Pesto Variations: Understanding Green Pesto and Its Ingredients
Green pesto is a versatile and flavorful condiment that can be made in various ways, using a range of ingredients. The dish typically features a vibrant green hue derived from fresh basil leaves, although it can be adapted to include different herbs and nuts. This article explores the different ingredients commonly used in green pesto and how they affect the final product.
What is Green Pesto Made Of?
When creating green pesto, the primary base is often fresh basil leaves. However, the recipe can be altered to use different herbs, such as arugula (rocket) or spinach, or even different types of nuts, such as cashews or pine nuts. While pine nuts are traditional in Genoese-style pesto, which is characterized by a rich, creamy texture, other nuts can be used based on personal preference or availability.
The selected oil is also crucial to the preparation of pesto. Olive oil, especially extra virgin olive oil (EVOO), is traditionally used but can be substituted with sunflower oil for a more affordable option. The combination of the green herbs and the oil results in a unique and flavorful condiment that can be used in various culinary applications, from pasta dishes to pizza toppings.
Adding cheese is another essential component. Cheeses such as pecorino, Parmigiano-Reggiano, or even Mozzarella can be used, depending on the budget and flavor profile desired. Canned cheeses or cheaper alternatives are sometimes used in mass-produced pesto to keep costs down, which can affect the overall quality and taste of the final product.
Quality of Ingredients and Cost Implications
The quality of the ingredients significantly impacts the taste and texture of green pesto. For instance, fresh herbs, high-quality nuts, and extra virgin olive oil will result in a superior pesto that is rich, creamy, and full of flavor. Conversely, using cheaper substitutes or mass-produced ingredients can lead to a lesser quality product that may not retain its freshness and texture well.
When it comes to commercial pesto, large-scale manufacturing often results in a product that is marketed at a lower price point. This can be attributed to the use of cheaper ingredients and mass production methods. As a result, mass-produced pesto from Italy, for example, may be sold for as low as $2 but lacks the depth and quality of its artisanal counterparts.
Maintaining the Green Color in Pesto
Preserving the vibrant green color of pesto is a challenge because the chlorophyll in the herbs can react with oxygen and turn brown. There are two effective methods to maintain the green color:
Blanching
How It Works: Blanching involves briefly boiling herbs in hot water, which inactivates the enzymes that cause browning. After blanching, the herbs are quickly cooled in ice water to stop the cooking process. This method minimizes flavor loss while effectively retaining the green color.
Instructions: Bring a pot of water to a boil. Submerge basil leaves in the boiling water for 30 seconds. Immediately remove the leaves and plunge them into a bowl of ice water. Dry the leaves thoroughly before proceeding with the pesto recipe.

Adding Lemon Juice
How to Use It: Another method to maintain the green color is to add lemon juice to the pesto. Lemon juice acts as an antioxidant, helping to preserve the pigment in the herbs and prevent browning.
Instructions: Once the herbs are pureed into a paste, drizzle in a little lemon juice. A few tablespoons will suffice to keep the color bright and green. Mix well to ensure the lemon juice is evenly distributed throughout the pesto.
Both methods are effective and can be used interchangeably to ensure that your green pesto maintains its vibrant, appealing color.
Flexible Herbs and Nuts for Pesto
While basil is the traditional herb used in pesto, the dish is incredibly versatile and can be adapted to suit different tastes and preferences. You can experiment with various herbs and nuts:
Hersbs: Basil Arugula (rocket) Spinach Herbes de Provence Cilantro
Nuts: Pine nuts Cashews Walnuts Pumpkin seeds
The key is to maintain the correct proportions of herbs and nuts to oils and cheese. This balance ensures a well-rounded and flavorful pesto that complements a wide range of dishes.
In conclusion, green pesto is a delightful and versatile condiment that can be customized to suit personal tastes and dietary preferences. By using high-quality ingredients and choosing the right method to maintain the green color, you can create a delicious and satisfying pesto that will add depth and flavor to your culinary creations.
