In a saucepan, boil the daikon with 1 1/4 cups of water and a pinch of salt. Cook until soft, about 6 to 8 minutes. Drain well. In a large bowl, mix rice flour, salt, pepper and sugar. Stir in 1 1/4 cup of water until mixture is smooth. Add the drained daikon, lapchong and dried shrimp then transfer mix to a 2 quart saucepan and cook on medium heat, constantly stirring. The mix will come to a boil and start to thicken. Immediately pour mixture into a 10-inch cake pan that has been oiled and lined with oiled parchment. Place pan in steamer for 1 1/2 to 2 hours until set. Remove cake from steamer and allow to cool completely before slicing into 1/2-inch slices. In a non-stick pan add a touch of oil and pan fry both sides of slices golden brown.
OYSTER RAGOUT: In a small saucepan coated with oil, caramelize the shallots. Add the oyster sauce, sugar and chicken stock. Reduce by 50 percent. Check for seasoning. Add butter. Add oysters to just warm them.
PLATING On small plates, cover with oyster ragout and top with hot turnip cake. Garnish with scallions.
