01 - Using a mandoline slicer or a sharp knife, cut the potatoes into thin, even slices approximately 1/8 inch thick.
02 - Submerge the potato slices in a bowl of cold water for 10 minutes to draw out excess starch. Drain thoroughly and pat each slice completely dry with paper towels to ensure crisp frying.
03 - Pour the vegetable oil into a deep fryer or a large heavy-bottomed pot. Heat the oil to 350°F, using a thermometer to monitor the temperature.
04 - Carefully lower the potato slices into the hot oil in small batches. Fry each batch for 3 to 4 minutes until golden brown and crisp. Remove with a slotted spoon and drain on a layer of paper towels.
05 - In a small saucepan, melt the unsalted butter over low heat. Pour in the hot sauce and whisk continuously until the mixture is smooth and heated through.
06 - While the chips are still warm, toss them with the garlic powder, smoked paprika, kosher salt, black pepper, and cayenne pepper until evenly coated.
07 - Drizzle the prepared Buffalo sauce over the seasoned chips or toss them gently in a large bowl until every chip is evenly coated.
08 - Transfer the chips to a serving platter immediately. Top with blue cheese crumbles or a drizzle of ranch dressing and scatter fresh chives over the top, if desired.
