Preserved egg

Public reference · Home adaptation “Pine flower” refers to the crystal patterns formed on the egg white surface by chemical change during curing; they are visible when the egg is cut and serve as a direct sign of quality. Duck rather than hen eggs are the usual base, giving a translucent brown or dark green white. At a jiudouwan the preserved egg sits with red-oil rabbit and peppercorn chicken as the three cold dishes, first to the table and the least taxing of the set. As an egg product it counts as lacto-ovo vegetarian under this project's convention. Only the three steps of peeling, slicing and dressing are taken from the sources; no dietary-therapy material is used. **The seat record names the dish but not the method**: the local-history account lists preserved egg inside a “cold dishes such as …” clause, with the name only. This version's method is taken from method two of the public encyclopedia entry for dressed preserved egg (peel, halve, arrange, then pour over a dressing of minced garlic and ginger, soy, vinegar, sugar and chilli oil), and has no exclusive correspondence to jiudouwan. **Food-safety point carried into the allergen note**: the cited preserved-egg entry states explicitly that traditional recipes use lead oxide (yellow lead powder), and that lead-free processes now exist (EDTA or FWD replacing the oxide, at 0.12–0.13 kg per 1000 duck eggs). This version therefore **requires lead-free preserved eggs**, and the requirement is stated in the allergen note. **A disclosed downgrade**: the entry's method one fries ginger, garlic and minced pork in hot oil and pours that over. This version instead mixes a cold dressing, because the first three dishes of the banquet are cold plates and hot oil ruins a cold plate. That is an editorial decision, not the original method. **Quantities are editorial and untested**: six eggs and the seasoning weights are scaled for four servings of a cold dish; adjust the sweet-sour balance to taste. **Technique only, no therapeutic claims**: the two cited entries carry a great deal of material on “clearing heat”, “sobering up”, “lowering blood pressure” and beauty; none of it is adopted. Contains egg (preserved egg), soy (light soy) and sesame (sesame oil). **Important: buy only clearly labelled lead-free preserved eggs** — the cited reference records that traditional formulas used lead oxide (yellow lead powder), that residue was a historical problem, and that lead-free processes (EDTA or FWD substitution) now exist. Check the label, keep refrigerated after opening and eat promptly; particular care is warranted for children. Counted as lacto-ovo vegetarian. 阿坝州地方志办公室：传统川菜“九斗碗”（发布 2013-08-09） — Menu source 1.

It records jiudouwan as a Sichuan feast whose “dou” means a large vessel in Sichuan speech, with nine bowls as a minimum and versions of seven or eleven; its contents as home-style dishes made from whatever chicken, duck, fish, pork, eggs and seasonal vegetables the household has, listing peppercorn chicken and liver fried in lard as representative dishes, served in farmyards on improvised stoves. https://newton.com.tw/wiki/%E4%B9%9D%E6%96%97%E7%A2%97/2750801 中文百科全書：涼拌皮蛋（做法二） — Core method (method two): preserved egg, coriander, garlic, red chilli, tomato and lettuce garnish, soy, vinegar, chilli oil and sugar. Peel the eggs, halve them and arrange in a plate; mince the coriander and garlic, slice the red chilli, combine with soy, vinegar, sugar and chilli oil, whisk, and pour over the eggs, garnished with tomato and lettuce. Method one — six eggs cut into quarters, ginger, garlic, minced pork, soy and chilli sauce fried in hot oil and poured over, finished with sugar and scallion — is not used here. https://newton.com.tw/wiki/%E6%B6%BC%E6%8B%8C%E7%9A%AE%E8%9B%8B 中文百科全書：松花蛋（松花皮蛋）——無鉛皮蛋與食品安全 — Supports this entry's safety requirement: the entry records that traditional preserved-egg formulas all used lead oxide (yellow lead powder), that lead being a toxic heavy metal with import bans in some countries, and that substitutes were therefore developed — EDTA used by omitting the oxide and substituting EDTA, at 0.12–0.13 kg per 1000 duck eggs, or FWD used by dissolving 0.5 kg FWD in 75 kg cold water to soak 1500 duck eggs. It also records that older preserved eggs risked lead poisoning on excessive consumption and that lead-free versions are now produced. This version therefore requires lead-free eggs only. https://newton.com.tw/wiki/%E6%9D%BE%E8%8A%B1%E7%9A%AE%E8%9B%8B FDA: Food Allergies — Basis for declaring egg, soy and sesame allergens. https://www.fda.gov/food/food-labeling-nutrition/food-allergies AI-generated illustration; not kitchen-tested.
