Walk into any dim sum parlor in Hong Kong or Guangzhou on a Sunday morning and you'll hear it before you see it. That rhythmic, searing hiss of chilled radish cakes hitting a flat-top grill. It’s a sound that promises a specific kind of magic: a crispy, golden exterior giving way to a creamy, almost molten center studded with savory bits of cured meat. Honestly, making a lo bak go recipe at home is a rite of passage for any serious home cook, but most people mess it up on their first try. I did. My first batch was a gummy, flavorless brick that stuck to the pan like industrial adhesive.
The problem is usually the radish. Or the flour ratio. Actually, it's usually both.
The Radish Reality Check
Most English-language recipes call it "Turnip Cake." That’s technically a lie. We aren't using those little purple-topped European turnips. We’re using daikon, the long, icy-white radish that's about 90% water. If you get the water content wrong, your cake is doomed.
You need to shred the radish. Don't use a fine zester; you want some texture. Use the large holes on a box grater. When you cook the radish shreds in a wok, they’ll release a staggering amount of liquid. Do not throw this away. This liquid is the "soul" of the cake. It carries that slightly pungent, sweet radish aroma that defines the dish. If you swap it for plain water, you're basically eating steamed flour.

Chinese grandmas will tell you that the radish-to-flour ratio is the difference between a high-end restaurant cake and a cheap, floury supermarket version. A good rule of thumb is roughly 3 parts radish to 1 part flour by weight. If you go higher on the radish, the cake becomes incredibly delicate and delicious, but it’s a nightmare to pan-fry because it won't hold its shape.
The Flour Mystery
Rice flour is the backbone here, but not just any rice flour. You need "long-grain" rice flour (often in the red bag in Asian grocery stores). Some people try to use glutinous rice flour (green bag), but that’s a mistake. Unless you want a sticky, chewy mochi-like texture, stay away from the green bag.
For that "restaurant" bounce, many chefs, like the legendary Yan Can Cook or the creators over at Woks of Life, suggest adding a tablespoon or two of wheat starch or cornstarch. This adds a bit of translucency and a "snap" to the texture. Without it, the cake can feel a bit muddy on the tongue.
The Umami Powerhouse Ingredients
A lo bak go recipe is only as good as its mix-ins. You can't just throw in some ham and call it a day.
- Lap Cheong (Chinese Sausage): These are sweet, fatty, and essential. Dice them small. When they hit the hot pan, the fat renders out and flavors the radish.
- Dried Shrimp: These little guys are flavor bombs. You have to soak them first, then chop them finely. If you leave them whole, someone's going to find a "toenail" in their cake. Not ideal.
- Dried Scallops (Conpoy): This is the "luxury" ingredient. They are expensive. If you’re on a budget, skip them, but if you want that deep, oceanic savoriness found in high-end teahouses, shred some soaked scallops into the batter.
- Shiitake Mushrooms: Use dried, not fresh. Dried mushrooms have a concentrated earthiness that fresh ones can't touch.
Sauté these aromatics first. You want them fragrant and slightly browned before they ever meet the radish water.

The Steaming Struggle
Once you’ve mixed your cooked radish, its juices, the flour, and the sautéed meats into a thick slurry, it’s time to steam. This is where people get impatient. You’re looking at 45 to 60 minutes of steaming.
If you under-steam it, the flour won't fully hydrate, and you'll taste raw starch. If you don't grease your pan properly? Good luck getting it out in one piece. Use a neutral oil—canola or grapeseed. Avoid olive oil; it tastes weird here.
The Secret Cooling Phase
Here is the part everyone ignores: You cannot eat lo bak go straight out of the steamer. Well, you can, but it will be a mushy mess.
The cake needs to set. It needs to spend at least 4 hours, preferably overnight, in the fridge. This allows the starches to retrograde and firm up. Once it’s cold and solid, you can slice it into neat rectangles. This is the only way to get those clean, sharp edges that look so good on a plate.
Pan-Frying for Perfection
This is the final hurdle. You want a non-stick pan or a very well-seasoned cast iron. Use a medium heat. If the heat is too high, the outside burns before the inside gets hot.
You’re looking for a "crust." It should be deep gold. Some people like to dip the slices in a tiny bit of extra rice flour before frying for extra crunch, but honestly, if your batter ratio was right, you won't need it. The natural sugars in the radish will caramelize and create that crust for you.

Why Some Recipes Taste Bitter
Sometimes you follow a lo bak go recipe perfectly and it still tastes... off. Bitter, even. This usually comes down to the radish itself. Old, oversized daikon can develop a bitter, woody core.
To fix this, some old-school chefs blanch the shredded radish in boiling water for a minute and drain it before the main simmer. This removes some of the "sharpness." Also, adding a pinch of white sugar to the batter acts as a bridge between the savory meat and the pungent radish. It balances the whole thing out.
Don't forget the white pepper. Lots of it. It provides a floral heat that black pepper just can't replicate.
Troubleshooting Your Lo Bak Go
If your cake is too soft to slice even after chilling, you didn't cook off enough radish water or your flour measurement was light. Don't throw it out. You can actually scramble it in a pan with some bean sprouts and X.O. sauce—it’s a dish called "Stir-fried Turnip Cake" and it's a common way to rescue "failed" batches.
If it's too hard or rubbery, you used too much starch and not enough radish. Next time, weigh your ingredients instead of using cups. Radish sizes vary wildly, and "one medium radish" is a recipe for disaster.
Actionable Steps for Your Kitchen
- Buy a digital scale. Stop measuring flour by volume. Aim for a ratio of 300g rice flour to every 1kg of raw, untrimmed daikon radish.
- Prep the day before. Steam the cake on Saturday evening. Let it sleep in the fridge. Fry it for Sunday brunch. This is how the pros do it.
- Don't skimp on the soaking liquid. Use the water you used to soak the dried shrimp and mushrooms as part of your liquid base. It's liquid gold.
- The "Knife Test." When steaming, poke the center with a chopstick or knife. It should come out mostly clean, like a cheesecake. If it looks like liquid milk, keep steaming.
- Serve it right. You need two things on the side: a high-quality chili oil (Lao Gan Ma works, but homemade is better) and maybe a little dish of oyster sauce or sweet soy.
Mastering the lo bak go recipe takes a few tries to get the "feel" for the batter consistency. It should be thick enough to hold a spoon upright for a second before it slowly tips over. Once you nail that texture, you'll never buy the frozen, preservative-laden blocks from the store again.
