Kettle-Fried Potato Chips with Sea Salt

Headnote

These chips are built on restraint: potato, oil, and salt, handled with precision. The result should be deeply crisp, clean in flavour, and evenly seasoned, with the natural sweetness of the potato preserved beneath the fry. Their character depends on thin slicing, controlled frying, and immediate salting while the surface is still receptive.

Ingredients

120 g potato, peeled

300 g vegetable oil

2 g salt

Method

1. Slice the potato into very thin rounds, 1 to 2 mm thick, keeping the slices as even as possible. Hold them in cold water for 5 minutes, then drain and dry thoroughly; the surface must be free of moisture before frying.

2. Pour the vegetable oil into a heavy saucepan to a depth of about 4 cm and heat to 175°C. Maintain this temperature throughout frying; the oil should shimmer steadily, not smoke.

3. Fry the potato slices in small batches for 3 to 5 minutes per batch, stirring gently at first so they do not cling together. They are ready when the bubbling has subsided, the colour is pale gold to light amber, and the edges are rigid and curled.

4. Lift the chips onto the paper-lined tray and season immediately with the salt while they are still hot. Toss lightly so the salt adheres evenly. Allow them to cool completely; they should become fully crisp and dry to the touch.

5. Weigh out 40 g of finished chips for service.

Plating and serving

Arrange the chips in a shallow bowl or small paper-lined dish, keeping them loose rather than compressed. Serve immediately, when the texture is at its most brittle and the seasoning remains bright.

Professional notes

Uniform slicing is the difference between elegance and excess oil. Drying the potato properly prevents splatter and gives a cleaner, more delicate crust. Salt must be applied the moment the chips leave the oil, or it will not bind with precision.
