Kumquat cake is a candied kumquat confection pressed into shape, made in Yilan — the region that accounts for the vast majority of Taiwan's kumquat cultivation. Facilities supervised by the Dongshan Township Farmers' Association candy and press local kumquats into jinzao gao, sweet-tart and full of fruit aroma.
According to Taiwan's Agriculture Knowledge Portal, Yilan County accounts for over 90% of Taiwan's kumquat cultivation area, with Yuanshan Township (about 45%) and Jiaoxi Township (about 39%) as the two largest growing areas; Dongshan and Sanxing townships also grow kumquats, with the harvest season running from November through March. The Dongshan Township Farmers' Association operates a well-known kumquat processing facility and brand, though Dongshan itself is not the township with the largest cultivation area.
What is Kumquat Cake?
Kumquat cake is made from fresh kumquats that are sugared, then either sun-dried or low-temperature dried, and pressed into shape. The finished pieces are oval and flat, with a bright golden translucency. The first taste is tart, giving way to sweetness, and the peel carries a naturally slightly bitter, clean fragrance. The Dongshan Township Farmers' Association maintains strict standards for raw material quality, and the processing facilities use locally grown kumquats rather than importing from other counties. Beyond kumquat cake, the same product line includes whole candied kumquats (mì jīnzǎo) and kumquat tea, each with its own following.
Dongshan Township has been growing kumquats for over a century, shaped by the humid climate and volcanic soil of the Lanyang Plain, which yields thin-skinned, thick-pulped fruit with balanced acidity. COA agricultural statistics show that Yilan County has long ranked first in Taiwan for kumquat production, with Dongshan and Jiaoxi as the core growing areas. The county government's tourism brochures have consistently listed kumquat cake as a representative Yilan souvenir, and the Dongshan Township Farmers' Association processing facility offers tours.
