Green Sauce - Once Upon a Chef

Ingredients

• 3 jalapeño chili peppers, seeded if desired (I use about half the seeds for a medium-hot sauce), and roughly chopped (see note)
• 1 cup packed fresh cilantro leaves
• 2 cloves garlic, roughly chopped
• ½ cup mayonnaise, best quality such as Hellmann's
• ¼ cup sour cream
• 1 tablespoon fresh lime juice, from one lime
• ½ teaspoon salt
• ⅛ teaspoon freshly ground black pepper
• 2 tablespoons extra virgin olive oil
