If you enjoy Italian cuisine, you’ve probably encountered pesto at some point. This delicious sauce made from basil, pine nuts, Parmesan cheese, garlic, and olive oil can add a burst of flavor to pasta, sandwiches, pizzas, and more. However, if you’re making pesto at home, you may have noticed that it tends to turn dark after a while. In this blog post, we’ll explore some tips and tricks to prevent pesto from turning dark and maintain its vibrant green color.

Why does pesto turn dark?

Pesto turns dark due to a natural enzymatic reaction that occurs when basil leaves are exposed to oxygen. This reaction, called oxidation, causes the chlorophyll in the leaves to break down, resulting in a darker color. While this doesn’t affect the taste of the pesto, it can be visually unappealing.

How to prevent pesto from turning dark:

  • Blanching the basil: One effective method to prevent pesto from turning dark is by blanching the basil leaves before incorporating them into the sauce. Blanching briefly cooks the basil leaves and helps preserve their vibrant green color. To do this, bring a pot of water to a boil and immerse the basil leaves for about 20 seconds. Quickly cool them down in ice water and pat dry before using in your pesto.
  • Adding lemon juice: Acidic ingredients like lemon juice or citric acid can help slow down oxidation. By adding a squeeze of lemon juice to your pesto, you can prevent it from turning dark for a longer period. However, be cautious not to add too much lemon juice as it can alter the taste of the sauce.
  • Using airtight containers: Exposure to air accelerates the oxidation process. To preserve the vibrant color of your pesto, transfer it to an airtight container immediately after making it. Ensure that there is minimal air trapped inside the container to minimize oxidation.
  • Coating the top with olive oil: An extra layer of olive oil on top of the pesto can act as a barrier, preventing direct contact with air. After transferring the pesto to a container, pour a thin layer of olive oil on top before sealing it. This will help maintain the green color for a more extended period.
  • Freezing: If you’ve made a large batch of pesto and want to store it for an extended period, freezing is a great option. Freezing suspends the enzymatic reaction effectively, preventing the sauce from turning dark. Divide the pesto into small portions and store them in freezer-safe containers or ice cube trays for easy defrosting and portioning.

Quick tips:

  • Store pesto in the refrigerator and consume within 5-7 days for optimal freshness.
  • When using defrosted pesto, mix in a fresh drizzle of olive oil to revive the texture and flavor.

By following these simple yet effective tips, you can keep your homemade pesto looking vibrant and appetizing for longer. Enjoy your freshly made pesto without worrying about it turning dark!
