What to Buy in Lý Sơn Island: Authentic Local Souvenirs

Lý Sơn produces two distinct garlic types: standard multi-clove garlic and single-clove garlic (*tỏi cô đơn*). Both varieties grow in volcanic basalt soil layered with white coral sand. This specific soil gives the bulbs a mild aroma, delicate crunch, and sweet finish without lingering sulfur heat. Multi-clove garlic is affordable for daily cooking, with prices from $5 (approximate) per kilogram. Single-clove garlic costs significantly more because each stem produces only one small, concentrated bulb. Buy bulbs with dry, tight outer skins directly from local farm houses or cooperatives near Bến Đình port.

Lý Sơn purple shallots (*hành tím Lý Sơn*) are smaller, firmer, and milder than common mainland varieties. Island farmers rotate onion and garlic crops across the volcanic fields throughout the year. The bulbs have thin purple skin, crisp flesh, and low pungency, making them ideal for slicing raw into salads or quick-pickling. Dry bunches tied with straw travel easily without rotting. Prices start from $2 (approximate) per kilogram at local farm stalls across An Vĩnh and An Hải communes.

Dried carragheen seaweed (*rau chân vịt*) is harvested by hand from submerged volcanic reefs around the island shores. Harvesters wash the fresh algae in sea water and sun-dry it on basalt stones. Locals boil the dried weed with water and lime juice to set *xu xoa*, a firm, cooling jelly eaten with ginger syrup. Look for clean, golden-brown dried clusters with minimal sand residue at Lý Sơn Central Market. One 500-gram bag yields several batches of homemade dessert.

Buy directly from farm households around the foot of Thới Lới mountain or inside the Lý Sơn Central Market in An Vĩnh. The central market opens at 06:00 daily, selling freshly dried squid, salted anchovy sauce, and seasonal spices. For packaged agricultural goods with verifiable origin stamps, visit the certified agricultural processing shops along the main road leading away from Bến Đình pier. Avoid street carts near tourist boats that offer unusually cheap single-clove garlic.
