Chef Tips from the Video

Troubleshooting
Dumplings are soggy and the wrapper falls apart.
Microwave for a shorter time (2 min) and let them rest uncovered; avoid covering the plate which traps excess steam.
Onion cup collapses when placing dumplings.
Select a firm onion and cut a slightly thicker petal; gently press the interior to reinforce the walls before adding dumplings.
Sauce pools at the bottom and makes the onion soggy.
Drizzle the sauces lightly and serve immediately; excess sauce can be dabbed with a napkin.
Storage
Refrigerator: Store any leftover dumplings in an airtight container for up to 2 days. Reheat in microwave before serving.
Freezer: Uncooked frozen dumplings can remain in the original package for up to 3 months.
Room temperature: Do not store the assembled onion cup at room temperature for more than 1 hour due to food safety.
Make-Ahead Tips
- Prepare the onion cup ahead of time and keep it in the fridge; bring to room temperature before assembling.
- Measure out mayo, chili oil, and hot sauce in a small ramekin for quick drizzling.
