The first real basil pesto I ever tasted was at the Campionato Mondiale di Pesto al Mortaio in Genoa, on a Saturday in April when the Palazzo Ducale courtyard smelled like a garden had exploded inside it. Rows of marble mortars. Old men in aprons. A queue that curled back on itself twice.
I was staying at a tiny hostel in the Maddalena quarter that week, run by a woman named Chiara who cooked a batch of pesto every Sunday afternoon for whoever was still hanging around the common kitchen. She had told me to go to the championship. Actually she had insisted, pushed me out the door with a slice of focaccia in my hand and directions written on the back of a receipt.
The Courtyard in Genoa Where I Learned What Basil Pesto Should Taste Like
The competitors were locals mostly, plus a few pilgrims from as far as Argentina and Japan. Each one had ten small Genovese basil leaves, a fistful of pine nuts, two cloves of garlic, coarse salt, two aged cheeses, and Ligurian oil. That was it. They worked the mortar with a slow circular motion that looked almost lazy until you noticed the wrist strength behind it.
A retired sailor named Beppe let me taste his after he was eliminated in the second round. He shrugged, offered me the wooden spoon, and said something about his mother that I did not quite catch over the microphone feedback. The pesto was warm from the friction of the pestle and smelled like a hillside in July. Green, sweet, salty, faintly grassy.
I ate the rest of that day in a daze, walking through Pra’ where the sweetest basil in Liguria is grown on terraced hills that catch the sea light. That night I told Chiara I would never eat store-bought pesto again. She laughed at me. Fair enough.
Bringing the Recipe Back to My LA Kitchen
Recreating pesto alla genovese in a California apartment is a strange exercise. The festival version had things I could not pack in a suitcase. The noise of the crowd. The particular hum of Ligurian olive oil pressed the week before. Beppe.
I ordered a marble mortar the week I got home, a fat eight-inch one from an Italian import shop in Highland Park. It arrived heavier than I expected and now lives on my wooden kitchen table, the one that gets the morning light and a bit of jam residue no matter how often I wipe it.
For basil I drive to the Hollywood farmers market on Sunday and buy small young leaves from a grower who understands why I am picky. Large mature basil tastes of mint and hay, which is fine for a caprese but wrong for this. The pine nuts I buy Mediterranean, never Chinese. The Chinese ones can leave a metallic aftertaste on your tongue for days, and I learned that the hard way in 2019.
What I Changed and What I Refused To
A food processor would be quicker. I know. I will not use one for this. The blades bruise the leaves and generate enough heat to oxidise the oils, which is why supermarket pesto is that murky army green rather than the vivid uniform green it should be. Ratto wrote the first published recipe for pesto genovese in 1863 and he was pounding, not blending, and I am going to trust the man.
The one thing I have adapted is the cheese ratio. Real Pecorino Fiore Sardo is not always easy to find in LA. The Silver Lake cheese counter carries it sometimes, but if they are out I use a slightly higher proportion of Parmigiano Reggiano and a smaller amount of a young Sardinian pecorino I trust. It is not identical. It is honest.
What Goes Into It
- Two cups of young Genovese basil leaves, small ones only, stems off
- Three tablespoons of Mediterranean pine nuts
- Two garlic cloves, green germ removed so it does not turn bitter
- Half a teaspoon of coarse sea salt, which doubles as an abrasive
- Half a cup of Parmigiano Reggiano, aged around 30 months, finely grated
- Three tablespoons of Pecorino Fiore Sardo, finely grated
- Half a cup of Ligurian extra virgin olive oil, Taggiasca if you can get it
How I Actually Pound It
Dry the basil like your life depends on it. Wet basil turns the sauce watery and dark, and there is no coming back from that. Salad spinner, then a kitchen towel, then a moment of patience.
Start with the garlic and coarse salt in the mortar. Grind in circles against the wall, not straight down. About a minute, until it is a smooth cream with no visible chunks. Then the pine nuts, same motion, until they break into an oily paste.
Now the basil. A small handful at a time. Press the pestle sideways into the walls of the mortar and rotate. You are not smashing the leaves. You are coaxing them. I rotate the mortar with my other hand as I work, which feels awkward for the first thirty seconds and then feels obvious.
When every leaf is a bright green pulp, stir in both cheeses with the pestle. Then drizzle the oil in a thin steady stream, stirring constantly, until the sauce turns glossy but still shows tiny flecks of nut and leaf. Not a puree. Never a puree.
Small Twists and What I Will Not Change
Sometimes I boil small diced potatoes and trimmed green beans in the pasta water and toss the whole thing together, which is the classic Ligurian move and the reason the sauce feels creamy without any cream. It is a peasant combination and it is genius.
What I will not touch is the temperature. Never heat the pesto. The residual warmth of the pasta is plenty. A pinch of pasta cooking water loosens it into a proper coating. That is the whole trick.
I still miss the courtyard. The version I make on my table on a Sunday afternoon, windows open, is not the festival, and it never will be. But it is close enough that I understood, the first time I got it right, why Chiara pushed me out the door with that focaccia. Some sauces are worth pounding by hand.
Basil Pesto
Ingredients
Equipment
Method
- Rinse the basil leaves quickly in cold water, then dry them thoroughly in a salad spinner or by rolling them in a clean kitchen towel. Wet basil will not pound properly and will turn the pesto watery and dark.
- Place the peeled garlic cloves and the coarse sea salt in a marble mortar. Using a wooden pestle, crush and grind them with a circular motion against the mortar walls until you have a smooth, creamy paste with no visible garlic chunks, about 1 minute.
- Add the pine nuts and continue working them in with the same rotating pressure until they break down into a coarse, oily paste, about 1 to 2 minutes.
- Add the basil leaves a small handful at a time. Do not pound downward; instead, press the pestle against the walls of the mortar and rotate, crushing the leaves gently to release their oils without bruising them. Rotate the mortar with your other hand as you work. Continue adding basil in stages until every leaf is worked into a bright green pulp. This takes 5 to 8 minutes and should never feel rushed.
- Once the basil is fully broken down and the paste has turned a vivid, uniform green, add the grated Parmigiano Reggiano and Pecorino Fiore Sardo. Stir them in gently with the pestle until fully incorporated.
- Drizzle the Ligurian extra-virgin olive oil in a thin, steady stream while stirring continuously with the pestle. Work the oil in until the sauce is glossy, creamy, and homogeneous but still shows tiny flecks of basil, nut, and cheese. Do not overwork it into a smooth puree.
- Taste and adjust with a pinch more salt if needed. Use immediately at room temperature to dress hot pasta, tossing off the heat and thinning with a spoonful of pasta cooking water if the sauce feels tight. Never place the pesto over a flame.
