01 - Using a mandoline slicer or a sharp knife, cut the scrubbed potatoes into thin, even slices approximately 1/8 inch thick. Uniform thickness ensures consistent crispness during frying.
02 - Submerge the potato slices in a bowl of cold water for 10 minutes to draw out excess surface starch. Drain thoroughly, then pat each slice completely dry with paper towels—moisture is the enemy of crispiness.
03 - Pour vegetable oil into a deep fryer or a large heavy-bottomed pot to a depth of at least 2 inches. Heat the oil to 350°F, using a thermometer to monitor the temperature for consistent results.
04 - Working in small batches to avoid overcrowding, carefully lower potato slices into the hot oil. Fry for 3 to 4 minutes per batch, gently stirring occasionally, until each chip is golden brown and crisp. Transfer finished chips to a paper towel-lined plate to drain.
05 - In a small saucepan over low heat, melt the unsalted butter. Pour in the hot sauce and whisk continuously until the mixture is smooth, well blended, and heated through. Remove from heat and set aside.
06 - While the chips are still warm, toss them in a large mixing bowl with garlic powder, smoked paprika, salt, black pepper, and cayenne pepper if using. Ensure each chip is evenly coated with the spice blend.
07 - Drizzle the prepared Buffalo sauce over the seasoned chips and toss gently until every chip has an even, glossy coating of sauce. Work quickly to maintain crispness.
08 - Transfer the chips to a serving platter immediately. Top with blue cheese crumbles or a drizzle of ranch dressing if desired, and finish with a scattering of freshly chopped chives or green onions. Serve at once while hot and crispy.
