In a medium bowl, add the sour cream, mayonnaise, salt, pepper, garlic granules, onion granules, ground cumin, cayenne pepper, and one tablespoon of minced chives.
Mix with a rubber spatula until all the ingredients are fully combined and the dip is smooth and fluffy.
Transfer the dip to a serving bowl and top it with the remaining chives.
Serve the dip immediately, or let it rest for 30 minutes before serving to allow the flavors to meld.

Notes
I like the texture and flavor of garlic and onion granules better than the powders. However, if what you have on hand is the powders, that's fine too.
If you like spicy food, feel free to increase the cayenne to ¼ teaspoon.
For the creamiest texture, drain the liquid from the top of the sour cream after you open the container.
You can keep the leftovers in an airtight container in the fridge for up to four days. Remove the dip from the fridge 30 minutes before serving it. I don't recommend freezing this dip.
