Place 3 or 4 doughnuts at a time into hot fat and fry for 2 to 3 minutes or until golden brown, turning halfway through cooking. Beware of splattering. Drain on paper towel and let cool for 1 minute. Soak doughnuts, one by one, in maple syrup. Drain on wire rack and let cool. Proceed the same way for doughnut holes (cooking only 1 minute).
