Taiwanese Oyster Omelet

Ingredients

• 3 tbsp sweet potato starch – whisked with water for batter
• 6 tbsp water – for batter
• 2 large egg – beaten
• 0.25 tsp salt – for eggs
• 0.25 tsp white pepper – for eggs
• 1 cup napa cabbage – thinly sliced
• 4 ounces shucked oysters – drained and patted dry
• 2 tbsp neutral oil – for frying
• 0.5 cup water – for sauce
• 2 tbsp ketchup – for sauce
• 1 tbsp soy sauce – for sauce
• 1 tbsp sugar – for sauce
• 1 tsp rice vinegar – for sauce
• 0.125 tsp white pepper – for sauce
• 1 tsp sweet potato starch – for sauce slurry
• 1 tbsp water – for sauce slurry

Instructions

1. Make the sauce: In a small saucepan, whisk together the water (for sauce), ketchup, soy sauce, sugar, rice vinegar, and white pepper (for sauce). Bring to a simmer over medium heat and cook 2–3 minutes.
2. In a separate cup, stir the sweet potato starch (for sauce slurry) with the water (for sauce slurry) until smooth. Whisk this slurry into the saucepan and simmer, stirring, until glossy and lightly thickened, 30–60 seconds. Remove from heat and keep warm.
3. In a bowl, beat the eggs with the salt and white pepper (for eggs) until well combined. Thinly slice the napa cabbage and set aside.
4. For the batter, whisk the sweet potato starch (for batter) with the water (for batter) until smooth and pourable.
5. Heat a 10–12 inch nonstick skillet over medium-high heat. Add 1 tbsp neutral oil (reserve the remaining 1 tbsp for Step 6). Pour in the starch batter and quickly swirl to a thin round. Cook until the edges set and the center turns translucent, 1–2 minutes.
6. Pat dry the shucked oysters, then scatter them evenly over the batter along with the napa cabbage. Drizzle the reserved 1 tbsp oil around the edges. Cook until the oysters just start to turn opaque and most of the batter is translucent, 1–2 minutes.
7. Pour the beaten mixture over the pan contents and tilt the skillet to spread it evenly. Cook until the eggs are mostly set with a slight sheen on top, 1–2 minutes.
8. Slide a wide spatula under the omelet and flip in one motion. Cook until the eggs are fully set with light golden spots and the oysters are just cooked through, 1–2 minutes. Transfer to a plate.
9. Spoon the warm sauce generously over the omelet and serve immediately.
