Purée cilantro leaves with the DGF relish in a food processor or blender, until minced as much as possible.
Add the mayonnaise and sour cream in a mixing bowl, followed by the ranch seasoning, garlic powder and salt. Mix well with large spoon or whisk.
Add cilantro/pepper mixture into the sour cream mixture, stir until well combined. Add the lime juice and mix again. If the mixture is too thick, add small amounts of buttermilk and mix until you get the desired consistency.
Store in an airtight container. Keep in refrigerator for up to one week. Best served after several hours allowing time for all the ingredients to blend/marinate.
Enjoy with tortilla chips and/or fritos.
