Sounds like they might have been some of the Thai peppers FA. That's exactly what they look like and they are plenty damned hot, with a very different flavor from any other pepper I've come across. My Korean friends grow 2 different varieties of 'em here, one like you described and another that more resembles a typical Mexican Chile pepper that get up to 1- 1 1/2" long, but much hotter than the Mexican peppers. I have both varieties in a gallon zip lock bag in the freezer and both will be gettin planted in my garden next spring along with a good crop of plain ol jalapenos
