When Warren and I were in Thailand, we asked about pulasan at every place, nursery, seller, you name it, where we visited. No one knew what the hell a pulasan was. My mother-in-law vaguely knew and said people considered them a weed. These were all wild grown plants and most were quickly removed. Even the lady Warren uses to ship plants from Thailand who works in the JJ MKT where any and all plants are sold, had to look the pulasan up in a book! She said maybe they are grown in the southern most part of Thailand. But I'm not risking my head being removed even for a pulasan!
The pulasan are definitely one of the highlights of our trip to PR. The Seebabat flesh is generous and separates from the seed. When at Ian's, we scamper from tree to tree like ants. Another of our PR hosts has a few seedling pulasan that does cling to the seed but the flavor is good enough to ignore the inconveniance.
But everyone has their own tastes and opinions. I don't think Sheehan will ban you from the forum for not liking pulasan! Or will he?

I also have been asking around for Pulasan but the Thai have never heard of that.
