Soak potatoes in a large bowl of water for about 30 minutes. Pat dry thoroughly with paper towels. Heat oil in a deep-fryer or large saucepan to 275 degrees F (135 degrees C). Gently add the potatoes in the hot oil for about 5 minutes, stirring and flipping the potatoes occasionally. Remove potatoes from oil with a slotted spoon to drain on paper towel and to cool completely. Heat oil in a deep-fryer or large saucepan to 350 degrees F (175 degrees C). Fry the potatoes again until golden brown, 5 to 6 minutes. Blot with a paper towel. Sprinkle with salt to serve.
Preheat oven to 400 degrees F (200 degrees C). Cut each pita bread into 8 triangles. Place triangles on lined cookie sheet. In a small bowl, combine the oil, pepper, salt, basil and chervil. Brush each triangle with oil mixture. Bake in the preheated oven for about 7 minutes, or until lightly browned and crispy. Watch carefully, as they tend to burn easily!
