Triangular in shape, with a crunchy outer and gooey inner and rich in the tastes of The sea, O Chien, or Oyster Omelette, as it is also known, is a Taiwanese, Malaysian Oyster omelette, a Singaporean treat that has a huge following in Penang Street food hawker centres.
It is a delicious and savoury dish that consists of a crisper and golden omelette with juicy and fatty oysters and a starch batter that is normally accompanied by sharp chilli garlic sauce. The texture of oysters is added with crispy edges of eggs, light chewiness or starch on potatoes, resulting in a multi-sensory experience.
Both as a street snack and as a midnight snack, O Chien recipe is something one cannot afford to miss in case he/she need some snappy and salty goodies. With its alluring smell of the so-called wok hei (breath of the wok), how to make O Chien becomes a classic of the Southeast Asian sense of balancing texture and flavour, as well as a little crispy on the outside, and a little chewy on the inside, but entirely delicious on every account.
About O Chien
O Chien (or Orh Jian in Hokkien dialect) originated in Fujian in China, and it travelled
with Hokkien people to Southeast Asia and changed through time to different regional forms. The dish is usually rather spicier in Malaysia and Singapore, and a thicker, relatively starchy sauce is poured on in the Taiwanese version
The dish is usually available in night markets, and hawkers are promptly made in large, flat, iron works. It is adored because of its complex textures: The paired firmness of the crunchy fried eggs, the texture of the plump oysters, and the sloppy starch mixture, and the remedy of gauging the fried richness is usually by distributing a side of sour chilli or lime slices. This street food oyster omelette stands out for its irresistible charm
Ingredients and Substitutes
- Fresh Oysters: The star of the cuisine. Small Pacific oysters or shucked oysters are best In case fresh oysters are not to be had, they may be refreshed with frozen or bottled oysters, although the flavour may be less pronounced
- Eggs: The foundation of the omelette. Usually 2-3 eggs each serving To make it a rich flavour, duck eggs may be utilised
- Potato Starch or Tapioca Starch: It is mixed with water to a thin batter, and it gives the batter chewiness In a pinch, you can use cornstarch, but it will not provide the same results
- Garlic (minced): Gives a punchy flavour and depth. It is best with freshly minced garlic
- Spring Onions or Chinese Celery: Finely chopped and sprinkled to add freshness and crunch
- Soy Sauce or Fish Sauce: Umami addition Less is more
- White Pepper Powder: Gives a mellow hotness and brings out seafood flavour
- Oil (Lard or vegetable oil is best): Each sheet of the omelette should be fried in oil Lard gives you old-fashioned richness, and vegetable oil is lighter
- Chilli Sauce (serving): A spicy chilli garlic dip will offset the fattiness of such food. Sauces based on lime or vinegar are also good
How to cook O Chien?
Prepare Batter and Oysters
Dilute 2 tablespoons of potato starch or tapioca starch in 4 tablespoons of water into a thin slurry. Wash and drain 1/2 cup of shucked oysters and reserve.
- 1/2 cup fresh oysters
- 2 tablespoons of potato starch
- 4 tbsp of water
Cook the Starch Base
In a large pan or wok, heat 1 tablespoon of oil over medium-high heat. Put in the starch slurry, and let it diffuse. Cook it for about 30-40 minutes and set it slightly translucent. This is what makes the chewy layer under the omelette.
- 1 tbsp of oil
- Starch slurry
Put in Eggs and Garlic
Break 2-3 eggs into the starch layer that is semi-set. Heavily beat up using a spatula and put it smoothly. Put into that 1 tbsp. Minced garlic and a pinch of white pepper. Allow it to cook on one side without any flips or adjustments for 1-2 minutes when its edges start to become crispy.
- 2–3 eggs
- 1 tbsp minced garlic
- White pepper Pinch
Plunge into the Oysters
Add the oysters to the mixture of eggs and spread them around. Put them on, softly
pressing in until they stick. Season with a few drops of fish /soy sauce. Cook for a
further 12 minutes till the oysters are only cooked – do not overcook them; they will go
rubbery.
