Ridged Sour Cream and Onion Potato Chips

Headnote

These chips are built for precision: a clean potato base, a disciplined fry, and a seasoning that lands in layers rather than in one blunt note. The ridges give structure, carrying the sour cream and onion profile with greater grip and a more persistent finish. The result should be crisp, dry, and sharply seasoned, with enough acidity to lift the richness of the oil.

Ingredients

Potato, peeled and sliced into ridged chips: 17.0 g
Vegetable oil: 12.0 g

Sour cream seasoning:
Onion powder: 0.5 g
Salt: 0.4 g
Sugar: 0.3 g
Garlic powder: 0.2 g
Black pepper, finely ground: 0.1 g
Parsley, dried and finely rubbed: 0.1 g
Citric acid: 0.1 g
Lactic acid: 0.1 g
Yeast extract: 0.1 g
Milk powder: 0.1 g

Method

1. Prepare the seasoning in a small bowl by combining the onion powder, salt, sugar, garlic powder, black pepper, parsley, citric acid, lactic acid, yeast extract, and milk powder. Stir until the blend is uniform and free of visible clumps. Set aside.

2. Slice the potato on a ridged mandoline into even chips, keeping the thickness consistent so they cook at the same rate. Rinse briefly in cold water until the surface starch is reduced, then drain thoroughly and pat completely dry. The slices must feel dry to the touch before frying.

3. Heat the vegetable oil in a small saucepan or deep fryer to 175°C. The oil should be fully hot but not smoking.

4. Fry the potato slices in a single layer, in batches if necessary, for 2 to 3 minutes, turning once, until the chips are pale gold, rigid, and the bubbling has nearly subsided. They should sound crisp when lifted and show defined ridges without darkening.

5. Remove the chips with a spider or slotted spoon and drain on paper towels for 30 seconds. While still warm, transfer them to a bowl and sprinkle over the seasoning blend in a fine, even layer. Toss gently until every ridge is coated and the surface appears matte and evenly seasoned.

6. Spread the chips on a tray and allow them to stand for 1 minute so the seasoning settles and the texture firms completely. The finished chips should be dry, crisp, and delicately aromatic, with a clean sour cream and onion finish.

Plating and serving

Arrange the chips in a shallow mound or a narrow fan, preserving their ridged profile. Serve immediately while the seasoning is vivid and the texture remains brittle and light.

Professional notes

Dryness before frying is decisive; any retained moisture dulls the crust. Season the chips while warm so the powders adhere without clumping. Keep the fry pale: the flavor should read as clean potato, sharp dairy acidity, and onion, not as browned oil.
