the basil, salt and pepper until finely chopped
Keep the food processor running and add the olive oil.
Then add the Parmigiano Reggiano cheese until it's smooth.
Store in an air tight container with a thin layer of olive oil on top to prevent browning. The pesto will keep in the refrigerator for about a week or freeze for up to 6 months.
Notes: If you cannot find Parmigiano Reggiano cheese then use another cheese such as Pecorino Romano, Pecorino Sardo, Gana Padano or Parmesan.
