Pesto Basics


Fat Guy

Recommended Posts

If anywhere near U Giancu in Rapallo (http://www.ugiancu.it), stop in for pesto, the best I've ever had. Chef Fausto also gives lessons, and is a wonderful character. Their version is with pasta, potato and green beans, a classic combination in Liguria.

With a reference version in mind, one has to go by taste. Pesto comes from both Nice and Genova, from when they were one region predating either France or Italy. The classic Ligurian recipe tends to be lightened with some fresh cheese, for which one can improvise liberally. Fausto has various booklets available from Europe; Ogni Volta Che Cucina calls for "4 bunches of basil; 2 cloves of garlic; 1 tablespoon of pine nuts; a handful of grated parmesan cheese; 5 tablespoons of olive oil; 100 grams of curd cheese; a little coarse salt."

Affordable pine nuts invariably come from China, with a liberal species definition leading to mild poisonings where everything tastes like metal for two weeks. (Google "pine mouth.") Use Italian pine nuts, which taste better, or substitute.

I vividly recall friends in Genova clutching bunches of basil from the market, for pesto. These were infant plants by U.S. standards. They delicately put it to me that pesto from my country tastes like lawn clippings, because of the enormous plants we use. One is supposed to grow the basil from seed, thinning for pesto until the thicket gets too large to use. In the California summer I ring half wine barrel planters with spray misting hose (as used to cool off outside) programmed through our garden irrigation system, to grow pesto basil from seed. We don't eat pesto out of season, though we do freeze basil in oil to make pesto for soupe au pistou.

Ligurians are also pretty adamant about using a mortar and pestle, which has a fundamentally different effect than a food processor. A Thai mortar and pestle (as popularized by Jamie Oliver, for example) is perfect.

How long can you, uh, keep good-n-oily pesto in the fridge?

 

Obvs I'm not talking about in your restaurants, I'm talking about at home. 

 

Tell the truth, y'all.  How long would you keep eating it?  Inquiring minds want to know. 

 

Well, maybe just this one specific inquiring mind over thisaway who put some very expensive nuts into an aforementioned good-n-oily pesto some months back, and somehow lost it in the back of the bottom shelf, and who really wants to eat it now that it has resurfaced and doesn't seem, you know, off or anything . . . .  

 

I mean, did I mention the generous layer of luscious oil?  Isn't that a kind of a . . . preserve?

 

Sigh.

I always refer back to fridge temps. I've kept grocery store fresh one for a couple weeks but rely on nose and taste.  I think the freshness of the significant herbal appeal deteriorates. Freezer may be better option.

I keep ground nuts in the refrigerator a long time.  However once made into pesto I'd expect the mix would go south pretty quickly.
