Notes
Store your sour cream dip in an airtight container in the refrigerator. It will last for 3-5 days. Stir well before serving. Unfortunately, like most dairy-based foods, this dip does not freeze well.The chilling step is crucial for the best flavor, so make sure to make this dip in advance. For the cleanest cuts when you are chopping chives, use either kitchen scissors or a very sharp knife. A dull knife will crush the chives rather than cutting through cleanly, and the chive dip won’t be as pretty when you stir it together.
