Sour Cream & Onion Potato Crisps

Headnote

These crisps are built for precision: a thin potato batter, seasoned with sour cream, onion, and a restrained salinity, then fried to a clean, brittle finish. Their character depends on balance rather than force; the dairy notes must read cool and tangy, the onion dry and savory, the texture light and exact. The result is a crisp that breaks sharply and dissolves cleanly, with no heaviness on the palate.

Ingredients

Crisp base

Dried potato: 70 g

Vegetable oil: 18 g

Corn flour: 22 g

Wheat starch: 18 g

Rice flour: 12 g

Maltodextrin: 8 g

Seasoning blend

Sour cream powder: 7 g

Onion powder: 6 g

Salt: 3 g

Monoglyceride: 1 g

Whey powder: 5 g

Yeast extract: 2 g

Natural flavor: 3 g

Method

1. Combine the dried potato, corn flour, wheat starch, rice flour, maltodextrin, sour cream powder, onion powder, salt, monoglyceride, whey powder, yeast extract, and natural flavor in a bowl. Mix thoroughly for 1 minute until the powders are completely uniform and no streaks remain.

2. Add the vegetable oil and work it through the dry mixture until the texture becomes evenly sandy and slightly cohesive. The mixture should hold together when pressed, without appearing greasy.

3. Bring the mixture together into a compact dough. If the dough resists, rest it for 5 minutes to allow the starches to hydrate and the surface to relax.

4. Roll the dough between two sheets of parchment to a thickness of 1.5 mm. Keep the sheet even; irregular thickness will produce uneven frying and brittle edges.

5. Cut the dough into crisp shapes of your choice, keeping the pieces small and consistent. Transfer them to a tray and let them stand for 5 minutes so the surface firms slightly.

6. Heat the vegetable oil for frying to 180°C. Fry the crisps in small batches for 2 to 3 minutes, turning once, until they are pale golden, rigid, and fully dry at the surface. They should sound sharp when tapped and show no soft centers.

7. Lift the crisps onto a wire rack set over paper towels. Allow them to drain for 2 minutes, then cool completely. As they cool, the texture should become fully brittle and light.

Plating and serving

Serve the crisps in a shallow bowl or on a narrow plate, gathered loosely rather than stacked tightly. Their surface should remain clean and matte, with the seasoning reading as a fine, even veil. The final impression must be crisp, savory, and precise.

Professional notes

Keep the dough thin and uniform; thickness is the difference between a crisp snap and a dense fry. The seasoning must be fully dispersed before shaping, or the flavor will land unevenly. Fry in controlled batches so the oil temperature remains steady and the texture finishes dry, not blistered or leathery.
