How Much Garlic Should Pesto Have?

The Role of Garlic in Pesto

Garlic's inclusion in pesto is a matter of personal preference and varies by cultural and geographical influence. Throughout history, garlic has been primarily used to mask the smell of rotting meat, serving as a natural preservative. However, in modern cooking, garlic is a key ingredient for enhancing the herb flavors in pesto without overpowering the dish.

In Genoa, the amount of garlic used is closely related to the basil leaves. For a bunch of about 40 to 60 basil leaves, and to serve six people, one to three cloves of garlic are typically added. In my recipe, I use 2 small cloves or a bigger one, along with 30 grams of grated Sardinian pecorino, 30 grams of pine nuts, and enough EVO oil to cover the pesto jar by about 2 cm. In the Nice surrounding areas, they use a minimum of 3 cloves and up to 5 for their Pistou.

Opinions on Garlic in Pesto

There are varying opinions on the amount of garlic to use in pesto. Some prefer just a hint of garlic, while others like a more pronounced amount. A neighbor from the Gasparinos family, known for their whole neighborhood experiencing their garlicky aroma, serves as a humorous example of extreme garlic use.

It is generally advised to start with a small amount and taste as you go, adjusting according to your preference. Roasted garlic can be a great alternative for those who want a rich flavor without the sharpness. If you prefer it, garlic powder can be added, but fresh garlic is always better.

Conclusion

There is no one-size-fits-all answer to how much garlic a pesto should have. The best approach is to let personal taste guide you. The goal should be to enhance the flavors of the herbs and other ingredients, rather than overpowering them. It's also worth considering that other ingredients in your dish or salad might already have a garlicky flavor, so it's important to go easy until you know.

Regardless of the amount, garlic in pesto is about striking the right balance. One should aim to create a sauce with a unique aroma and taste that can be enjoyed by many. Garlic is never the only feature in a good pesto; it is just one of the key flavors. Never overdo it!
