Laiyang Taro

Laiyang Taro

Laiyang taro is a product with geographical indication.

　　    Taro was introduced to Laiyang from the south and has a long history of cultivation there.

　　    Due to Laiyang’s mild climate, abundant sunlight, and soil types predominantly consisting of brown earth and cinnamon soil, it is particularly suitable for taro growth. In addition, the Wulong River basin contains large amounts of humus in the soil, resulting in Laiyang taro with thin skin, high starch content, and rich sweetness. In recent years, Laiyang taro has been exported abroad and has gained attention from foreign buyers.

　　    Laiyang is abundant in taro. In the past, rural families often relied on taro when feeding their children. This is because taro has a special function: preventing diarrhea. Children fed with taro rarely suffered from diarrhea.

　　    There is also a custom where, at midnight on New Year’s Eve during the Laiyang people’s vigil, the whole family eats taro to “invite good fortune.” The homophone of taro is “yu tou” (余头), which sounds like “surplus” or “abundance,” symbolizing that the coming year will be prosperous and bountiful.

　　    How to Eat Laiyang Taro

　　    The simplest way to eat it is to boil it, then peel and eat it directly or with sugar.

　　    Locals like to slice or shred freshly peeled taro around the Mid-Autumn Festival and cook it with noodles. The smooth texture is truly unforgettable.

　　    Classic method: Peel fresh taro and let it air-dry for one or two days until the skin becomes slightly harder. Pan-fry it in oil until the skin turns golden, then add an appropriate amount of water and simmer over low heat until the water evaporates. The result is taro that is crispy on the outside and tender on the inside—truly unique in flavor.

　　    Honey-glazed Taro: Peel the taro and pour honey glaze over it. Each step of the specific preparation has its own secret tips, which won’t be detailed here.
