The ideal way to cook the buns is in a stack of Chinese-style bamboo steamer trays. Failing that, a metal steamer is fine – cook in batches, steaming a second batch while you eat the first.
If you don’t want to use peanuts, fried shallots or onions with plenty of salt make great substitutes.
Freezing and defrosting guidelines
Freeze raw or cooked, unfilled. If cooked, cook as instructed and allow to cool completely. Then transfer to an airtight, freezer-safe container, seal and freeze for up to 1-3 months. To serve, defrost thoroughly in the fridge overnight before reheating. To reheat and serve, place on medium heat, stirring occasionally until the dish is heated through.
