1 In A Large Saucepan Of Boiling Salted Water, Cook The Turnip And Potato Cubes For 15 To 17 Minutes, Until They Are Tender, And Drain Them. In A Bowl, Mash Them With A Fork And Stir In The Scallions, The Egg, Flour, And Salt And Pepper To Taste. 2 Coat The Bottom Of A Large, Heavy Bottomed Skillet With About 1/4-Inch Of The Oil. Heat The Pan On Medium High Heat Until The Surface Of The Oil Begins To Shimmer, But Not Smoke. Spoon 1/4-Cup Mounds Of The Turnip Potato Batter Into The Pan, Flattening Them Into 1/2-Inch Thick Patties With The Back Of A Spatula. Fry The Patties Until They Are Golden, Turning Them Once, About 4 Minutes On Each Side. Transfer The Patties To Paper Towels To Drain Off Excess Oil.
