In a colander, place potato. Rinse under cold water until water runs clear. Drain. Place potato in center of a clean kitchen towel. Fold over long sides of towel; twist ends tightly to squeeze out excess moisture. In a large bowl, combine potato, onion, egg, thyme, cornstarch, ½ teaspoon salt, paprika, and pepper, tossing to combine.
Divide potato mixture into 4 portions.
In a large skillet, heat oil over medium heat. Carefully place 4 (2¾-inch) ring molds in pan.
Divide potato mixture evenly between molds. Press to pack potato mixture in place. Cook, turning halfway through, until golden brown and crispy, 6 to 10 minutes. Remove from pan and drain on paper towels. Sprinkle evenly with remaining ¼ teaspoon salt. Garnish with thyme, if desired. Serve immediately.
Notes
KITCHEN TIP: You can make the cakes without a ring mold, but the edges won’t be smooth.
