Basil Oil The Chefs Technique for Vibrant Emerald Green Infusion

Instructions:

1. Set Up the Stations: Bring 4 cups of water to a rolling boil in a saucepan. Simultaneously, fill the large bowl with the ice cubes and cold water (the 'ice bath').
2. Blanch the Basil: Submerge the basil leaves into the boiling water for precisely 10 to 15 seconds. Use a slotted spoon to gently push them down. The basil will immediately wilt and turn a brilliant, deep green.
3. Shock the Basil: Immediately transfer the blanched basil from the boiling water straight into the ice bath. This stops the cooking process and locks the chlorophyll colour. Leave for 30 seconds until completely chilled.
4. Dry Thoroughly (Crucial Step): Remove the basil from the ice bath. Squeeze the basil firmly to extract as much excess water as possible. For the best result, wrap the squeezed basil in a clean tea towel or paper towels and wring it out until it is virtually bone dry.
5. Combine Ingredients: Place the dried basil leaves, the neutral oil, and the salt into the high-speed blender.
6. Blend: Start blending on low speed, gradually increasing to the highest speed. Blend continuously for 1–2 minutes until the mixture is completely smooth and slightly warm to the touch.
7. Rest: Pour the warm basil mixture into a bowl and let it sit for 15–30 minutes to steep, allowing maximum flavour transfer into the oil.
8. Set Up Straining: Line the fine-mesh sieve with a double layer of cheesecloth or muslin and set it over a clean bowl.
9. Strain (Patience Required): Pour the blended basil oil mixture into the lined sieve. Do not press the solids (the pulp). Allow the oil to drip through naturally under gravity. This process takes 30–60 minutes for the clearest oil.
10. Store: Once the dripping slows to a crawl, gently gather the edges of the cheesecloth, discard the pulp, and transfer the finished basil oil to an airtight container or bottle.
