"Create a villain-themed recipe titled 'Dumplings of Doom' for a household of 4. Make it fun and dramatic in presentation, but still practical and delicious. Use omnivore ingredients, moderate budget, intermediate skill level, and a total cooking time of about 30-60 minutes. Include imperial units only. The recipe should feature dumplings with a savory filling and a flavorful dipping sauce, and should be suitable for stovetop or air fryer preparation if helpful."
