First take the husks from the corns and toast them slightly with a blowtorch. You can also do this on a barbecue. This will create a really nice smoky flavor.
Now place the husks in a vacuum bag and also add the neutral oil. Vacuum this 100%. After that steam it at 85 °C for 50 minutes. You can also use a sous-vide for this.
Then let the husks drain on a fine sauce sieve and use a ladle to press out any oil so you don’t waste a single drop.
Transfer the lovage leaves into a blender and also add 300 grams of the husk oil.
Blend this till the temperature of the oil is 65 °C. It will heat up from the friction.
Then let it drain on a sieve that’s lined with a kitchen paper to clarify it. Do this in your fridge so the oil doesn’t turn brown.
