Met Khanun (เม็ดขนุน)

The Sweet That Outlived Its Own Seed

เม็ดขนุน means "jackfruit seed" — and that is exactly what the sweet looks like: a smooth oval, golden on the outside, the size of the seed it imitates. Wikipedia dates it to the Ayutthaya kingdom and lists it among the nine auspicious sweets (ขนมมงคล 9 อย่าง) served at weddings, ordinations and temple fairs. The name is the blessing: ขนุน sounds like หนุน, to support — met khanun wishes the recipient success with people behind them.

It belongs to the golden family of Thai sweets, and its lineage runs through Portuguese Siam. The same kitchen that gave Thailand thong yip, thong yod and foi thong — the egg-yolk confections attributed to Thao Thong Kip Ma (Marie Guimar) at the court of King Narai — produced met khanun one generation later, when Ayutthaya cooks adapted the technique a step further. Thai Wikipedia adds the later legend: when King Chulalongkorn visited Phrom Buri for kathin, the head-cook troupe from Ban Hua Pa served him met khanun among their sweets; he was so taken with the table that he granted the cooks the name แม่ครัวหัวป่าก์, which became the title of a classic Thai cookbook.

Inside the golden skin is a paste of mung bean stirred with coconut milk and sugar — and here is the quiet irony of the recipe's history: the original filling really was the jackfruit seed itself, boiled, peeled and pounded. TrueID's recipe still makes it that way, sun-drying the seeds, peeling both skins, and stirring the pounded white flesh with coconut milk. Most recipes today, though, keep only the shape and swap in mung beans — easier to find, easier to work, and the paste stays smooth and sweet.

The Recipe (mung bean version, from Aroifin)

The real-seed version (TrueID): 800 g boiled, pounded jackfruit seeds stirred with 700 g coconut cream, 200 g sugar and 3–4 g salt for 40 minutes on low heat; the syrup made with jasmine-scented water (น้ำลอยดอกมะลิ), the coating from 12–13 duck yolks. The two-syrup version (Barn FinFin): 300 g mung beans soaked overnight and steamed, blended with 500 ml coconut milk, 200 g sugar and ¼ tsp salt, stirred 20 minutes, shaped, coated in 15 strained duck yolks — then poached in a thick syrup, off the heat at first, and finished in a separate thin pandan syrup. The taro version (Kapook): 500 g steamed taro stirred with 300 g coconut cream, 200 g sugar and ½ tsp salt, poached in a light 1 kg sugar-to-1 litre syrup.

The Method

1. The beans. Wash the hulled mung beans and soak them — Aroifin says two hours, Barn FinFin prefers overnight. Steam until soft (15–20 minutes). The steaming matters: FinFin's note is that pre-steamed beans stir down quickly and reliably, where raw soaked beans may never fully cook in the paste.
2. The paste. Blend the beans with the sugar and coconut milk, then stir (กวน) in a brass or non-stick pan on genuinely low heat. Twenty to thirty minutes, until the paste thickens and pulls away from the pan. Aroifin's rule: if it still sticks to the pan, it will break apart in the syrup. Do not over-dry it either — FinFin warns a too-dry paste cracks when you shape it.
3. The shape. Cool, knead, and roll into ovals the size and shape of jackfruit seeds. Lovethailand notes the traditional alternative: a round, slightly flattened nutmeg (ลูกจันทน์) shape. Keep the shaped pieces covered with a damp cloth while you work, or they dry and crack.
4. The yolk. Duck yolks only — the colour is the whole point. Strain them through muslin so the coating lies smooth; Aroifin says the difference between a glossy, golden met khanun and a mottled one is a fresh, strained yolk.
5. The syrup bath. Dissolve the sugar and water, simmer to a thread or thick-syrup stage. Here the sources split on heat: FinFin drops each yolk-coated piece into the syrup off the heat, so the egg sets before it can froth, then raises the heat; Kapook poaches in a gently boiling syrup; TrueID lets the pieces sit in the warm syrup a few minutes before heating, then turns them. All agree on the finish — lift each piece and rinse it in a thin syrup, or the thick syrup crystallises on the surface as it cools.

Where Thai Sources Disagree

How Western Versions Get It Wrong

• Raw jackfruit seeds in a candy. English-language recipes sometimes treat met khanun as "jackfruit seed candy" made by boiling fresh seeds in syrup. The Thai sweet is a shaped paste; even the seed version peels, boils and pounds the seeds into a stirred paste first. A whole boiled seed is not the dish.
• Chicken eggs. The golden coat comes from duck yolks — richer, deeper in colour, and the source of the sweet's signature amber skin. Chicken yolks give a pale, thin coating that reads as a pale imitation in any Thai sweet shop.
• Oven-baked or fried coatings. The egg coat is poached in syrup, not baked. It is the syrup bath that sets the yolk, glazes the surface and — in the two-syrup method — prevents the sugar crust that a western candy-maker would fight with corn syrup.
• Skipping the stir. Shortcut versions blend the beans and chill the mixture like a modern fudge. The 20–30 minute stir (กวน) is what cooks out the raw bean taste and builds the glossy, shape-holding texture — every Thai source stirs, on low heat, by hand.
• Missing the meaning. Met khanun is one of the nine auspicious sweets; the name is a pun on support and success. Presenting it as an exotic candy misses the reason it appears at weddings and ordinations — and the reason the shape never changes.

UK Ingredient Notes

• Hulled split mung beans (ถั่วเขียวเลาะเปลือก): the yellow split ones — most big supermarkets carry them in the world-food aisle; every Asian grocer has them. Do not use whole green mung beans, which will not give the smooth golden paste.
• Duck eggs: free-range duck eggs from larger supermarkets or farm shops. The yolk count matters more than size — strain them through muslin for a smooth coat.
• Coconut milk: full-fat canned is fine; the thick top cream (หัวกะทิ) is closest to what Thai cooks use.
• Jackfruit seeds for the TrueID version: sold boiled in brine in tins at Thai grocers (เม็ดขนุนต้ม); alternatively, the seeds inside a fresh jackfruit, boiled, peeled and pounded.
• Pandan and jasmine: pandan leaves frozen at Thai grocers; for jasmine-scented water, float fresh jasmine flowers in cold water overnight — or use plain water, as Aroifin's recipe does.
