Taiwanese Street Snack Deep Fried Oyster Cake 台灣小吃炸蚵嗲 - AFF Taiwan Aug 2014

The Taiwanese Street Snack, Deep Fried Oyster Cake (台灣小吃炸蚵嗲) bears a resemblance to one of our local snack - Fuzhou Hao Bing (福州蚝饼). However, other than the use of oysters as filling and the "UFO" shape, there are some differences between the two.

First, the batter. The Taiwanese version uses all-purpose flour with rice flour or corn starch, whereas the Fuzhou Hao Bing batter uses ground rice with soya bean (couldn't find much info about the exact recipe). And the fillings (besides oysters), the Taiwanese oyster cake uses mainly chinese chives, cabbage and spring onion, whereas the Fuzhou Hao Bing includes minced pork, chinese celery and some peanuts as topping.

I love to eat Fuzhou Hao Bing, there's a stall at Maxwell Market which sells quite decent ones and I would usually grab one piece when I go there. So for Asian Food Fest Taiwan, I thought of attempting the Taiwanese version just to taste the difference.

After searching on the net for recipes, I narrowed to two recipes by Taiwan Duck which has a video demo, and another on Xinshipu. Basic ingredients are pretty much similar except for the proportion. The video demo was really useful because the success of the oyster cake lies in the technique during deep-frying.

It took me eight tries before I could produce a decent oyster cake, almost wanted to give up! The technique seemed easy enough, coat a medium size ladle with some oil, add 2-3 tbsp of batter, add 1 tbsp of vegetables, add 2-3 oysters, cover with 2-3 tbsp of batter, dip the the ladle into very hot oil, once the oyster cake turns slightly brown, dislodge it into the oil and deep fry till golden brown. The thing was, I couldn't manage to dislodge the oyster cake from the ladle. The batter was totally stuck, total mess when I tried to pry the cake open!

Initially I used half recipe from Taiwan Duck, after five tries (used up all the batter), I thought perhaps the batter was too watery/thin. So I switched to the recipe on Xinshipu which has a thicker batter which was easily to manage. After two more tries, I finally managed to dislodge the oyster cake into the oil on the eighth try. Realised that if I coat the ladle with more oil, in fact not just coat but leave about half teaspoon of oil in the ladle before adding the batter and ingredients, the whole oyster cake could be dislodged into the oil much easily. In addition, had to reduce the amount of fillings so that it's much easier to handle.

But the problem with the oyster cake with the thicker batter, the texture was too hard and turned rubbery after a while. Yucks, no good. So I went back to the Taiwan Duck recipe, and with the newly mastered technique, yes, managed to produce six decent pieces of oyster cakes!

The oyster cakes were crispy on the outside and a bit chewy inside, I could taste the ocean with the oysters complemented by the aroma of the chives, cabbage and spring onion. Surprisingly quite bland. Good eaten on its own and equally nice with a sauce concocted of ketchup, oyster sauce, chilli and sugar.

It's really quite different from the Fuzhou Haobing which is much more flavourful, crispy and heavy. I could eat a few pieces of this Taiwanese oyster cake at one go but one piece of the Fuzhou Haobing is already quite overwhelming on the palate.

That said, the deep frying work was tedious, and the aftermath of it all, an oily and smelly kitchen :(
Gah, there were a lot of oil splatters especially when I added too much filling or didn't cover the filling properly with the batter. Perhaps once is enough.

Ingredients are simple - a batter of all purpose/plain flour, rice flour, finely chopped cabbage, chinese chives and spring onion and oysters (I bought frozen ones).

Like I mentioned, the key to successful oyster cake (at least to me), was having sufficient oil on the ladle to begin with. See the picture below, there must be enough oil on the ladle such that the oil surrounded the batter beneath and around. In this way, the whole cake could be dislodged easily into the hot oil after frying till slight brown.

  • 1/2 cup rice flour
  • 1 cup water

  1. Rinse the oysters and thaw them in water added with 1 tsp salt. Set aside.
  2. Finely chop the chives, cabbage and spring onion, toss with 1 tsp salt. Set aside.
  3. Mix plain flour, rice flour, water and oil and stir till well-blended.
  4. Heat up cooking oil (sufficient to cover a ladle full of batter) in a deep pot till very hot (more than 160 degree celsius).
  5. Dip the ladle into the oil and remove, leaving about 1 tsp of oil in the ladle.
  6. Add 2 tbsp of batter into the ladle, spreading a bit, then add 2 tsp of the vegetables, spreading and pressing down. Next add  2-3 oysters. Finally cover the top with 2-3 tbsp of batter, make sure that the batter covers all the ingredients.
  7. Dip the entire ladle into the hot oil, make sure the batter is fully submerged. Swirl the ladle around.
  8. Once the oyster cake turns slightly brown, dislodge the cake into the oil with the help of a thin knife (I use butter knife).

  2. Hi Diana,
    I love oysters too! There's another yummy way of eating - deep fried breaded oysters go well with tonkatsu sauce!

  3. Hi.

    I love this cake. I have the same problem as you did. Finally i got the receipt to make first batter pour bigger than the top, that make more solid underneath when dislodge the cake, if not it will be open and whoaaa disintegrate ...
