How to Make The Best Pesto Ever

If you want to learn how to make the best pesto ever, see this pesto primer with tips on how to make the best,  most luscious pesto from your own garden in your own kitchen.

Pesto is one of the easiest of Italian recipes now that the food processor has been invented.  Of course, it’s a different story if you have to stand for hours smashing the ingredients into a paste (pesto in Italian) with a mortar and pestle like in days of yore–or in the kitchens of contemporary Ligurian/Italian chefs who are purists. There are, however, a few tips here that can make your pesto so much better.

Nowhere is pesto so sweet and delicious as that grown in Italy and Rome's Camp dei Fiori sells it by the bunch for very little money.

If the weather in your area is still warmish and your pesto is still going, now is the time to freeze a few portions of pesto to warm your soul during the winter months.

First, let me address anyone who lives on the eastern seaboard. I had a hard time growing basil this past summer. I only got a few batches of pesto out of my crop because  my crop kept dying on me and I couldn’t figure out why. After reading this recent article in the Washington Post (The Race To Save Sweet Basil), I now know there’s a blight that since 2007 has been making its way up the eastern seaboard and killing specifically the sweet basil. So don’t blame yourself, blame the vermin. Supposedly Rutgers University is working on breeding a sweet basil hybrid that will resist the fungus and may be available in about two years. I know, I know…we can’t wait that long!

 

How to Make the Best Pesto Ever

1. Start with good seeds if you grow your own. Your basil seeds or small plants should say Italian or Sweet or Classic or Genovese Basil. You can order basil seeds from Grow Italian on the Internet.  When picking leaves for pesto, choose the smaller, brighter leaves.

2. Soaking the leaves for ten minutes in ice water helps keep the bright green color during the preparation process and soaks out some of the leaves’ bitterness.  If you have the time, blanch the leaves for just 30 seconds in boiling water, then plunge them in cold water.  You don’t have to dry them completely before you start the pesto process.

3. Use fresh, good cheese in your pesto such as Parmigiano-Reggiano or an aged pecorino (but not Romano as it’s too salty) or a combination of the two.

4. To help make your pesto velvety, grate the cheese on a microplane so the fluffy cheese will melt right into the sauce.

5. Refrigerate your blender or food processor blade before making the pesto as this tempers the oxidation of the leaf and lowers the bitterness factor.

6. Never expose your pesto to heat on the stove top or in the microwave.  Either serve it just after you make it–or if refrigerated or frozen, thaw and let it come to room temperature before serving.  The heat will be there when you mix it with the just-cooked pasta.

7. Toss a few tablespoons of starchy pasta cooking water into your pesto to loosen it up before mixing it with pasta.

8. If refrigerating or freezing your pesto, pour a thin layer of olive on top to seal it. Also, many people keep the cheese out of any pesto headed for the freezer and wait until just before serving to add the cheese. Your call.

As you can see below in a pesto I made before I started researching best practices, my pesto is the color of an old army blanket we have downstairs. But now I know…and you know. I guess I should add a basic basil pesto recipe to this post in case you don’t have one. So…see below. And enjoy.

I didn't learn to make better pesto fast enough.  I didn't blanch or soak my pesto before making it in a food processor and pouring it over hot pasta, but it sure did taste delicious.
