Use this easy recipe for cilantro oil when making our Crab Cakes.
Place the cilantro leaves and stems and the olive oil in the bowl of a food processor. Pulse until the mixture forms a puree. Transfer the puree to a medium bowl, and let stand at least 3 hours or overnight.
Set a fine sieve over a small bowl, and pass the puree through the sieve. Discard any remaining solids. Store the puree in an airtight container, refrigerated, up to 2 weeks.
Bring this oil to room temperature before using. You can also use it as a substitute for butter in mashed potatoes.
