This is a Bavarian specialty called "Öbergruatznloafdl".
It's made from oats, rye beer, Oabatzder cheese and cow hooves.
Traditionally it is served by a proposing husband to a would-be-bride's family. Large amounts of salt are added to symbolize that the marriage won't spoil, and to demonstrate wealth.
Interesting! There is a similar specialty in Austria called Schmiaschrischnuepflmarfl but the ingredients usually include some chamois liver as well. And it's used for a slightly different purpose since it's normally served at a funeral to remind the attendance about the musculature of the legs of the departed.
