📝 About This Recipe

This vibrant, electric-green oil is the secret weapon of professional kitchens, offering a concentrated burst of fresh, oniony brightness and a luxurious mouthfeel. By flash-blanching fresh chives and rapidly cooling them, we lock in a stunning chlorophyll pigment that transforms ordinary dishes into gourmet masterpieces. It is a versatile, dairy-free finishing oil that adds both visual drama and a sophisticated aromatic depth to any plate.

🥗 Ingredients

The Aromatics

  • 200 grams Fresh Chives (roughly 2 large bunches, washed and patted very dry)
  • 30 grams Flat-Leaf Parsley (optional, for a deeper green hue)

The Oil Base

  • 1.5 cups Grapeseed Oil (or any neutral oil like canola or sunflower)
  • 1/4 teaspoon Fine Sea Salt (to enhance the herbal notes)

Blanching Essentials

  • 8 cups Water (for the blanching pot)
  • 4 cups Ice Cubes (for the shock bath)

👨‍🍳 Instructions

  1. 1

    Prepare an ice bath by filling a medium-sized bowl with cold water and a generous amount of ice cubes. Set this aside near your stove.

  2. 2

    Bring a large pot of water to a rolling boil. Do not add salt to the water, as we want to preserve the pure color of the herbs without drawing out moisture too early.

  3. 3

    Once boiling, submerge the chives and parsley into the water for exactly 15-20 seconds. You will see them turn a brilliant, vivid green almost instantly.

  4. 4

    Immediately remove the herbs using a slotted spoon or tongs and plunge them into the ice bath. This stops the cooking process and 'shocks' the color into place.

  5. 5

    After 1 minute in the ice bath, remove the herbs and squeeze them firmly with your hands to remove as much water as possible.

  6. 6

    Place the squeezed herbs onto a clean kitchen towel or several layers of paper towels. Pat them thoroughly until they are bone-dry; any residual water will make the oil cloudy and shorten its shelf life.

  7. 7

    Roughly chop the blanched, dried herbs into 1-inch pieces to help the blender blades catch them more easily.

  8. 8

    Place the herbs and the 1.5 cups of neutral oil into a high-speed blender. Add the pinch of sea salt.

  9. 9

    Blend on the highest speed for about 2 minutes. The friction from the blender will slightly warm the oil, which helps the fat-soluble pigments and flavors infuse into the liquid.

  10. 10

    Stop blending when the mixture looks completely pulverized and the container feels slightly warm to the touch (about 100°F or 40°C).

  11. 11

    Set up a fine-mesh strainer lined with a coffee filter or double-layered cheesecloth over a clean glass bowl.

  12. 12

    Pour the mixture into the filter and let it strain naturally. Do not press or squeeze the solids, as this will force pulp through and result in a cloudy oil.

  13. 13

    Once the oil has fully dripped through (this can take 30-60 minutes), transfer it to a dark glass bottle or an airtight jar.

💡 Chef's Tips

Always use a neutral oil; extra virgin olive oil has too strong a flavor and can turn bitter when blended at high speeds. Ensure the herbs are completely dry after the ice bath; moisture is the enemy of a clear, vibrant oil. Store the oil in the refrigerator to maintain its bright green color; it will stay fresh for up to 2 weeks. If the oil solidifies slightly in the fridge, let it sit at room temperature for 10 minutes before using. For the clearest possible oil, use a paper coffee filter for the final strain, even if it takes longer.

🍽️ Serving Suggestions

Drizzle over a creamy cauliflower or potato leek soup for a stunning color contrast. Use as a finishing touch on seared scallops or white fish to add a delicate onion aroma. Swirl into a bowl of dairy-free risotto or pasta just before serving. Mix with a little lemon juice to create a vibrant vinaigrette for heirloom tomato salads. Serve in a small dish alongside warm sourdough bread as a sophisticated plant-based appetizer.
