Prep Ice Bath: Prepare a bowl of ice water.

Step 2

Blanch: Bring a pot of water to a boil. Place basil leaves in a colander, then dunk the colander into the boiling water, using a spoon to ensure all basil leaves go under the water. Blanch for about 15 seconds, or until bright green and wilted.

Step 3

Ice Bath: Immediately transfer basil leaves to the ice water to stop the cooking process.

Step 4

Blend: Strain basil from water, patting dry. Add to a blender along with oil, blending until smooth.
