Not just the Carolina's. That Peanut Coke thing was/is pretty widespread throughout the South. Works like midnight said. Our technique--as kids-- was to go to the corner store, buy an icy cold coke [it does have to be Coke], drink a couple of good sips to make room, then add a small bag of Planter's Salted Peanuts. The salt changed the flavor of the Coke, as well as partially de-fizzing it, and the Coke flavored the peanuts.
We did it all the time as kids, and I have hooked all my grandkids on doing it-except for the youngest [1 1/2 years]. For some reason her mom won't let me feed her peanuts:shock:
Here is another farm kid thing we did for an after scool treat. Pour a couple of good tablespoons of cold heavy cream into a cold bottle of Coke. Instant coke float. Watch the foam!!
