In a blender or food processor add your seeded jalapenos. Then pulse the blender a few times just until the jalapenos are broken up into chucks.

Add cilantro and pulse a few more times until your peppers and cilantro are broken up.

Add sour cream, ranch mix, and the juice from the lime. Blend until mixture is completely incorporated.

Serve chilled. I think this is better the next day when the flavors have had time to meld together, but it can be served immediately.
