Oil for frying Squeeze potato, by the handful, to eliminate liquid, then place in a bowl. Sprinkle cornstarch over potato and toss to distribute cornstarch evenly and loosen shreds. Arrange a handful of shreds inside one sieve in a latticework over the bottom and at least halfway up the side. Fit second sieve inside first. Heat oil to 350 degrees on a deep-frying thermometer, place sieve in pan, and cook nest until light pumpkin color (about 3 or 4 minutes). Remove from oil and lift of top sieve. Loosen edge of nest with tip of a sharp knife, then gently remove nest and drain on paper towels. Makes 4 to -20ºC our inch nests.
