Wenxian Iron-Rod Yam Banquet 温县铁棍山药宴
Wenxian Iron-Rod Yam Banquet is featured among the local specialties of Henan.
Wenxian Iron-Rod Yam Banquet (温县铁棍山药宴) is a table built on Wen county’s iron-rod yam: a meal of dishes made from the crop that the county in Jiaozuo, Henan, treats as its signature, rather than a single plate with one name.
How the yam is grown and cooked
The county government describes the yam as a crop of the clay-loam soil and of a season: after 霜降 the iron-rod yam reaches its best digging window, and in October 2025 the county held its third 怀山药 gathering at the 陈家沟 growing base. Staff of the county agricultural science institute demonstrated the digging technique on site, and explained both the growing advantage of the county’s yam and its use as food and medicine. The tasting at the same event was of yams steamed on the spot, which is the simplest preparation and the one the county chose to put in front of visitors: no sauce, nothing hidden, just the tuber.
Flavour & texture
The county government sums up the taste in four characters: 甘、甜、面、香 — sweet, sweet-savoury, mealy and fragrant. Steamed, the yam is described as 软糯香甜, soft and glutinous with a sweet fragrance, rather than crisp. The mealiness is the quality most often mentioned: the flesh is dense and floury like a good potato, which is why it carries sauces well in cooked dishes and also stands on its own plain.
Local roots & traditions
Wen county is the original producing area of the 四大怀药 — Chinese yam, rehmannia, chrysanthemum and achyranthes — a group of crops it has grown for more than three thousand years, which is why it is known as the home of the 怀 medicines. Among them the iron-rod yam is ranked first, and the county lists three parallel geographical indications along with a place in the national directory of famous, special and new agricultural products. Jiaozuo’s culture-and-tourism bureau, listing the foods it considers the city’s most flavourful, records 温县四大怀药宴 as the county’s heritage entry and recommends it beside 口口香焖鸡. The county banquet therefore has two names in official use, one naming the four crops and one naming the yam.
Ingredients & dietary needs
The organising ingredient is fresh Chinese yam, dug from the clay-loam fields of Wen county and used both as a vegetable and as a staple. Because a banquet is by definition a set of dishes, the other ingredients depend on the kitchen: the county’s own account describes a steamed tasting, and the yam is commonly cooked with meat or in soup as well, so a vegetarian should ask what the set menu contains. Chinese yam is treated in the county’s writing as both food and medicine, but that is a traditional framing rather than a dietary guarantee.
How to order it
Ask for 铁棍山药宴 or 温县四大怀药宴, and say whether you want the yam on its own or as part of the full set. The simplest order to start from is steamed 铁棍山药, 清蒸 or 现蒸 — the version the county served to visitors at its own harvest event. If you are buying the yam to cook yourself, the fresh crop comes to market after 霜降 and the county promotes it by the growing base at 陈家沟; if you are eating in a restaurant, ask whether the yam in the dish is from Wen county, since that is the point of the name.
Eating it
Steamed iron-rod yam is eaten hot, peeled at the table if the skin is left on, and needs nothing added — the county’s guests tasted it plain. In a full banquet the yam appears across several courses instead of one, so the meal runs from cold dishes through soup to sweets; pace yourself accordingly. The crop is a starchy one, so the yam courses are filling in the way rice or noodles are, and the sensible approach to a full set menu is to treat the yam dishes as the staple rather than as a side.

Luoyang water banquet 洛阳水席 →
洛阳水席 and 温县铁棍山药宴 are both set menus rather than single dishes, and they show two ways of building one. The Luoyang banquet is defined by its serving style — soup after soup, a long sequence of wet dishes. The Wen county table is defined by its ingredient: the iron-rod yam of the county carried through the courses, with the simplest version simply steamed and eaten plain.
