Wash and dry the coriander.
Remove the stems and keep the leaves only (the stems make a good stock).
Place the leaves in some boiling water and blanche for 20 seconds.
Cool them down in an ice bath and place them in a blender along with the oils.
Blend at the highest speed until the oil smokes and turns very green.
Using a sieve with some kitchen paper on top, strain the oil into a bowl. If you can, do this in the chiller so your oil doesn’t lose its color.
Once the oil is done, using a smoking gun and a bell, fire up the coriander seeds and smoke the oil. Shake, smoke, shake again until the oil tastes very smoked.
Seal it in a small bottle.
If you don’t have a smoking gun, you can use your bbq or a pot. You just need to set the seeds on fire, place them next to the oil, and use a lid to trap the smoke in.
