Salak: Snake-Skin Fruit With Sweet-Tart Cloves

Salak / Snake Fruit — สละ (sala) — Salacca zalacca.

Salak — sah-lah — snake-skin scales peel back to firm, ivory cloves of sweet-tart fruit, and here's how to eat it and what the lab tests measured. In lab and animal tests, concentrated salak extract slowed alpha-glucosidase, a starch-digesting enzyme, and post-meal glucose markers. The edible part is the fruit. Salak also delivers iron, which is part of hemoglobin, the protein red blood cells use to carry oxygen. Thai cooks turn it into desserts: Salak Loy Kaew is peeled, seeded fruit simmered in pandan sugar syrup and served cold over crushed ice, while Salak Song Khruang tosses the fruit in a spicy palm-sugar sauce with chili and shrimp paste, then tops it with dried shrimp and sliced chilies. To eat it fresh, peel the snakeskin to reach the firm cloves; each one holds a large inedible seed. A squeeze of lime adds vitamin C, which helps your body absorb the fruit's plant iron. The palm itself is fiercely spined, so wear thick gloves to handle it.

Narration transcript

Opening

Peel back what looks like snake skin — glossy reddish-brown scales — and salak splits into firm, ivory cloves. Salak — สละ, sa-la. You eat those cloves of flesh; each one hides a single big, inedible seed. Eat it fresh, or simmered in pandan syrup for a cold dessert.

สละลอยแก้ว (Salak Loy Kaew)

For salak loy kaew, peeled, seeded salak is simmered in pandan sugar syrup, then served cold over crushed ice.

สละทรงเครื่อง (Salak Song Khruang)

In salak song khruang, the same fruit is tossed in a spicy palm-sugar sauce with chili and shrimp paste, topped with dried shrimp and sliced chilies.

Nutrition summary

Among those ivory cloves, iron is the standout — salak is a good source of it, with only traces of B vitamins.

Iron

Iron is part of hemoglobin, the protein that carries oxygen in your blood, and it supports normal energy metabolism.

Closing

A squeeze of lime over the peeled cloves adds a bright sourness, and it helps your body take up the fruit's iron. Watch the palm itself, though: it bristles with fierce spines, so handle it with thick gloves. Follow Longevity Biome, and LIKE this video for regular updates.
