Happy you found the real thing and glad you liked it. If you want spicier go for chorizos. "Real" Landjaegers are seasoned, but not over spiced. Remember: 1. this was a food of the Tuetonic peoples (German, Swiss) and they were never much for heat and 2. This was intended as a burst of energy while out hunting. Consumers of landjaegers normally did not have the luxury of drinking a bunch to quench their thirst so no local bars nearby to down a pint.

BTW, I see a lot of landjaeger wanna-be's out there. If it is not pressed into a square shape it ain't a real landjaeger
Reason for the square shape is that they can stack neater and take up less room in the hunter's "kit"

Happy hunting!
