Cilantro-Walnut Pesto


1 cup walnut pieces

2 cups cilantro leaves, washed, drained and stemmed

1 green jalapeno pepper, seeded and chopped (optional)

1 teaspoon salt, or to taste

2 tablespoons cider vinegar


Put the walnuts in a food processor and grind them fine.

Add the cilantro, jalapeno peppers, salt, vinegar and 2 to 3 tablespoons of water to blend.  Blend in a little more water if necessary to make a thick sauce.  Taste and correct the seasoning, adding more salt if necessary.
