How to Select the Best Basil for Making Pesto

Basil is the soul of pesto, and choosing the right one will make the difference between a good pesto and an extraordinary one. Here are the secrets to selecting the best:

Aroma and Freshness

When touching or breaking the leaves, they should release an intense and sweet aroma. If they don't smell, keep looking.
The leaves should be firm and crisp to the touch, not soft or sticky.

Visual Appearance

The leaves should be small, with an intense bright green color. Avoid spotted or yellowish ones.
The stems should look fresh and firm, not dark or wilted.

Correct Variety

Genovese Prá basil is the premium variety, grown near the sea of Genoa.
If you can't find this variety, any fresh Genovese basil will be a good option.

Season and Origin

The best basil is found in summer when it's at its peak.
Prefer locally grown basil or from nearby gardens for maximum freshness.

With these basic tips, you now have the necessary tools to choose the best basil and create an exceptional pesto.

Different Types of Nuts for Pesto: Which is the Best?

Although traditional pesto is made with pine nuts, there are excellent alternatives that can give equally delicious results and are more economical. Here are the best options:

Pine Nuts (Traditional)

They are the classic choice for Genovese pesto, providing a mild and delicate flavor.
Their main disadvantage is the high cost and that they become rancid quickly.

Almonds

They give the closest taste to the original recipe.
Perfect for making Sicilian pesto, providing a creamy texture.

Walnuts

They add a subtle and slightly sweet flavor to pesto.
They are an excellent economical alternative and easy to find.

Other Recommended Nuts

Pistachios: provide an intense and slightly sweet flavor.
Hazelnuts: excellent for pestos with a different touch.
Cashews: add creaminess and a mild flavor.

Nut-Free Alternatives

Sunflower seeds: perfect for those who cannot consume nuts.
Pumpkin seeds: a nutritious and economical option.

Important tip: To enhance the flavor of any nut you choose, lightly toast them before using. This will release their natural oils and improve the final flavor of the pesto.

Essential Ingredients for Authentic Pesto

A traditional pesto requires few ingredients, but each plays a fundamental role in achieving that characteristic flavor we all love:

Fresh Basil: 2 cups of fresh leaves that provide that intense aroma and characteristic flavor that defines the essence of pesto.
Extra Virgin Olive Oil: 1 cup that provides that silky texture and that essential Mediterranean touch that makes pesto unique.
Pine Nuts: 1/4 cup that provides that creamy texture and mild flavor so characteristic of traditional pesto.
Parmesan Cheese: 1/2 cup that adds that salty and deep touch that makes pesto unique and delicious.
Garlic: 2-3 cloves that add that punch of intense and aromatic flavor characteristic of pesto.
Salt: To taste, which provides balance and enhances all the flavors of the other ingredients.

How to Make Creamy Pesto, Step by Step

To achieve a creamy and delicious pesto, we'll follow these steps using the ingredients mentioned earlier:

Step 1: Ingredient Preparation

Carefully wash the 2 cups of basil leaves and dry them completely with paper towels to prevent oxidation.
Peel the 2-3 garlic cloves and cut them into small pieces to facilitate processing and even distribution.

Step 2: Initial Processing

Place the garlic in the food processor and pulse briefly to chop it finely without turning it into paste.
Add the basil leaves and process until finely chopped but still maintaining some texture.

Step 3: Adding Nuts

Add 1/4 cup of pine nuts and process until incorporated, maintaining some texture to give body to the pesto.
Scrape down the sides of the processor to ensure all ingredients blend uniformly.

Step 4: Adding Cheese

Gradually incorporate 1/2 cup of grated parmesan cheese while the processor is running.
Process until the cheese is completely integrated with the other ingredients.

Step 5: Oil Emulsion

With the processor running, slowly pour the cup of olive oil in a thin, steady stream.
Continue processing until you achieve a creamy and homogeneous mixture, without over-processing.

Step 6: Final Adjustments

Taste and adjust salt as needed, processing briefly to incorporate.
If you want a creamier pesto, add an additional tablespoon of olive oil until reaching the desired consistency.

Step 7: Serving and Presentation

Serve immediately over hot pasta, mixing well so the heat activates the aromas.
For other preparations, let it rest for 10 minutes before using so the flavors integrate perfectly.
If you want to store it, place it in an airtight jar with a thin layer of oil on top and refrigerate for up to 5 days.

Now you have a creamy and delicious pesto ready to use. Remember that freshly made pesto will always have better flavor and aroma than stored pesto.

Tips for Achieving the Perfect Pesto Texture

The ideal pesto texture should be creamy and homogeneous. Here are the most important tips to achieve it:

Emulsion Process

Add the olive oil in a thin, steady stream while processing to achieve a perfect emulsion.
If the mixture is too thick, gradually incorporate more olive oil until reaching the desired consistency.

Processing Technique

If using a food processor, don't over-process to prevent heating and oxidation.
When using a mortar, gently rotate your wrist "caressing" the ingredients against the walls instead of crushing them.

Temperature and Order

Process first the garlic with salt, then pine nuts, followed by basil, and finally the cheese.
Use ingredients at room temperature for better integration.

Final Adjustments

Reserve some pasta cooking water to adjust consistency if needed.
For a creamier pesto, add an additional tablespoon of oil and mix briefly.

Ideal Consistency

The final texture should be smooth but with some texture, not completely smooth.
It should be thick enough to adhere well to pasta but not so thick that it forms lumps.

How to Properly Store Pesto

There are different methods to preserve your pesto and maintain its freshness and flavor for longer. Here are the best options:

In the Refrigerator

Store the pesto in an airtight glass jar and cover it with a thin layer of olive oil to prevent oxidation.
In the fridge, it can last up to 5-6 days while maintaining its freshness and flavor.

In the Freezer

Pour the pesto into ice cube trays and cover with a thin layer of olive oil.
Once frozen, transfer the cubes to an airtight bag, and they can last up to 3 months.
For this option, it's better not to add the parmesan cheese until ready to use.

Vacuum Sealing

Use sterilized and airtight glass jars.
Fill the jars with pesto, seal them, and boil them completely covered in water for 30 minutes.
This technique allows you to preserve pesto for up to 5-6 months in a cool, dark place.

Important Tips

To thaw, place the cubes in the refrigerator the night before.
Always label containers with the preparation date.
If you notice changes in color, smell, or taste, it's better to discard it.
