Cheddar and sour cream is a classic American chip flavour that pairs the sharp, salty taste of cheddar cheese with the cool tang of sour cream. Both are added as dried powders in the seasoning, often with onion or garlic for extra savour, and the pairing tastes creamier and tangier than cheddar alone.
The snacks in this category are American: Chip Thunder Chargin’ Cheddar & Sour Cream Rumble Potato Chips from Snyder’s-Lance, a ridged potato chip, and Doritos Extreme Zesty Sour Cream & Cheddar, a corn tortilla chip from Frito-Lay. The same flavour pairing works on both bases, which is why SeekSnack groups it as a flavour rather than a snack type.
Both seasonings are made from milk. For each flavour on its own, see cheddar and sour cream.
