Authentic Basil Pesto Genovese

DSCN0353

The obvious perk of having a green-thumbed husband is that, wherever I turn in the garden, I am bound to stumble upon edible goodies. Even in the busiest time, when the work load and the chores of domestic life take over, I can always count of fresh, perfumed herbs. Whatever is in season, it is likely to be growing in our sunny backyard, ready for me to pick and transform into a nutritious meal. Turning emerald-green basil leaves into Italy’s most loved pasta condiment is an easy enough task, the ingredients are few and easy to gather, the method quite straight-forward; the only extra bit that will make the difference between a pesto and a really good pesto, is love and commitment to authenticity. Pesto is an ancient Ligurian dish and its name encapsulates the method used to produced it: in the Genoese dialect the word pestâ (Italian: pestare) means to poundto crush, in reference to the original method of preparation, with marble mortar and pestle, however it is acceptable these days to use a food processor. What has remained unaltered in times is the addition of boiled potato cubes and green beans, which elevate this humble dish to a delectable, substantial meal. Traditionally it is served with straccetti, trofie or trenette pasta, typical from the Liguria region of Italy, however spaghetti marries equally well with pesto and it is by far my dad’s desert island meal.

Papa’, this is for you!

INGREDIENTS, serves 4

2 large bunches of basil, stalks trimmed

2 ice cubes (they will help preserve the vibrant green hue of the basil)

1 garlic clove, peeled (use more if you like it very pungent)

3/4 cup of extra-virgin olive oil

1/3 cup of pine nuts

1/4 cup of grated parmigiano

1/4 cup of freshly grated pecorino

sea salt to taste

1 medium potato, peeled and cut into small cubes

1 cup of green beans, trimmed and cut into three

320 gr  (11 oz) of dry spaghetti

HOW TO

1. If using a food processor: put the basil, garlic, nuts, cheese and ice cubes in the bowl of a food processor fitted with blades and blitz until smooth.  Slowly add in the oil in a stream and process with the rest of the ingredients until dense and well emulsified. Taste for salt and adjust accordingly.

2. If using a pestle and mortar, add basil, garlic pine nuts, ice cubes and a pinch of salt to the mortar. Start working with the pestle, pressing and rotating it until all the ingredients are nicely ground. Add the cheese and mix well. Slowly pour in the oil and mix well until well emulsified. Taste for salt and adjust accordingly. Discard the ice cubes that have not melted into the pesto. Set aside in the fridge until ready to use (it will keep, well covered in oil, for over a week).

3. Bring a large pot of slated water to the boil. Drop in your pasta along with the potato cubes. 4 minutes into cooking, add the beans. Cook your pasta and vegetables until nicely al dente. Drain, but be sure to reserve 3  or 4 tablespoon of pasta cooking liquor (aqua di cottura). Place the pasta, potato and beans onto a serving dish, pour over the pesto and mix well. If too dry, add a little of the reserved cooking water.

Serve piping hot!
