Prepare the ingredients. Divide the turnip by half - thinly slice one half and chop the other half into strips (about double the thickness of thin slices), dice the preserved meat sausage, and soak the dried shrimps and dried scallops in water for about 10 minutes. Shred the dried scallops and set aside.
Prepare the batter by mixing rice flour, cornstarch, wheat starch, and tapioca starch in a mixer bowl. Add in seasonings and give it a mix. Stir in water until no lumps.
Boil a pot of water and blanch the turnips. This helps remove the bitterness of turnips. Drain them over a strainer and rinse. Set aside.
Heat some oil in a frying pan over medium heat. Stir-fry the diced preserved meat sausages until fragrant. Add in half amount of dried shrimps, and stir-fry till fragrant.
Add in the rinsed turnips and half amount of dried scallops, stir-fry till slightly golden.
Pour in water and dried shrimp water, then add in slap sugar. Ensure all ingredients are covered in the water, then cover with a lid, and cook for 8-10 minutes.
When the turnips are cooked, turn off the heat. Give the batter a mix again to ensure everything is well combined, then transfer two ladles of batter into the turnip mixture.
Stir the mixture to combine well. The mixture should have a pasty consistency.
Pour the mixture into the batter. Mix in oil. The consistency should be slightly sticky and glutinous.
Grease the 8.5” x 4.5” loaf pan (960ml volume), then pour in the turnip cake mixture. Spread it out evenly.
Top with the remaining dried shrimps and dried scallops.
Cover the tin with aluminium foil, and steam for 45-50 minutes, or until a toothpick comes out clean with just some moist, transparent crumb.
