Herbed Finishing Oil
Infuse a neutral oil with fresh herbs by gently heating them until the color brightens, then straining the oil to capture the essence of the garden for drizzling over cooked proteins, roasted vegetables, or toasted sourdough.
Control the heat to preserve the life of the herbs.
If the oil gets too hot, the herbs will brown and taste fried rather than fresh; keep the temperature steady and low.

Maintaining the vivid green
Briefly dunking the herbs in boiling water for ten seconds before drying them thoroughly ensures the finished oil stays bright, vibrant green instead of turning a muddy olive.
The method.
Prepare the herbs
Bring a small pot of water to a boil. Submerge the herbs for 10 seconds, then immediately plunge them into a bowl of ice water. Dry them completely on paper towels.
Infuse the oil
Combine the oil and dried herbs in a saucepan over medium-low heat. Warm the oil to 150°F; do not let it simmer or bubble.
Strain
Let the mixture sit for 15 minutes off the heat. Pour through a sieve lined with a double layer of cheesecloth, pressing lightly on the solids to extract the green oils.
Store
Pour into a clean glass jar and refrigerate. The oil will stay vibrant for about one week.
Other turns to take.
Spicy Chili Oil
Add one teaspoon of red pepper flakes to the oil during the warming step.
Garlic Infusion
Add one smashed clove of garlic to the oil while it warms, but remove it before straining.
When it doesn't go to plan.
Always pat the herbs bone-dry after the ice bath; any water left on them will cause the oil to splatter and shorten its shelf life.
If you lack a thermometer, look for small wisps of steam rising from the oil; that is your signal to remove it from the heat.
Use this oil at room temperature, not straight from the fridge, to ensure the best aromatics.
The ones that keep coming up.
Can I use dried herbs?
Dried herbs do not work for this method; this technique relies on the water content and volatile oils found only in fresh plants.
How do I know if it has gone bad?
Trust your nose. If the oil smells rancid or like old pantry oil rather than fresh greens, discard it.
