Method
1
Rehydrate and rinse the jade wood ear
Pick over and rinse 12 g dried jade wood ear. Cover in a roomy bowl with about 500 ml lukewarm drinking water, approximately 30–40°C. Following the pack, soak for 15–30 minutes until the lobes open and are soft throughout. Check and continue as needed, without leaving it at room temperature for prolonged periods; if preparation must wait, cover and move to a fridge at 5°C or below. Discard soaking water, rinse each lobe and tear into 3–4 cm pieces. This is thick white wood ear, not frilly snow fungus; expansion or colour does not prove it is cooked.

2
Cook the jade wood ear first
Cover the rehydrated pieces with about 1 litre fresh drinking water. Bring to the boil and maintain a steady gentle boil for about 40–60 minutes, following the pack, until thoroughly cooked and even the thickest parts are tender enough to bite. Keep submerged, topping up with boiling water if needed. Drain. Do not let the pan boil dry or replace this step with a quick stir-fry. Do not use soaking water.
3
Prepare the prawns and eggs
Thaw frozen prawns fully in the fridge following their pack, drain, pat dry and weigh 200 g prepared prawns. Beat the eggs with sesame oil and about 0.5 g salt. Mix 3 g cornflour with 15 ml cold water; stir again before adding it to the eggs later. Prepare the ginger and spring onions, keeping raw prawn utensils separate from cooked fungi.
4
Cook the prawns
Heat 5 ml oil in a large frying pan over medium heat. Fry the ginger for about 30 seconds. Spread the prawns out, cook for about 2–4 minutes and turn, until firm and opaque with no raw translucent centre. Size and actual doneness determine the time. Transfer to a clean bowl, never the raw prawn bowl, and have the cooked wood ear ready.
5
Gently fold the eggs and combine
Stir the slurry again and beat it into the eggs. Add the remaining 10 ml oil to the pan. Pour in the eggs over medium heat and gently push from the edges towards the centre to make soft folds, not one flat omelette. When mostly set, fold in the cooked wood ear, cooked prawns and spring onions for about 1–2 minutes, until all egg is set and the dish is hot throughout. Continue gently cooking if any liquid raw egg remains. Finish with the remaining salt to taste and serve immediately.

Cooking tips
- Cook the jade wood ear first; the estimate includes the pack cooking stage, so this is not a five-minute dish.
- Weigh prepared prawns. Set the eggs completely while keeping soft folds; do not rely on heat on the plate to finish raw eggs or prawns.
- Jade wood ear is thick white wood ear, distinct from snow fungus; use the corresponding product rather than applying another fungus cooking time.
Allergens
Contains egg, crustaceans from prawns and sesame from sesame oil. The Xianyitang pack states that it is packed in a facility also handling peanuts, tree nuts, sesame and soya. Check every actual ingredient label.
Storage and reheating
Keep raw prawns and rehydrated fungi refrigerated at 5°C or below; follow prawn pack instructions. Separate raw and cooked utensils and clean hands and tools after handling raw prawns. Divide cooked leftovers into shallow containers, cool promptly and refrigerate within 2 hours of cooking. Eat within 48 hours or freeze. Reheat only once until steaming hot throughout.
