What food product is commonly paired with sour cream in baked potato salad?

Bacon is commonly paired with sour cream in baked potato salad because it adds a savory, crispy texture that complements the creaminess of the sour cream. The rich flavor of bacon enhances the overall taste profile of the salad and elevates the dish, making it more appealing and satisfying. The combination of flavors—salty and smoky from the bacon paired with the tangy sour cream—creates a well-rounded balance that is popular in recipes for baked potatoes and similar dishes.

While pickles, carrots, and onions can also be used in various salads, they do not traditionally pair with sour cream in the context of baked potato salad as effectively as bacon does. Pickles might introduce a tangy flavor, carrots add sweetness and crunch, and onions can provide sharpness, but none of these ingredients deliver the same level of contrast and fullness that bacon contributes when combined with sour cream.
