PESTO DI NOCI (Walnut pesto/ sauce for pasta)

I was discussing travelling in Italy and regional food (frequent topics of conversation) with an acquaintance, who told me that she and her daughter had really enjoyed travelling in Tuscany and had eaten a wonderful pasta dish with walnuts. She had no idea what it was; she had tried to work this out from recipe books but to no avail. She said that the sauce was very fragrant.

I think it must have been pesto di noci, very common in Liguria, home of pesto alla genovese (the one with pine nuts and basil).

I first ate this in Genova. My cousin Rosadele prepared this for me when I first visited her many years ago (to meet our respective, then husbands). Being autumn, she made this sauce to accompany agnolotti (pasta shaped like half moons/ hers were stuffed with ricotta and stracchino). She is a wonderful cook. Her mother, from Piedmont was also a very skilled cook, and between the two of them, there was always alchemy in their kitchens.

Although I promised this recipe to my acquaintance, I have been a little reluctant to post it in winter – it is made with fresh marjoram, and those of you who grow it and live in the colder states, will know that marjoram is dormant at this time of year. It hates hard winters and frost. However, if you have planted marjoram somewhere sheltered from the cold, and in a sunny location or even kept it indoors in a sunny spot, you may still have this herb. Taking one’s plant indoors is quite a common practice for people in England. My plant of marjoram, which was doing quite well on my balcony till about a month ago, now looks dead. I did check at The Queen Victoria Market this week to see if there were bunches of marjoram available, and there were.
Traditionally because it is a pesto, it is made with a mortar and pestle (see my recipe for Sicilian pesto), but I admit that with these ingredients a blender has worked well for me ( unlike basil which is likely to taste grassy if blended).

INGREDIENTS
walnuts, 500g
marjoram and parsley, 4 tablespoons of each, chopped
ricotta, 250 g
extra virgin olive oil, ¾ cup
garlic, 1-2 cloves
water, 1 tablespoon
salt, to taste
butter or thick cream, 2 tablespoons
grated nutmeg, a little
pasta, 400-500g (trofie – Ligurian, traditional shape)

PROCESSES
Blend walnuts, oil and garlic – add chopped herbs, salt and blend some more.
Add water and butter/ cream and pulse blender to the desired consistency.
Cook pasta.
Stir in the ricotta and nutmeg in the sauce.
Drain the pasta but reserve approx ½ cup of hot pasta water to stir into sauce just before serving (to warm the sauce).
Combine sauce with pasta and serve.

Grated parmigiano can be added – I prefer it without.

Do not get confused with oregano and marjoram (many do). The genus name for both is origanum. Marjoram (origanum majorana) is also called sweet marjoram or knotted marjoram. It has a softer leaf and stem, it is paler in colour, the flavour is milder, sweeter and it is very aromatic. Marjoram leaves are best when fresh.

Oregano is a very common herb in Sicily, but not marjoram – this herb is generally used only in the northern part of Italy.
