Authentic Spanish bistro chips: thick hand-cut Kennebec potatoes double-poached and crisped in Spanish extra virgin olive oil with sea salt.
Rinse cut potato batons in cold water to wash away surface starch, then dry thoroughly with clean kitchen towels.
Heat olive oil in a wide pan to 140°C. Cook potatoes gently for 10-12 minutes until soft inside without coloring. Remove with a slotted spoon and let cool 10 minutes.
Raise oil heat to 185°C. Return potatoes in batches and fry for 3-4 minutes until golden, blistered, and crunchy.
Drain on paper towels, toss immediately with coarse sea salt, and serve hot.
