My dad was an electrical engineer, he worked with electrical engineers.  It is my opinion that engineers (in a stereotypical world) all think alike.  Anyway, he and his co-workers began growing their own peppers at the office.  Numbering plants and branches, and then grafting hotter branches to hotter plants… I’m sure it was all very scientific.  But in the end they learned that the hotter the dirt, the hotter the pepper… Give some engineers a little knowledge like that and away they go.  They grew some very Hot Jalapeno’s.  And I think a couple wives are still missing their heating pads…
