Home adaptation note: The report is one portion (200 g beef, about 400 g finished). Quantities below are that portion. Nanmi sauce (nan bi jiang) is a Dai fermented dipping sauce; if you cannot find it, a mix of fermented chilli bean paste with a little fish sauce is a rough home approximation and is labelled as such — it will not taste identical.
Why this works
This is a thirty-second dish wearing a five-minute preparation. Beef is cut two to three millimetres thick, blanched in boiling water for exactly thirty seconds, then shocked in ice water — any longer and it turns tough, which is the report's own warning. The blanched beef is then fried for only twenty seconds with bird's eye chilli, garlic, mint, lime juice and the diluted dipping sauce, with the pan held above one hundred degrees throughout. That short, hot finish is doing two jobs at once: it wilts the mint just enough to release its cool aroma without turning it black, and it heats every component, including the garlic and sauce, past the point where the report considers them safe. The beef is then served with a separate small dish of the same dipping sauce, heated to at least seventy degrees, so diners can dip as they eat. Speed is not a flourish here; it is the technique.

Equipment
- Wok or large skillet — no wok required (adaptation)
- Bowl of ice water for shocking the beef
- Small pre-warmed dish for the dipping sauce
Steps
- Prepare. Slice the beef 2–3 mm thin. Wash and drain the mint. Squeeze the lime. Slice the chillies into rings, crush the garlic, and mix the nanmi sauce with 20 ml water.
- Blanch. Bring water to a boil, add the beef slices, stir apart quickly, and lift out the moment they change colour, about 30 seconds. Plunge into ice water and drain thoroughly — wet beef will spatter in the hot pan.
- Flash-fry. Heat the oil to 160 °C, bloom the chilli rings and garlic for 10 seconds, then add the blanched beef, mint, lime juice, diluted sauce, salt and sugar. Toss on high heat, keeping the pan above 100 °C, for 20 seconds at most, until the mint just softens.
- Serve. Plate the beef in a shallow dish, garnish with reserved mint, and serve with a separate dish of nanmi sauce heated to at least 70 °C. Serve at 60 °C or hotter and eat within 15 minutes, before the mint wilts and weeps.

Technique: Thirty seconds, then twenty
Two clocks run this dish: thirty seconds in boiling water, twenty seconds in the hot pan. Both are ceilings. Go past either and the beef toughens or the mint collapses, and neither can be recovered.
Variations
- Milder: Halve the bird's eye chilli; the lime and mint still carry the Dai character.
- Lemon version: Use lemon juice if limes are unavailable (adaptation); the flavour is rounder and less sharp.
Frequently asked questions
What is nanmi sauce?
A Dai fermented dipping sauce, typically based on fermented soybean or tomato with chilli. It is sold by Yunnan food shops online; the substitute noted above is only approximate.
Why is my beef tough?
The blanch ran past 30 seconds, or the beef was sliced too thick. Slice 2–3 mm and time the blanch.
Why is the dish watery?
The blanched beef was not drained well, or the mint sat too long. Drain thoroughly and serve within 15 minutes.
Storage
Best eaten within 15 minutes of cooking, per the report. Do not store the finished dish; the mint wilts and the beef toughens on reheating.
