Hallabong: The Jeju Flavor You Didn't Know You Needed

If you have ever walked through a Korean grocery store in February and seen a pile of bright orange fruit with a strange bump near the stem, you have met hallabong. The Jeju Island citrus is one of Korea's most distinctive seasonal fruits, prized for being sweeter than a typical tangerine, more aromatic than an orange, and easy to peel by hand. It is also Jeju Island's representative fruit and the star of a multi billion won export industry. Here is everything worth knowing about hallabong, and why Koreans get genuinely excited about it every winter.

What hallabong actually is

Hallabong (한라봉) is a hybrid citrus, created by cross pollinating a kiyomi orange with a ponkan tangerine. The fruit was first developed in Japan in 1972 under the name dekopon, and Jeju Island farmers brought the cultivar over in the early 1990s. The Korean name comes from Hallasan (한라산), the volcanic peak that dominates Jeju Island. The bumpy stem end on each fruit is said to resemble the silhouette of the mountain. Hallabongs are larger than typical mandarins, easy to peel by hand, and almost completely seedless.

The Jeju connection

Jeju has been Korea's citrus capital since before recorded history. Researchers have identified at least 126 distinct citrus varieties on the island, and Jeju farmers were already sending fruit to the Joseon king as tribute in the early 1400s. The most common variety today is the jeju gamgyul, a small easy peel mandarin grown all over the island. Hallabong sits a tier above gamgyul. It is bigger, sweeter, more expensive, and almost always grown inside greenhouses where farmers can control the water level and force the fruit to concentrate sugars. Yi In-ja, a Jeju farmer profiled in The Korea Herald, told the paper she withholds water from her hallabong trees for two months starting in November to push the sugar content higher. The result is a fruit that genuinely tastes more like candy than citrus.

What hallabong tastes like

Imagine the sweetness of an orange, the floral aroma of a mandarin, and the juicy density of a really good California navel, all in one fruit. The flesh is bright orange, the segments separate cleanly, the skin pulls off in one piece. Most Korean adults eat hallabong straight, peeled and shared at the kitchen table during winter evenings. The fruit is in season from December to early April, with the highest quality batches showing up in late January and February. A box of premium hallabong from Jeju runs about 30,000 to 60,000 won (roughly 22 to 45 USD), which is steep for fruit in Korea but justifies the upgrade for special occasions.

Beyond eating it raw

Most hallabong gets eaten fresh, but Jeju cafes and Korean home cooks have turned the fruit into a small specialty economy. The most popular cooked use is hallabong-cha (한라봉차), a hot tea made by simmering hallabong marmalade with hot water and honey. Hallabong bingsu, shaved ice topped with hallabong puree and sweetened condensed milk, is a Jeju summer specialty. The fruit also shows up in seasonal lattes, citrus chocolates, candied peel, ades, and the small craft cosmetics industry on Jeju (hallabong scented lotions and lip balms are everywhere in island tourist shops). For home cooks, hallabong segments are the upgrade ingredient for fruit salad, panna cotta, and roasted duck.

How to actually find one

Inside Korea, every grocery chain stocks hallabong from December through March. The cheaper end runs 10,000 to 20,000 won for a 3 kilogram box, the premium boxes hit 50,000 plus, and Jeju direct shipped boxes labeled as chunhyehyang or red hyang (related cultivars) are the upgrade. Outside Korea, you can sometimes find hallabong at Whole Foods labeled by its Japanese name dekopon, or at Korean grocery stores during the winter. Online retailers in the US ship Jeju hallabong by air for about 80 to 100 USD per box, which is expensive but worth doing once if you want to taste the real thing. If you visit Jeju between January and March, almost every cafe will offer a fresh hallabong ade. The juice straight from the fruit, with just a dash of soda water, is the simplest and best way to taste why Koreans care so much about this citrus.
