For the Haricots Verts:

• • 1 pound Haricots Verts (French Green Beans), trimmed: Haricots verts, or French green beans, are slender and more tender than regular green beans. Look for bright green, firm beans with a smooth texture. Trimming the stem end of each bean is necessary for a more refined presentation and eating experience.

• • 1 tablespoon Olive Oil (for blanching, optional): A touch of olive oil in the blanching water can help to retain the vibrant green color and add a subtle richness. This is optional but recommended for the best visual appeal.

• • Salt (for blanching water and seasoning): Salt is essential for seasoning the blanching water and enhancing the natural flavors of the haricots verts.

• • Ice Water Bath: A bowl of ice water is crucial for immediately stopping the cooking process after blanching, ensuring the haricots verts remain crisp and retain their bright green color.

For the Green Goddess Dressing:

• • 1 cup Mayonnaise (good quality, full-fat or light, depending on preference): Mayonnaise forms the creamy base of the Green Goddess dressing. Choose a good quality mayonnaise for the best flavor. You can use full-fat for a richer dressing or light mayonnaise for a slightly lighter version.

• • 1/2 cup Sour Cream (or Greek Yogurt for a tangier and lighter option): Sour cream adds tanginess and depth of flavor to the dressing. Greek yogurt can be used as a lighter and tangier substitute.

• • 1/4 cup Fresh Parsley, roughly chopped: Fresh parsley provides a bright, herbaceous, and slightly peppery flavor that is essential to Green Goddess dressing. Flat-leaf parsley (Italian parsley) or curly parsley both work well.

• • 1/4 cup Fresh Chives, roughly chopped: Fresh chives add a mild oniony and delicate flavor that complements the other herbs in the dressing.

• • 1/4 cup Fresh Tarragon, roughly chopped: Fresh tarragon is a key ingredient in Green Goddess dressing, providing a distinctive anise-like and slightly sweet flavor. Fresh tarragon is crucial for authentic Green Goddess flavor; dried tarragon is not a suitable substitute.

• • 2 tablespoons Fresh Lemon Juice: Freshly squeezed lemon juice adds essential acidity and brightness that balances the richness of the mayonnaise and sour cream and enhances the herbal flavors. Avoid bottled lemon juice for the best taste.

• • 2 tablespoons White Wine Vinegar: White wine vinegar adds another layer of acidity and complexity to the dressing, complementing the lemon juice.

• • 2 Anchovy Fillets, finely minced (optional, but highly recommended for authentic flavor): Anchovy fillets add a savory umami depth to the Green Goddess dressing that is characteristic of the classic recipe. If you are vegetarian or prefer to omit anchovies, you can use a pinch of sea salt and a few drops of Worcestershire sauce (check for anchovies if strictly vegetarian) or soy sauce to add umami flavor.

• • 1 clove Garlic, minced or grated: Fresh garlic adds pungency and depth of flavor to the dressing. Mincing or grating it ensures it blends smoothly into the dressing.

• • 1/4 cup Extra Virgin Olive Oil (optional, for thinning and richness): A touch of extra virgin olive oil can be added to thin the dressing slightly and add extra richness and flavor. This is optional depending on your desired consistency.

• • Salt and Freshly Ground Black Pepper, to taste: Salt and freshly ground black pepper are essential for seasoning the dressing and enhancing all the flavors.
