Spam (spiced ham), produced by Hormel, is the grand daddy of luncheon meat. Spam was invented and issued as an easy and preserved protein for the American GIs (solders) during the Korean War, hence the popularity of luncheon meat in Korea.
Thx. Mr. HCG for your generous sharing of info. on luncheon meats through which I've learned quite a bit on this subject. Thx. again for your good work/lesson.
