The secret to a perfect, jiggly Chinese steamed egg custard lies in using the correct egg-to-liquid ratio (typically 1:2), ensuring the mixture is smooth and free of bubbles, and steaming it gently at a low temperature.
Achieving that signature jiggly texture in Chinese steamed egg custard requires a delicate balance of technique and ingredients. Here's a breakdown:
Egg-to-Liquid Ratio: The most crucial aspect is the ratio of eggs to liquid (water or broth). A general rule of thumb is 1 part egg to 2 parts liquid. This creates the perfect custard consistency. Too much egg, and it will be firm; too much liquid, and it will be watery.
Smooth Mixture: Whisk the eggs and liquid together gently but thoroughly. Avoid creating excessive bubbles. Bubbles can result in a less smooth and less visually appealing custard. Strain the mixture through a fine-mesh sieve to remove any remaining lumps or bubbles. This step is essential for a silky-smooth texture.
Gentle Steaming: Steaming is the key to a jiggly custard. Use a low heat setting and steam the custard gently. High heat will cause the custard to overcook and become rubbery. Cover the bowl with a lid or plastic wrap (poke a few holes for ventilation) to prevent condensation from dripping onto the surface of the custard.
Steaming Time: The steaming time will vary depending on the size of the bowl and the heat of your steamer. Start checking for doneness after about 10-15 minutes. The custard is done when it is set but still has a slight jiggle in the center. A toothpick inserted into the center should come out mostly clean.
Resting Time: After steaming, let the custard rest for a few minutes before serving. This allows it to set further and develop its flavor.
To prevent condensation from dripping onto the custard during steaming, wrap the lid of your steaming pot with a clean kitchen towel. This will absorb any condensation and ensure a smooth, unblemished surface on your custard.
