Method
Whisk together the ketchup, sweet chili sauce, light soy sauce, rice vinegar, sugar and 50 ml water in a small bowl; set aside.
In a medium bowl whisk the sweet potato starch with 120 ml cold water until smooth; add 1/4 tsp salt and 1/8 tsp white pepper.
Letting the slurry rest 5 minutes helps the starch hydrate and gives a better glossy texture.
Separate scallion whites and greens; lightly beat the eggs in a small bowl.
Heat a 10-inch (25 cm) nonstick or well-seasoned cast-iron skillet over medium-high heat until hot.
Add 2 tablespoons oil to the pan, then add the scallion whites and cook, stirring, about 30 seconds until fragrant.
Add the drained oysters in a single layer and cook undisturbed until their edges just start to firm, about 1 minute.
Oysters cook very quickly; watch for them to plump and the edges to curl slightly.
Pour the starch slurry over the oysters and, using a spatula, gently spread so it covers the pan. Cook until the slurry becomes glossy and just thickens, about 1 minute.
Push the oyster-starch mixture to one side of the pan. Add the remaining 1 tablespoon oil to the empty side and pour in the beaten eggs, tilting the pan to make a thin omelette.
When the eggs are mostly set but still slightly soft on top (about 1 minute), fold the oyster-starch mixture over the eggs. Scatter the lettuce and scallion greens over or under the omelette as you prefer.
If you like a slightly crisper edge, let the omelette sit 20–30 seconds before folding.
Press gently with the spatula and cook until eggs are fully set and the interior is hot, about 1–2 minutes.
While the omelette finishes, transfer the prepared sauce to a small saucepan, bring to a simmer over medium heat, then whisk in the cornstarch slurry and simmer until glossy and thickened, about 1 minute.
Slide the omelette onto a serving plate, spoon the hot sauce over the top, and serve immediately with steamed rice or as-is.
Worth knowing
- Sweet potato starch gives the classic chew and glossy look; if you only have tapioca starch, use it but the texture will be slightly different.
- If fresh oysters are hard to find, shelled small shrimp (about 150 g) work—briefly pat dry before cooking to reduce splatter.
- Don't overcook the oysters — they should be just firm. Overcooked oysters become rubbery.
- Street versions often place the omelette on a lettuce leaf; that lift of freshness is nice and helps cut the richness.
- If you need this gluten-free, use a tamari or gluten-free soy sauce.
