Step 1: Mix ingredients
When you first mix them together the brown sugar will be grainy, brown specks in clearly white sour cream; after a short while the crystals will melt into the mix, forming a nice light-brown dip.
This dip can be made ahead of time and stored in the refrigerator; in fact it's preferable to give the flavors time to mingle.
Step 2: Serve
One of these divided dishes works well, though I'd recommend against this ungodly color of pink. Even if it's on sale, DON'T buy the pink one.
Store unused portion in the refrigerator; it should keep just under a week.
