If any large pieces of potato remain after processing, chop them coarsely by hand. To make handling the uncooked tots easier, use a wet knife blade and wet hands. Once the tots are added to the hot oil, they may stick together; resist the temptation to stir and break them apart until after they have browned and set. You will need at least a 6-quart dutch oven for this recipe.

2 1/4 tsp. salt
2 1/2 pounds russet potatoes, peeled and cut into 1 1/2-inch pieces
1 1/2 T. all-purpose flour
1/2 tsp. pepper
1 quart peanut or vegetable oil
Whisk 1 C. water and salt together in bowl until salt dissolves. Pulse potatoes and salt water in food processor until coarsely ground, 10 to 12 pulses, stirring occasionally. Drain mixture in fine-mesh strainer, pressing potatoes with rubber spatula until dry (liquid should measure about 1 1/2 C.); discard liquid. Transfer potatoes to bowl and microwave, uncovered, until dry and sticky, 8 to 10 minutes, stirring halfway through cooking. Stir flour and pepper into potatoes. Spread potato mixture into thin layer over large sheet of aluminum foil and let cool for 10 minutes. Push potatoes to center of foil and place foil and potatoes in 8-inch square baking pan. Push foil into corners and up sides of pan, smoothing it flush to pan. Press potato mixture tightly and evenly into pan. Freeze, uncovered, until firm, about 30 minutes. Meanwhile, adjust oven rack to middle position and heat oven to 200 degrees. Set wire rack in rimmed baking sheet. Add oil to large Dutch oven until it measures about 3/4 inch deep and heat over high heat until 375 degrees. Using foil overhang, lift potatoes from pan and cut into 48 pieces (5 cuts in 1 direction and 7 in other). Fry half of potato tots until golden brown and crisp, 5 to 7 minutes, stirring only after they are browned and set. Transfer to prepared baking sheet and place in oven. Return oil to 375 degrees and repeat with remaining potato tots. Serve.
