Hakka Deep-Fried Stuffed Dried Oyster (Yong Hou Si/ 酿蚝豉) – 5 Ingredients

Hakka Deep-Fried Stuffed Dried Oyster (Yong Hou Si/ 酿蚝豉) – 5 Ingredients

My late grandmother used to always make a huge plate of deep-fried oyster balls during Chinese New Year. I remember she would wrap it in caul fat, something that looked like a see-through net which the kid in me found incredibly fascinating.

I truly enjoy the taste and texture of this dish – it’s out of the world! It’s one up from meat balls; perhaps the it’s the morcel of oyster in each of them which contributes to its umami flavour. The rare ingredient, caul fat, when fried, gives this ball extra flavour and crispy texture. What is caul fat?

Auspicious ingredients: dried oyster & water chestnut

The Chinese always serve auspicious sounding dishes during Chinese New Year. Now I know why my grandmother made this for her favourite festival. Dried oyster in Chinese is called (蠔豉; ho xi), which sounds similar to ‘good things’ or ‘good luck’. While water chestnut (荸薺; bíqí) represents unity. These are the things she wished for her family.

Mix 15 pcs chopped oyster + 12 pcs chopped water chestnut + 500 g fish paste + 700 g minced pork. Season with salt + sugar + white pepper. Wrapped a spoonful of mixed meat in caul fat. Steam & fry.


  1. Buy prepared ingredients. While this dish is not difficult to make, it is time consuming. To save time, you may want to buy ready fish paste and minced meat from the market.
  2. Pre-order caul fat. This is not easily available as it’s not a popular ingredient. Do order it ahead from your butcher.
  3. Freezer-friendly. I like to make this a week ahead Chinese New Year. After steaming them, I’ll freeze them in a container. Come reunion dinner, just thaw it and fry. So convenient!
  4. Bake. Instead of frying, you can bake it in the oven too. I prefer this way to avoid consuming more oil than necessary. It can still turn golden brown if you turn on the broiler function.
