Surprisingly, both cilantro and basil freeze very well. After cutting the leaves, preferably in the early morning while they are freshest, we mix them with a small amount of olive oil... just enough to coat the leaves. They are then packed into freezer bags and frozen for later use. The olive oil makes it really easy to separate the frozen leaves and also adds an extra flavor to the mix.
How to cut herbs - for basil don't pluck leaves off, instead trim stem. Leave two sets of leaves on stem (leaves grow in pairs across from each other). Cut immediately above the second set of leaves from the ground. Plant will then grow new branches from
That's cool. Herbs in "frozen" olive oil is one of my favorite ways to harvest. The herbs don't get dry , brown and brittle in the same way they do when they get frozen in water. They also retain their scent and flavor much more effectively!
