Vietnam has between 20 and 30 native varieties, most of them unnamed. There’s some debate whether durian first arrived from Thailand, Malaysia, or even the Philippines but there seems to be a mix of large-spiked Thai varieties and small-spiked Malaysian. Most varieties are very mild and taste more like vanilla than durian, although I thought the wild highlands durian were some of the best durians I have ever tasted, comparable to those I enjoyed in Penang.
Here are a few of the more popular durian varieties in Vietnam.
